Thomas had firsthand experience of the power struggle
between Pope and Emperor in which his kinsfolk were deeply and
sometimes fatally involved.
Self effacing as his writing is, Thomas
SEO Service  occasionally alludes to his
family’s military tradition. In connection with the virtue of
courage, for example, he unexpectedly cites African Mango Vegetius Renatus, the
4th century ad author of the most studied handbook of Roman
military strategy: soldiers may act bravely without the virtue
simply because of plus size wedding dresses their training: ‘No one fears to do what he is sure
he has well learnt’ – ‘as Vegetius says’ (ST 2/2.123.1). Perhaps the
book was in his father’s library at Roccasecca. Elsewhere Thomas
writes as if he had dipped into the trade show booth Strategemata of Sextus Julius
Frontinus (c. ad 40–193, governor of Britain 75–78), an anthology
for the use of military leaders: it would be immoral to deceive the
enemy by lying, but one may  lawfully use subterfuge in just wars
(ST 2/2.40.3).

More broadly, Thomas compares penny stocks to watch ascetical practices by which
novices are inducted into monastic life leather furniture with the training to which
recruits in the military are subjected. Again, noting that we can get
angry irrationally, he remarks that ‘a writer may throw down his
pen and a rider beat his horse’, electric cigarettes spontaneously snoring chin strap comparing his
own studious experience with the outdoor life of his brothers
(ST 1/2.46.7). Again, he recalls that there baby shower cakes is one law for the military
and another for merchants: when a knight  is deprived of his status
he falls under the law relating to peasants or tradesmen – perhaps
a hint there of his family’s position in the feudal hierarchy
(ST 1/2.91.6).
On the whole, however, Thomas ignores the wider turmoil in
which his family was embroiled. He acknowledges the possibility of
establishing a religious order of monks to fight for the Holy Land
(ST 2/2.188.3), for example, but  never considers the morality of the
crusades, as we might have expected. (One of the pleasures of
reading a medieval author is to discover what it never occurred to
him or her to  discuss.) Going on crusade was a fact of life,
presumably, which raised no theological questions. In the early
1240s, in Paris, Thomas must have pokies been aware of the preparations
for the crusade to be led by his pokies austere and pious patron and
admirer King Louis IX. Much later, in a seminar pokies, asked whether
risking one’s wife’s chastity by going on crusade without her was
justified, Thomas replies that pokies, if she has good reason not to come,
and is not willing to be chaste in one’s absence, one should not go –
which sounds dismayingly like celibate male jocularity.
Unsurprisingly, in connection with email lists waging war, Thomas considers
whether soldiering is always a sin (ST 2/2.40.1). Early Christians
regarded military life, with its commitment to sole f80 shedding blood on
occasion, as unacceptable. By his day, however, soldiering was
acceptable. He sets out three conditions for making war lawfully.
First, only a prince may sole f63 initiate military action. Second, there must
be a just cause: the enemy must have violated the rights of one’s
community. Third, the intention of those making war must be
Thomas Aquinas and his total gym xls
6
right: they
leather furniture must intend to promote good or avoid evil. In effect,
going to war to redress an injury must not be likely to do more
harm than leaving the injury unaddressed. Thus Thomas endorses
the just war ethics that had been standard since Augustine of
Hippo (354–430).
Thomas says surprisingly little about the relationship between
Church and state and uggs, despite intense discussion among canon lawyers
at the time. Besides the local conflict in which the family was
involved, he must have been aware of the Investiture Controversy,
the long running dispute quick payday loan between the Holy Roman Emperor and
the Pope, formally settled in 1122, over who should invest bishops
and abbots with their rings and crosiers. In his commentary on the
Sentences of Peter Lombard, early in his career, he states that the
Pope, in virtue of his office, is spiritual head of the Church: every
political addition to this essentially spiritual authority is an
historical accident . Thomas shows little interest in the political role
of the papacy. Again, however, he may have taken it for granted.
Thomas must have been aware of legislation promulgated in 1231
by Frederick II in
diabetic diet which blasphemy, games of chance, adultery,
prostitution, and the dispensing of love potions were made
punishable offences. His brothers must have joked about it. In
1254, more challengingly, he could not have failed to reflect on the
legislation passed by  Louis IX providing for the punishment of
heretics and those sheltering them but also against taking the holy
name in cursing or swearing,  engaging in games of chance,
gambling, and suchlike, in effect seeking to enforce morality by
law. A deeply religious man, Louis IX built the Sainte Chapelle in
Paris (c. 1245–8) to house Christ’s crown of work from home thorns. He was to die at
Tunis, in 1270, on a second crusade to the Holy Land. To back his
decision to repress vice by legislation, he appealed to Christian
principles. Interestingly, however, while Thomas argued weight loss pills that the
purpose of law is to make human beings good (ST 1/2.95), he
denied that legislation was always the right way to control vice
(ST 1/2.96). On the contrary, legislation should concern ‘only the
Life
and
times
7
more grievous vices’ – which these are he leaves to the judgement
of reason.
There is less evidence in his work of Thomas’s early monastic
formation, or rather, it is so pervasive as to be almost invisible.
In 1230/1, Thomas was sent to school at the nearby Benedictine
abbey of Monte Cassino, ten miles east of Roccasecca, at first with
his own servant. Founded about 529 by Benedict of Nursia
(c. 480–c. 550) the monastery was, and remains, the cradle of
Western monasticism. Rebuilt after Allied bombing in 1944, the
abbey that Thomas knew was ruined in 1349 by an earthquake. His
father made a donation to repair two mills on the abbey estate, the
profit from which was to pay for an  annual banquet for the monks.
He may have hoped that his youngest son would eventually become
abbot. For the next seven or eight years, Thomas was immersed
in Latin liturgical and biblical patristic culture, no doubt learning
swathes of the Bible by heart –  the Vulgate, of course; Thomas
never learned Greek, let alone Hebrew. He frequently quotes from
the Apocrypha, particularly the Wisdom of Solomon and
Ecclesiasticus, the writings received from Hellenistic Judaism, and
rejected by the Protestant leadership at the Reformation.
Thomas discusses whether children under the age of puberty
(14 for boys, 12 for girls, he thinks) should be admitted as monks or
nuns: with permission of their parents they may be accepted as
oblates, to be educated (as he himself was); they may not be
professed, however, until they have the full use of wedding rings reason, are able
to exercise free will, and are therefore no longer under their fathers’
dominion (ST 2/2.189.5). If parents are in such need that they
cannot be properly supported without the help of their children,
then, according to Church law, these children may not become
monks or nuns (ST 2/2.189.6). To the argument that one should
not enter monastic life without first discussing it with friends,
Thomas grants, citing Aristotle, that long deliberation and the
advice of others are necessary in such life defining decisions; but
he goes on to cite Scripture seo firms against bowing to the wishes of one’s

family, when one has no doubt about one’s call from God
(ST 2/2.189.10). His hair removal for women family did their best to prevent Thomas from
joining the Order of Preachers: since he was by then at least 18
years of age, he did not need Cosmetic Surgery Thailand his father’s permission. It is a standard
topic in ecclesiastical law: Thomas must have had feelings about
the matter, though he remains characteristically dispassionate.
The next phase in his education was dramatic. In March 1239,
hostilities between the Holy replica bags Roman Emperor and the Pope
intensified. Frederick II’s troops occupied Monte Cassino.
Thomas’s father was one of the officers entrusted with guarding
prisoners captured at the battle of Cortenuova, some 18 months
previously, when, with up to 10,000 Apulian Muslim archers,
Frederick II defeated the city states in Lombardy. In the fall of
1239, Landolfo dispatched his son down the road to Naples, to
study the liberal arts at the new university, the first founded
independently of the Church, by Frederick II, to train officials for
the imperial service. At this point his father obviously had no
qualms about allowing Thomas to study photocopier rental in a well known anti
papal environment. Here Thomas would meet the Dominican
friars, something the family did not anticipate or welcome.
Thomas presumably studied the seven liberal arts: Aristotle’s logic,
grammar in classical Latin texts, rhetoric through Cicero,
arithmetic, music and harmonic theory, Euclid’s geometry, and
Ptolemy’s astronomy. Less conventionally, he was introduced to
Aristotle’s natural philosophy, which was still banned in papally
founded universities, as at Paris, by a certain Peter of Ireland
(c. 1200–60). His commentary on Aristotle’s On Interpretation
seems to have been at hand when Thomas composed his own
commentary, back in Naples, about 30 years later.
The college at Naples was only a satellite of the Latin, Jewish, and
Muslim cultures that interacted in Frederick II’s court in Palermo.
Michael Scot (1175–1232?), who learned Arabic at Toledo,
settled in Palermo, where he translated Aristotle (from Arabic into
Thomas
Aquinas
10
Latin) as well as commentaries on Aristotle by the great Spanish
Muslim scholar Ibn Rushd (1126–98), whom the Latins called
Averroes. Even if Naples was only an outpost, the significant thing
is that, immersed for a decade in traditional monasticism, by the
time he was 20 Thomas had also been exposed to the exotic culture
that was opening up more freely and fully than ever before: the
world of Aristotle, largely unknown in the West, communicated
through translation from Arabic, with Islamic commentaries and
interpretations. He was never to leave this inheritance behind.
In Naples, about 1242/3, Thomas decided to join the treadclimber reviews Dominican
friars. Founded by the Spaniard Dominic (c. 1172–1221) a quarter
of a century earlier, the Order of Preachers originated in the
attempt by the Catholic Church to combat the widespread heresy of
the Albigensians (see Chapter 3). Like the Franciscans, founded
about the same time, Dominican friars – from the Latin fratres,
‘brothers’ – were a novelty, a new kind of monk, living in cities
rather than in remote rural estates; clergy yet not under the
immediate jurisdiction of the local bishop; thus something of a
threat to the ecclesiastical establishment, with a system of
governance based on frequent elections and fixed short terms in
office. Thomas could not have been attracted by Dominican liturgy
and conventual life, however – it did not exist in Naples, as since
1239 Frederick II had allowed only two friars to remain in the city.
Thomas was clothed as a novice, probably in April 1244, by
Tommaso Agni, who was to die in 1277 as Latin patriarch of
Jerusalem – another indication of the spacious world that Thomas
inhabited. The Aquino family were horrified. Seemingly at his
mother’s behest, Thomas was kidnapped by a squad of Frederick II’s
soldiers, including his brother Rinaldo, and kept prisoner for
over a year, probably at Roccasecca, until, seeing his determination
(he resisted the prostitute whom they introduced into his
apartment), he was allowed to return to the Dominicans.
Why was Thomas drawn to join the Dominican friars? Thomas
remained loyal to Monte Cassino in his own way, right to the end:

dictated in mid February 1274 probably in his sister’s home at
Maenza, his last act as a theologian was to reply to a request by the
abbot to explain a passage in Gregory the Great (c. 540–604) about
the relationship between divine and human freedom – yet clearly
he did not want to spend the rest of his life as a monk at Monte
Cassino. The likeliest thing is that he was excited by the whole new
intellectual world opened up to him at Naples. Late in life,
comparing forms of monastic life with one another, he contended
that there is nothing better than an order instituted ‘for
contemplation and communicating the fruits of contemplation to
others by teaching and preaching’ (ST 2/2.188.7). That sounds like
the Dominican Order’s ideal Proactol.
Thomas was dispatched to Paris. The distance from Naples to Paris
is over 1,000 miles. Friars were forbidden from travelling on
horseback, though he may not have walked all the way. On this, as
on later occasions, he perhaps embarked at Civitavecchia, sailing to
Aigues Mortes then up the Rhoˆne by boat.
In Paris, Thomas attended lectures, notably by his older confrere
the Suabian Dominican Albert the Great (d. 1280, over 80 years
old), one of the greatest scholars of the Middle Ages. The transcript
in his own hand that Thomas made of Albert’s lectures on
Dionysius the Areopagite survives. He attended Albert’s course on
Aristotle’s Nicomachean Ethics. In 1248, he accompanied Albert to
Cologne, to set up a new study centre. They arrived in time to
witness the laying of the foundation stone of Cologne cathedral.
During this period, Thomas must have been ordained priest,
though no record survives.
In 1252, Thomas returned to Paris. The theology faculty was riven
with strife. The ‘secular masters’, the diocesan clergy who occupied
the principal chairs in theology and law, detested the friars. Being
mostly from northern France and Belgium, they resented the
advent of these interlopers, parachuted into the faculty for a few
years, with allegiances elsewhere and particularly to the papacy. It
Life

13
did not help that, in 1254, the Sicilian Franciscan Gerard of Borgo
San Donnino (c. 1220–76) published a book proclaiming that the
third age of the world had begun, implying that the friars were the
prophets of this ‘new age’. The work was declared heretical, all
copies to be burnt. Thomas’s allusions are as discreet as usual, but
6. Albert the Great, Thomas’s teacher, 1352, by Tommaso da Modena

Aquinas
14
he cannot have been indifferent to this episode. Writing much
later, he states that the New Law of the Gospel is already nothing
less than replica watches ‘the grace of the Holy Spirit given inwardly to Christ’s
faithful’, thus ruling out the idea of any further ‘dispensation of
the Holy Spirit when spiritual men will reign’. This response to the
apocalypticism of Joachim of Fiore (c. 1135–1202) is probably
aimed at the same ideas as reformulated and exaggerated by
Gerard (cf. ST 1/2.106).
Thomas left Paris for Naples at the end of 1259, not expecting ever
to return. He spent the years from 1261 to 1265 at Orvieto. He was
commissioned by Pope Urban IV to compose the liturgy for the
Feast of Corpus Christi. The papal court was a centre of scholarly
endeavour. Albert the Great was in residence, as well as Giovanni
Campano of Novara (1220–96), the mathematician who brought
out a new version of Euclid’s Elements, at Urban’s request. Thomas
began the Catena aurea – the ‘golden chain’, as it was affectionately
known – by far the most read of Thomas’s works well into the
16th century: ‘Perhaps nearly perfect as a conspectus of Patristic
interpretation’, as John Henry Newman wrote in 1841, introducing
the English translation. ‘Other compilations exhibit research,
industry, learning; but this, though a mere compilation, evinces a
masterly command over the whole subject of Theology.’ It is an
immense anthology of patristic texts, culled no doubt from the
library at Monte Cassino among other places.
In 1265, Thomas was assigned by the Order to t shirt printing establish a study
house at Santa Sabina on the Aventine hill, the splendid
5th century basilica given to Saint Dominic in 1221 and still the
headquarters of the Dominican Order. Thomas began to write his
greatest work, the Summa Theologiae. In July 1268, however,
Conradin, Frederick II’s grandson, invaded Rome: Santa Sabina
was sacked by his troops.
Returning to Paris for a second stint as professor, Thomas found
himself in the midst of a crisis provoked by the impact of Aristotle’s
Life
and
times
15
works. For the rest of Thomas’s life there would be hostility
between members of the arts faculty (clergy, of course) and many,
perhaps the majority, in the theology faculty, over how to deal with
the new ideas. At some point he decided to integrate Aristotle with
Christian doctrine. In June 1272, his term over, Thomas returned
to Naples, to continue his commentaries on Aristotle, to write up
his lectures on the Epistles of St Paul, and to complete the Summa
Theologiae.

The best clue to what he was thinking, when he returned from
Paris to Naples in 1272, lies in the letter of condolence that the
professors in the arts faculty at Paris sent to the Dominican Order
in May 1274: ‘For news has come to us which floods us with grief
and amazement, bewilders our understanding, transfixes our very
vitals, and well nigh breaks our hearts’ – there was no such letter
from the theology faculty! They piously asked for Thomas’s bones
for interment in Paris but also, with more chance of success, for
‘some writings of a philosophical nature, begun by him at Paris, left
unfinished at his departure, but completed, we have reason to
believe, in the place to which he was transferred’. Thomas had
promised them translations of the following three works:
Simplicius on Aristotle’s De anima, Proclus on Plato’s Timaeus,
and De aquarum conductibus et ingeniis erigendis. This last seems
to have been the Pneumatics, composed by Hero (or Heron) of
Alexandria (fl. ad c. 10–70), a fascinating catalogue of mechanical
devices working by air, steam, or water pressure. Simplicius of
Cilicia (ad c. 490–c. 560), one of the last pagan Neoplatonists,
wrote a good deal on Aristotle. Proclus belonged to the last
generation of pagan Neoplatonists: his commentary on the
Timaeus, one of the few dialogues of Plato available in Thomas’s
day, was regarded as uniquely valuable. It is striking that the
philosophers at Paris expected Thomas to be in a position to
procure these works for them; we have no idea what he made of
them himself, fascinating as it is to see that he was at least regarded
as at home in this intellectual milieu.
Thomas had also promised them ‘new writings of his own on logic,
such as, when he was about to leave us, we took the liberty of asking
him to write’. Thomas’s commentary on Aristotle’s Posterior
Analytics, begun in Paris and completed in Naples, was sent to
Paris, together with his commentary on the Peri hermenias, started
in Paris but never finished. There is no evidence that members of
the Paris theology faculty ever asked Thomas to write anything
for them.

On 6 December 1273, however, the Feast of Saint Nicholas,
something happened during the celebration of Mass. The result
was that he decided to write no more: ‘Everything I have written
seems to me as straw in comparison with what I have seen.’
Presumably he had some kind of mystical experience. According to
recent commentators, he perhaps suffered a stroke, likely enough
after years of overwork. On the other hand, he was summoned
to take part in the forthcoming Council of the Church due to open
at Lyons. He started out, fell ill on the way, and stopped off with
his kinsfolk. He moved to Fossanova so that he might die in a
monastery. He was nevertheless still clear headed enough, as we
have noted, to dictate a letter to the abbot of Monte Cassino.
Leaving the Summa Theologiae unfinished should be regarded as a
decision by a theologian who knew all along that what could be
said about God could never be finished, or even stated adequately.
Thomas decided to write no more, he was not forced to stop by
physical or mental breakdown or by death.
Interred at Fossanova, Thomas’s remains were moved in 1369, at
Pope Urban V’s behest, to Toulouse (not that Thomas was ever
there). Since 1974 his bones have been housed in the fine
13th century Church of the Jacobins, splendidly restored, and now
a state run museum.

Works
In 25 years of working life, Thomas Aquinas wrote or dictated over
eight million words: two million of commentary on the Bible; a
million on Aristotle; with the rest divided between records of the
disputations at which he presided, many short works, and three
large compendia of Christian doctrine.
Biblical commentaries
Taking students through the Bible was Thomas’s principal duty.
An assistant read out the text and the professor commented,
paraphrasing, citing parallels, and so on. Two important
commentaries have recently been translated into English. The
commentary on the Book of Job (1261–5) focuses on the theology
of providence, the suffering of the innocent, the human condition,
and divine governance. The commentary on the Gospel of John
(1270–2) is increasingly recognized as one of Thomas’s greatest
works. It is, as yet, only among specialists that these works are
much studied: their cut and dried analytical style is so different
from the richly imaginative approach of earlier patristic
commentary (such as Augustine’s), and so different again from the
historical reconstructions of modern biblical exegesis, that the
general reader is unlikely to make headway.
20
Disputed questions

Much of the interest in reading texts from an earlier age lies in
working out how familiar and yet how foreign their preoccupations
and ways of thinking Hiustenpidennykset are. A Christian thinker who died in 1274,
and whose works were entirely composed in Latin, is at several
removes from most of us these days. Good translations and
secondary literature help to make Thomas Aquinas accessible.
Recently scholars have begun to insist on the importance of
studying his biblical Essay writing commentaries. He held a post, after all, as
magister in sacra pagina: professor of sacred Scripture as we
might say. The fact of the matter remains, however, even in
scholarly circles, that the Summa Theologiae is company incorporation cyprus by far the most
discussed of his works. Without much compunction, then, I have
centred this introduction on the Summa, in a necessarily highly
selective reading (it runs to over 1,500,000 words); yet
highlighting issues and insights that are distinctive of Thomas’s
approach, if often provocative and sometimes unacceptable to a
modern reader. Since he divided the Summa in three, I have
devoted a spa cover chapter to each of these parts: much is left aside, of
course, but most of the salient matters are touched on, enough
(I hope) to enable the reader to scale an admittedly pretty
formidable work.
Thomas belonged to a very different

stationary bike stand culture and society from ours.
His writings are far more deeply embedded in his life, upbringing,
and career than a first glance might suggest. I have tried to bring
this out in the first two chapters. Then, in the 750 years since his
heyday, his thought
scabies treatment has
given rise to much controversy, beginning
even before his death. In the last chapter I offer summary accounts
of a handful of these debates – which are by no means all safely
concluded.
Footnoting references, signalling replica watches quotations, and so on were no
part of a 13th century scholar’s duty. He could recycle his own and
his predecessors’ work without a qualm. He knew nothing of
copyright and plagiarism, which are 17th century inventions. That
cannot be my excuse. The free movies online authors whom I list in the further
reading section will, I
hope, forgive my plundering their work in
what is, I am sure they will agree, a good cause. Nobody has ever
written about Thomas Aquinas who did not want his or her

Life and times
The 13th century, sometimes regarded as the great age of
Christendom, with everything in Western Europe controlled by
the Roman Catholic Church, was, on the contrary, an age of
intellectual crisis with much internal dissent. Western Europe was
threatened in the east by a totally alien culture and religion. In
1241, at the battle of Liegnitz, in Silesia, the Mongols, who,
unexpectedly, advanced no further west, defeated a combined force
of Polish conscripts and Bavarian miners. In 1254, Willem van
Ruysbroeck, a Flemish Franciscan missionary sent by King Louis IX
of France, reached the court of the Great Khan in Karakorum, the
Mongol capital, where he debated with Muslim and Buddhist
scholars. Giovanni of Monte
digital signage Corvino (1247–1328), a Franciscan
friar from Naples, translated the Psalms and New Testament into
Mongolian and presented the result to Kublai Khan. Twenty years
younger, if Giovanni had never met Data Mining Software

Thomas Aquinas in Naples,
then he must have known of him.
Tommaso d’Aquino, as he was known to family and neighbours in
the native language of the Roman Campagna, became Thomas
Aquinas when he entered the Latin speaking world of the Catholic
Church – as he remains in English usage. According to his first
biographer, who was present, Thomas died at the then Cistercian
monastery of Fossanova on 7 March 1274, in his 49th year. This
puts his date of birth to 1224/5. He was born a few miles further

south, nearer Naples, in the family castle at Roccasecca, now a
ruin, in what was the county of Aquino, on the border between the
Papal States and the territories ruled by the Holy Roman Emperor
Frederick II of the Hohenstaufen dynasty.
Originally from Lombardy, and ultimately of Norman ancestry,
which no doubt explains why Thomas was relatively tall and fair,
the family had owned Roccasecca since the late 10th century.
Thomas’s mother Theodora no no hair removal belonged to a Neapolitan family. His
father Landolfo was a loyal vassal of Frederick II.
There were at least nine children. Aimo, the eldest son, took part in
the expedition to the Holy Land in 1228/9 when Frederick II
regained Jerusalem and proclaimed himself King in the Holy
Sepulchre Church. On the way home, Aimo was kidnapped by a
Christian warlord in Cyprus. Ransomed in 1233 by Pope Gregory IX,
he transferred allegiance to the papacy. Rinaldo, nearer
Thomas’s age, also served on the Emperor’s side. He deserted in

1245 when Frederick II was deposed by Pope Innocent IV but was
captured and executed for treason. The family regarded Rinaldo as
a martyr for the cause of the Church. Marotta, the eldest sister,
became a Benedictine nun. One sister died in infancy, struck by
lightning steriods, while young Thomas was asleep nearby. Thomas
remained close to his sister Theodora. Her husband and father in
law were implicated in an insurrection against Frederick II. Her
father in law was caught and executed. Her husband fled to the
Papal States but was able to return home after 1268, when Pope
Clement IV finally defeated the Hohenstaufen dynasty. In 1272,
Thomas was executor of his sister Adelasia’s husband’s will.
For all his impact on Aquino family life, we have no idea what
Thomas thought of Frederick II. His contemporaries knew him as
Stupor mundi, the ‘wonder of the world’. His rule stretched from
Sicily to northern Germany. From 1237 until his death in 1250, he
was at war with the Popes, first Gregory IX and then Innocent IV, a
conflict that grew increasingly bitter, cruel, and treacherous on

Much of Thomas’s literary production takes the form of transcripts
of disputations in which he participated. Face to face argument
was an essential part of medieval pedagogy. Disputation as a
method assumes there will be conflicting interpretations of biblical
and other texts that need to be exposed, considered, and resolved.
Thomas proceeds by reformulating a thesis as a question; setting
out arguments that run against the thesis, citing authoritative texts
(Scripture, Augustine, Dionysius the Areopagite, and suchlike);
expounding his preferred answer to the question; and finally
returning to the initial objections, admitting them, suitably
qualified, or rejecting them, one by one. In ST alone, Thomas
sets out about 10,000 arguments against the positions that he
defends – doing so for the most part dispassionately, making the
claims that he will reject as plausible as possible. Of course the
method was not intended to reach compromise or supposed
consensus. It allowed the disputants to discover the strengths as
well as the weaknesses of opposing views; but the aim was to work
out the truth by considering and eliminating error, however
common or plausible or seemingly supported by authority.
We have three substantial collections of edited disputations. From
his first three years of teaching at Paris we have 29 disputed
questions, the first of which gives its name to the collection: De
Veritate – ‘on truth’. These are, in effect, the working papers of the
young theologian. There are two later collections. De Potentia, ‘on
[divine] power’, comprises 10 disputations, all related to questions
considered in the first part of ST (see Chapter 3), dealing then with
the divine nature, the doctrine of creation, and the doctrine of
God as Trinity. The collection De Malo – ‘on evil’ – contains 16
questions on sin, the causes of sin, and so on, Thomas’s best
developed account of these matters.

While good English translations exist, these collections are not the
easiest point of entry even for an advanced student.
Philosophical treatises
Thomas produced several important works of pure philosophy.
In 1270, back in Paris, in the midst of the crisis over the
interpretation of Aristotle, he wrote On the uniqueness of the
intellect against the Averroists. This highly polemical work
concludes as follows:
If anyone, puffing himself up with bogus knowledge, dares to argue
against what I have written, let him not hold forth in corners or in
the presence of the lads, who are incapable of judging such a difficult
subject, but let him write against this book if he dares. You will
then have to deal not just with me, who am the least in this affair, but
also with a crowd of other lovers of truth who know how to resist
your errors and remedy your ignorance.
Naming no names, though everyone must have known who they
were, Thomas inveighs against professors in the arts faculty who
apparently accepted the interpretation of Aristotle’s philosophy of
the mind that was proposed by the Muslim philosopher Ibn Rushd,
whom Thomas denounces as depravator and perversor of
Aristotle’s thought. He denounces these colleagues (clergy of
course) as ‘Averroistas’ but does not let his scorn disrupt the rigour
of the argument. He takes seriously the idea that, instead of each
human being’s having a mind, there is some kind of super mind of
which our individual minds should be regarded as mere
participations. Essentially, his argument is that the Averroist
position cannot explain what it means to say ‘This man thinks’.
Bizarre as it sounds, this resembles 19th century absolute idealism
in the wake of Hegel, according to which the process of history
consists of a single mind that, so to speak, experiences itself. For
Thomas, anyway, this ‘monopsychism’, as we might call it, is
Thomas
Aquinas
22
incompatible with Christian beliefs about the individual soul’s
accountability under divine judgement, though his principal
concern is to clear Aristotle of misinterpretation.
In the same year, Thomas issued On the eternity of the world,
against murmurers, directed against colleagues in the theology
faculty. One of Aristotle’s ‘errors’ was that he believed that the
9. Ibn Rushd (1126 98), the Muslim philosopher
Works
23
world has always existed. Thomas’s eminent Franciscan colleague
Bonaventure argued that it makes no sense to say that a world that
has been created existed from all eternity. Thomas of course
believed that the claim that the world had always existed is false:
the Bible tells us so. However, contrary to what most theologians of
the day believed, he contends that it cannot be proved by reasoning
alone that the world did not exist from eternity. For Thomas, the
concept of createdness has to do with total and radical dependence
on God as first cause of all things – which is a separate issue from
the world’s having a beginning. He saw nothing incoherent in the
idea of a created eternal world. Somewhat provocatively, he claims
that Augustine and Anselm, the greatest authorities in the eyes
of his colleagues, agreed with him. For that matter, his view of
createdness as dependence for existence is not what is commonly
understood by creation today, let alone in his day.
Thomas greatly admired the work of the Persian Muslim thinker
Ibn Sina (980–1037), Avicenna as he was known in Latin, whose
work he had no doubt met at university in Naples. Ibn Sina’s
learning was legendary. (The most influential of his writings was
probably his Canon of Medicine, translated from Arabic into Latin
in the 12th century and reprinted as late as the 17th.) The short
treatise On Being and Essence, composed ‘for his brothers and
companions while he was not yet a master’ – before 1256, then, in
what was to be a widely read treatise – expounds the metaphysical
doctrines held in common by Christians, Jews, and Muslims at the
time. Thomas introduces his most characteristic thesis: in
creatures there is a real distinction between their being (existence)
and essence (nature), whereas in God there can be no such
distinction.
Neoplatonic studies
Thomas owed a great deal to the Corpus Areopagiticum, writings
in Greek by an unknown author who presented himself as
Dionysius the Areopagite, converted by Saint Paul (Acts 17:34).
Thomas
Aquinas
24
Scholars now identify him as an early 6th century monk, probably
based in Syria. To add to his near apostolic authority as Paul’s
supposed disciple, he was identified with the first bishop of Paris,
martyred in the mid 3rd century (on Montmartre), whose remains
were housed in the monastery of St Denis, to the north of Paris,
where the master copy of the Corpus was kept, from which the
translations into Latin were made. Peter Abelard (1079–1142/3)
10. Ibn Sina (980 1037), the Muslim philosopher
Works
25
had to leave the monastery for expressing scepticism about the
latter identification.
In his inaugural lecture as professor (1256), Thomas shows his
debt to Dionysius. The role of theologians, while minor, is
nevertheless honourable, in the cascading descent of divine
wisdom. Things are disposed by divine providence in such a way
that creatures have real effect on one another. To suppose
otherwise diminishes God by denying the power to cause things to
happen with which rational creatures are endowed. Teachers play
a real part in the transmission of knowledge. This is the earliest
instance of the general principle according to which creatures are
genuinely free to play a real part in running the world and working
out their destiny: a principle frequently affirmed by Thomas.
Pseudo Dionysius, as he has been called since his unmasking by
scholars in the 16th century, was indebted to, perhaps taught by,
Neoplatonist thinkers, especially Plotinus (c. 205–70) and Proclus
(c. 410–65), as well as thoroughly immersed in patristic writers up
to Cyril of Alexandria (d. 444). For centuries, in the Greek
Orthodox Church even more than in the Latin West, these writings
had an authority that was only exceeded by the authority of the
Bible itself. Thomas was familiar with all four of the Areopagite’s
works: The Divine Names (the names applying to the divine unity),
The Celestial Hierarchy (on the angels), The Ecclesiastical
Hierarchy (on the mediation between the human and the divine
realms by the hierarchs of the church and the sacraments), and The
Mystical Theology (on the union with the One beyond speech and
knowledge which this mediation secures).
Dating from before 1250, a copy in Thomas’s own hand of Albert
the Great’s commentary on Dionysius’s treatise On the Divine
Names survives in the Biblioteca Nazionale in Naples. His own
commentary, of which there is no English translation, is dated to
the years back in Italy (1261–8). Through his study of Dionysius, he
was well aware of the Christian Platonism that characterizes the
Thomas
Aquinas
26
mystical theology of the Eastern Church. Moreover, several of
Thomas’s key maxims come from Dionysius. For example:
‘we cannot know what [God] is but rather what he is not’
(ST 1.3. Prologue). His account of the angels is permeated with
allusions to Dionysius. He is familiar with Dionysius’s liturgical
vision of the world, which brings the believer into union with the
unknown God – even if he is not really enthusiastic about it.
The other Neoplatonic work on which Thomas wrote a
commentary was the Book of Causes: ascribed to Aristotle (as his
‘theology’) but identified by Thomas as the work of an Arab
philosopher who had borrowed a good deal from Proclus and from
Dionysius. An important thesis, which Thomas appeals to in his
exposition of the eucharist, and which he knows comes from
Proclus, goes as follows: ‘Whatever is produced by secondary
causes is also and more eminently produced by prior causes, since
these are the causes of the secondary causes.’ Of this book there is
an excellently edited English translation. Though the commentary
on the Book of Causes comes late in his career, Thomas cites it
already in his earliest treatise, On Being and Essence.
Commentaries on Aristotle
Much of Thomas’s personal study went into ‘exposition’, as he
usually called it, of works by Aristotle. Having embarked on what
would become the Summa Theologiae, he clearly found Aristotle’s
De Anima very helpful in his own theological account of the soul.
Then, if he did not already know from reports, he soon found on
his return to Paris in 1268 that influential professors in the arts
faculty (clergy, of course), much indebted to the standard Muslim
interpretations, particularly those of Ibn Rushd, were teaching
Aristotle in ways that threatened Catholic orthodoxy.
Thomas’s commentary on Aristotle’s Nicomachean Ethics was
composed in tandem with the analysis of action, virtue, and so on
in the Summa Theologiae.He was obviously delighted to find that a
Works
27
coherent ethics could be developed independently of Christian
beliefs, albeit one that found its fulfilment only in the light of
Christian revelation.
Thomas is palpably at home in Aristotle’s world: a world that is
saturated with purposefulness, a world that is meant to be
understood in the sense that it is our nature as rational beings to
inquire into the world’s order and to come to understand it. Our
sense of the intelligibility of the world is not, for Aristotle or for
Thomas, a projection of mind onto nature, as it seems to many
philosophers and others nowadays. To the contrary, Aristotle’s
world is a projection of intelligible, teleologically ordered nature
onto the human mind.
Good translations exist of the commentaries on Aristotle; it cannot
be said that much interesting study of them is available, and in any
case there is no scholarly consensus as to whether they are creative
or merely pedestrian expositions. Of the 12 studies of Aristotle’s
works that Thomas undertook, 6 were left unfinished. It is striking
that, in what turned out to be his last year, Thomas put so much
effort into these commentaries.
Commentary on Lombard’s Sentences
Of the three major works that Thomas composed, the first was the
massive commentary on the Sentences of Peter Lombard. Peter
Lombard (c. 1095/1100–1161) played a decisive role in the
development of theology as a systematic discipline. The sententiae
are ‘opinions’ culled from vast reading, organized in four books –
God, creation, Christ, the sacraments – and forming the staple of
doctrine teaching at Paris and elsewhere right into the 16th
century. In Thomas’s day and for long afterwards, it was customary
for every would be professor of theology to compose and publish
an exposition of Lombard’s Sentences. More than mere
commentary, this should be seen as an original theological work in
Thomas
Aquinas
28
its own right. Since there is no English translation, and as yet no
critical edition of the original Latin, and relatively little discussion
in the secondary literature, we shall say no more.
Summa Contra Gentiles
The second major work, entitled (not by him) the Summa Contra
Gentiles, he seems to have started in Paris in early 1259. A good
part of the text survives in autograph manuscript. Much revised,
this book reads like an experiment to see how near the ancient
Mediterranean world’s search for wisdom might come to biblical
revelation. The first three of the four books investigate how far the
truths of the Christian faith can be expounded on the basis of
principles available to non believers; only in the fourth do the
arguments depend on specifically Christian revelation. ‘Although
the truth of the Christian faith surpasses the capacity of reason’,
Thomas says at the beginning, ‘nevertheless the truth that human
reason is naturally endowed to know cannot be opposed to the
truth of the Christian faith’ – the implication of which is that for us
‘to be able to see something of the loftiest realities, however thin
and weak the sight may be, is a cause of the greatest joy’.
Summa Theologiae
The third and by far the most famous and most studied work is the
Summa Theologiae, divided into three parts – on (1) God, one and
three, and creator; (2) the journey of the image of God to final
union with God; and (3) Christ as the way – to which our next three
chapters are devoted. Conventionally they are known as prima
pars (the First Part), secunda pars (Second Part), itself divided in
two, and tertia pars (Third Part).
The purpose of the Summa Theologiae, was, as Thomas says, to set
out Christian doctrine in an orderly way, considering how
Works
29
newcomers to this teaching are greatly hindered by various writings
on the subject, partly because of the swarm of pointless questions,
articles, and arguments, partly because essential information is
given according to the requirements of textual commentary or the
occasions of academic debate, partly because repetition has bred
boredom and muddle in their thinking.
(ST 1. Foreword)
While he continued to expound Scripture, and to participate in
disputations, he saw the limitations of these methods of teaching:
line by line exposition made grasp of the whole picture difficult,
while energetic debate favoured increasingly subtle refinements,
not always with the focus on central doctrines of the faith. He
sought, not to replace expounding Scripture in class and debating
issues in formal disputations – indeed he carried on doing both,
and he surely expected his students to participate in both – but to
provide a synoptic guide, a bird’s eye view of Christian doctrine,
laid out systematically.

Chapter 3
Summa Theologiae:
First Part
By any reckoning, the Summa Theologiae counts among the half
dozen great works of Catholic Christian theology. We might as well
stick to the Latin title, since there is no satisfactory translation. It is
neither a summing up nor a re´sume´. In the early 12th century it
meant handy summaries of doctrine. By the mid 13th century,
however, a summa, in other disciplines besides theology, had
become comprehensive, encyclopaedic, organized – not
alphabetically, but according to the author’s viewpoint. ‘Since the
teacher of Catholic truth must teach not only advanced students
but also instruct beginners’, as Thomas says in the Prologue (ST 1),
‘we propose in this work to treat of whatever belongs to the
Christian religion in such a way as may be consistent with the
instruction of beginners.’
How Thomas intended this massive work to be used, or by whom
exactly, we don’t know. It is sometimes such hard going that his
claim to write for ‘beginners’ has been taken as evidence of his
being one more professor with unrealistic expectations. More
charitably, he may have been designing a guide for future
professors, rather than directly for students. He obviously takes it
for granted that his readers have not only completed the standard
liberal arts course but are also proficient in biblical studies. Forty
years later, in 1308 to be precise, the friars engaged in teaching in
31
his home province were ordered not to use the Summa but to stick
to expounding the Sentences of Peter Lombard.
The origins of the Summa are as follows. In 1265, Thomas was
commissioned to teach young friars at Santa Sabina in Rome.
Perhaps they were an elite. He was authorized to return them to
their home priories if they did not perform well. He seems to have
begun by expounding Peter Lombard’s Sentences. A record of the
course, identified some years ago in a 13th century manuscript in
Lincoln College, Oxford, and now entitled the Lectura romana,
covers the nature of holy teaching, the names and attributes of
God, the Trinity, and charity. Thomas was evidently dissatisfied.
Perhaps, as he reflected on the concept of charity, he suddenly
11. Santa Sabina, the Dominican house in Rome
Thomas
Aquinas
32
conceived the plan to rethink the Christian life as a whole in the
light of the four cardinal virtues of prudence, temperance,
fortitude, and justice, as in Aristotle’s Nicomachean Ethics, as well
as the three divinely given virtues of faith, hope, and charity.
Perhaps he saw that much more needed to be said about the moral
life, in a way that would lead his students more effectively into the
practice of the Christian religion.
He hit on an entirely different scheme, which would result in the
Summa as we have it. First he would consider God (to which this
chapter is devoted); then the movement of the rational creature
towards God (Chapter 4); and thirdly (see Chapter 5) he would
consider Christ, who ‘as man is the way for us to tend towards God’
(ST 1.2).
The Thomist axiom
‘Grace does not destroy nature’, as Thomas says (ST 1.1.8 ad 2), ‘but
perfects it, which is why natural reason ministers to faith and the
natural inclination of the will ministers to charity.’ This is the most
cited ‘Thomist’ axiom. He formulates it early in his career as
follows: ‘the gifts of grace are conferred on nature in such a way
that they do not destroy it but rather perfect it’. In fact, the axiom is
not exclusively or even particularly characteristic of Thomas. On
the contrary, the earliest recorded appearance is to be found in
Bonaventure, dated to 1248. The roots of the axiom lie in Greek
patristic theology, communicated through Dionysius and well
established in the West long before Thomas. Some Christians,
including Catholics, regard human reasoning as much too twisted
by human sinfulness to be easily fulfilled in Christian faith, just as
they are inclined to regard the Christian practice of charity as
cutting across the natural desires of human will. To such
Christians, the harmonious interaction between faith and reason,
charity and natural love, and thus between grace and nature, that is
expected by Thomas remains deeply problematic.
Summa
Theologiae
:
First

Theology in the university
The first thesis in the first question of the first part of the Summa
runs as follows: ‘The philosophical disciplines provide such a
complete account of everything, including the deity, that any other
kind of teaching seems superfluous’ (ST 1.1.1). The right of
Christian theology to count as a university discipline may well
require justification today. In an academic environment
dominated by the Catholic Church, Thomas could not be serious
(we might think) in questioning the need for any teaching about
God other than the disciplinae philosophicae. By the ‘philosophical
disciplines’ Thomas meant the whole range of the liberal arts,
mathematics, astronomy, the natural sciences, metaphysics, law,
medicine, and so on. This was all undergoing radical revision, as
the newly translated legacy of ancient Greece, mediated largely
through Muslim scholarship, was being assimilated. By no means a
universally welcomed process, the discovery that things in the
natural world, including human beings, could be studied on their
own, independently of biblical revelation and Church teaching,
threatened traditional Catholic orthodoxy. Some prominent
academics in the newly developing arts faculty at Paris seem to
have been exhilarated at the prospect. ‘All regions of reality’,
Thomas says, formulating the argument, ‘are dealt with in the
philosophical disciplines, including the divine – which is why the
Philosopher [Aristotle] refers to one part of philosophy as theology
or divine science’ (ST 1.1 objection 2): ‘There was no need for any
other kind of teaching.’
The new learning seemed to be developing into an alternative to
Catholicism, among members of the arts faculty, or so it was
suspected by the theologians. Boethius of Dacia (Bo of Denmark:
fl. 1275), in his book On the Highest Good, defended the possibility
of achieving beatitude through love of wisdom. He was assumed to
be influenced by Ibn Rushd’s version of Aristotle’s ideal of the
philosophic life as the way to supreme happiness. (He remained a
Thomas
Aquinas
34
Christian and eventually became a Dominican friar.) The Summa
Theologiae might have been composed (though we don’t know) to
persuade admirers of Aristotle that his philo sophia, ‘love of
wisdom’, was not only quite compatible with Christian
assumptions about nature, truth, goodness, and the soul, but
actually greatly illuminated them. Thomas did once say that
philosophy is a kind of revelation: ‘the study of philosophy is in its
own right allowable and praiseworthy, because God revealed to the
philosophers the truth which they perceive, as the Apostle [Paul]
says’ (ST 2/2.167.1).
On the other hand, in one of his last sermons at the University of
Paris, he said this: ‘A little old lady (vetula) of today knows more
about things concerning the faith than all the philosophers of
antiquity’ – quite a significant remark (we might think) to his
assembled colleagues and students at the height of the crisis over
the effects on Catholic Christian doctrine of the study of the pagan
Aristotle. He said much the same thing in a sermon on the Creed
preached probably in Naples in 1273: ‘None of the philosophers
before the coming of Christ was able, with all his effort on the task,
to know as much about God . . . as a little old lady knows, after the
coming of Christ, through her faith.’
Moreover, Thomas sees two ways of judging the right thing to say
or think in matters of Christian doctrine: one acquired by study,
the other ‘by experiencing the divine’, pati divina, in a neat phrase
quoted from Dionysius the Areopagite (ST 1.1.6).
Thomas distinguishes between theology (such as Aristotle’s)
achieved by the light of natural reason, and ‘holy teaching’, sacra
doctrina, based on faith in ‘sacred scripture’, sacra scriptura.
Human beings are called to a destiny (he assumes) that transcends
our natural capacities to discover:
We must know what the end is before we direct our intentions and
actions towards it. Therefore, it is necessary for human salvation
