So bound up is the life of St. Thomas Aquinas with the thirteenth century that
the year in which the century reached its mid-point, 1250, was likewise the
mid-point of Thomas' life, though he was only twenty-five years old at the time
and still sitting at the feet of Albertus Magnus as a student in the Monastery
of the Holy Cross in Cologne. The thirteenth century has been called the
specifically "Occidental" century. The significance of this epithet
has not always been completely clarified, but in a certain sense I too accept
the term. I would even assert that the special quality of "Occidentality"
was ultimately forged in that very century, and by Thomas Aquinas himself. It
depends, however, on what we understand by "OccidentaIity." We shall
have more to say on this matter.
There exists the romantic notion that the thirteenth century was an era of
harmonious balance, of stable order, and of the free flowering of Christianity.
Especially in the realm of thought, this was not so. The Louvain historian
Fernand van Steenberghen speaks of the thirteenth century as a time of
"crisis of Christian intelligence";  and Gilson comments:
"Anybody could see that a crisis was brewing." 
What, in concrete terms, was the situation? First of all we must point out that
Christianity, already besieged by Islam for centuries, threatened by the
mounted hordes of Asiatics (1241 is the year of the battle with the Mongols at
Liegnitz)—that this Christianity of the thirteenth century had been
drastically reminded of how small a body it was within a vast non-Christian
world. It was learning its own limits in the most forceful way, and those
limits were not only territorial. Around 1253 or 1254 the court of the Great
Khan in Karakorum, in the heart of Asia, was the scene of a disputation of two
French mendicant friars with Mohammedans and Buddhists. Whether we can conclude
that these friars represented a "universal mission sent forth out of
disillusionment with the old Christianity,"  is more than questionable.
But be this as it may, Christianity saw itself subjected to a grave challenge,
and not only from the areas beyond its territorial limits.
For a long time the Arab world, which had thrust itself into old Europe, had
been impressing Christians not only with its military and political might but
also with its philosophy and science. Through translations from the Arabic into
Latin, Arab philosophy and Arab science had become firmly established in the
heart of Christendom—at the University of Paris, for example. Looking
into the matter more closely, of course, we are struck by the fact that Arab
philosophy and science were not Islamic by origin and character. Rather,
classical ratio, epitomized by Aristotle, had by such strangely
involved routes come to penetrate the intellectual world of Christian Europe.
But in the beginning, at any rate, it was felt as something alien, new, dangerous,
During this same period, thirteenth-century Christendom was being shaken
politically from top to bottom. Internal upheavals of every sort were brewing.
Christendom was entering upon the age "in which it would cease to be a
theocratic unity,"  and would, in fact, never be so again. In 1214 a
national king (as such) for the first time won a victory over the Emperor (as
such) at the Battle of Bouvines. During this same period the first religious
wars within Christendom flared up, to be waged with inconceivable cruelty on
both sides. Such was the effect of these conflicts that all of southern France
and northern Italy seemed for decades to be lost once and for all to the corpus
of Christendom. Old monasticism, which was invoked as a spiritual counterforce,
seems (as an institution, that is to say, seen as a whole) to have become
impotent, in spite of all heroic efforts to reform it (Cluny, Citeaux, etc.).
And as far as the bishops were concerned—and here, too, of course, we are
making a sweeping statement—an eminent Dominican prior of Louvain, who
incidentally may have been a fellow pupil of St. Thomas under Albertus Magnus
in Cologne, wrote the following significant homily: In 1248 it happened at
Paris that a cleric was to preach before a synod of bishops; and while he was
considering what he should say, the devil appeared to him. "Tell them this
alone," the devil said. "The princes of infernal darkness offer the
princes of the Church their greetings. We thank them heartily for leading their
charges to us and commend the fact that due to their negligence almost the
entire world is succumbing to darkness." 
But of course it could not be that Christianity should passively succumb to
these developments. Thirteenth-century Christianity rose In Its own defense,
and in a most energetic fashion. Not only were great cathedrals built in that
century; It saw also the founding of the first universities. The universities
undertook, among other things, the task of assimilating classical ideas and philosophy,
and to a large extent accomplished this task.
There was also the whole matter of the "mendicant orders," which
represented one of the most creative responses of Christianity. These new
associations quite unexpectedly allied !hemselves with the institution of the
university. The most important university teachers of the century, in Paris as
well as in Oxford, were all monks of the mendicant orders. All in all, nothing
seemed to be "finished"; everything had entered a state of flux.
AIbertus Magnus voiced this bold sense of futurity in the words: Scientiae
demonstrativae non omnes factae sunt, sed plures restant adhuc inveniendae; most of what exists in the realm of knowledge
remains still to be discovered. 
The mendicant orders took the lead in moving out into the world beyond the
frontiers of Christianity. Shortly after the nuddle of the century, while
Thomas was writing his Summa Against the Pagans, addressed to the mahumetistae et pagani,  the Dominicans were founding the first
Christian schools for teaching the Arabic language. I have already spoken of
the disputation between the mendicant friars and the sages of Eastern faiths in
Karakorum. Toward the end of the century a Franciscan translated the New
Testament and the Psalms into Mongolian and presented this translation to the
Great Khan. He was the same Neapolitan, John of Monte Corvino, who built a
church alongside the Impenal Palace in Peking and who became the first
Archbishop of Peking.
This mere listing of a few events, facts, and elements should make it clear
that the era was anything but a harmonious one. There is little reason for
wishing for a return to those times—aside from the fact that such wishes
are in themselves foolish.
Nevertheless, it may be said that in terms of the history of thought this
thirteenth century, for all its polyphonic character, did attain something like
harmony and "classical fullness." At least this was so for a period
of three or four decades. Gilson speaks of a kind of "serenity." 
And although that moment in time is of course gone and cannot ever again be
summoned back, it appears to have left its traces upon the memory of Western
Christianity, so that it is recalled as something paradigmatic and exemplary, a
kind of ideal spirit of an age which men long to see realized once more,
although under changed conditions and therefore, of course, in some altogether
Now as it happens, the work of Thomas Aquinas falls into that brief historical
moment. Perhaps it may be said that his work embodies that moment. Such, at any
rate, is the sense in which St. Thomas' achievement has been understood in the
Christian world for almost seven hundred years; such are the terms in which it
has repeatedly been evaluated. Not by all, to be sure (Luther called Thomas
"the greatest chatterbox" among the scholastic theologians ); but
the voices of approbation and reverence have always predominated. And even
aside from his written work, his personal destiny and the events of his life
unite virtually all the elements of that highly contradictory century in a kind
of "existential" synthesis. We shall now speak of these matters at
greater length, and in detail.
First of all, a few remarks regarding books.
The best introduction to the spirit of St. Thomas is, to my mind, the small
book by G. K. Chesterton, St. Thomas Aquinas.  This is not a scholarly work in the proper
sense of the word; it might be called journalistic—for which reason I am
somewhat chary about recommending it. Maisie Ward, co-owner of the British-American
publishing firm which publishes the book, writes in her biography of Chesterton
 that at the time her house published it, she was seized by a slight
anxiety. However, she goes on to say, Etienne Gilson read it and commented:
"Chesterton makes one despair. I have been studying St. Thomas all my life
and I could never have written such a book." Still troubled by the
ambiguity of this comment, Maisie Ward asked Gilson once more for his verdict
on the Chesterton book. This time he expressed himself in unmistakable terms:
"I consider it as being, without possible comparison, the best book ever
written on St. Thomas. . . . Everybody will no doubt admit that it is a
'clever' book, but the few readers who have spent twenty or thirty years in
studying St. Thomas Aquinas, and who, perhaps, have themselves published two or
three volumes on the subject, cannot fail to perceive that the so-called 'wit'
of Chesterton has put their scholarship to shame. . . . He has said all that
which they were more or less clumsily attempting to express in academic
formulas." Thus Gilson. I think this praise somewhat exaggerated; but at
any rate I need feel no great embarrassment about recommending an
