HouserI expect to die in my bed, my successor will die in prison, and his successor will die a martyr in the public square. Then his successor will pick up the shards of a ruined society and slowly help rebuild civilization, as the Church has done so often in human history.—Francis Cardinal George (2010)Here I propose to (...) present a feature of the ethics of Thomas Aquinas, his ethical doctrine of virtue, concentrating on the four cardinal virtues—justice, prudence or good practical judgment, courage, and temperance. Plato first selected them as the four premier virtues, but they go back at least to Homer, for whom wily Odysseus exemplified prudence, warlike Achilles courage, old Nestor justice, Penelope and Telemachus, Odysseus' wife and son, temperance. And I offer them as central to living the morally good life required to "rebuild civilization" in an America that so fair and judicious a man as Cardinal George could call a "ruined society." To see the need for Thomas's solution, we must begin with the problem. Now, all societies depend upon the deep and fundamental ideas of the most important thinkers, prophets and sages, saints, and yes, even philosophers. Their ideas "trickle down" to influence regular folk, like you and me, those who whose hard work actually makes a society thrive, or die. And when those fundamental ideas change, the moral principles of those who embrace those ideas change, and consequently their actions change, and as a result the wider society in which they live changes, for better or worse. Such effects can now be felt across America [End Page 135] by all; but most of us are unaware of the primary intellectual agents of these changes, since they operate at the level of fundamental ideas, not politics or business or day-to-day life. And often their originators have died before the ideas reach full cultural force. So, ignorance of history makes it difficult to deal with present problems caused by those ideas.My first conclusion will be that a major cause of the current coarsening of our culture is the group of ideas of the French philosopher Jean Paul Sartre, even though most Americans have never heard of him, and most of those who recognize his name have not read his works carefully enough to see the connection. Why Sartre? In the honors program at my university, I had a bright young lady of Muslim heritage who had gone to a lycée, one of France's elite classical secondary schools. "Did you read the classics?" "Yes." Expecting Montaigne or Pascal, I asked, "Who?" Her answer: "Sartre." So let us begin with the theory and practice of Sartre and his long-time lover Simone Beauvoir, whose book The Second Sex was an intellectual spark for the women's liberation movement. Then we turn to some real-life examples of Sartrean influence on ourselves and American culture. Finally, for the best remedy for non-Christian and Christian alike, I recommend Aquinas's doctrine of virtue, when taken in its full scope.Sartre's Ethics of Absolute FreedomIn 1946, the year I was born, Sartre gave a lecture to a meeting of French librarians, which became his most popular book, Existentialism is a Humanism. There he laid out the core of his thought about God, humans, and their ethical behavior. Here I arrange his main ideas in an order that facilitates comparison with Aquinas, beginning with his view of human ontology and proceeding to its impact on the four cardinal virtues.Human OntologySartre turned his back on the traditional metaphysical view that every creature is an individual substance defined by a nature or essence it has in common with all other things of that type. In his "first principle of existentialism," Sartre skips over other animate things, plants and animals, and compares humans to inanimate objects:Let us consider... a book or a paper-cutter: here is an object made by an artisan whose inspiration came from a concept.... One cannot postulate a man who makes a paper-cutter but does not know what it is... (shrink)

Aquinas’s theology, as presented in his Scriptum, is “scientific” in the Aristotelian sense of this term. Some of its arguments for conclusions are based on theology’s “proper” principles—the articles of faith—but many others are purely rational demonstrations. As the basis for his rational arguments in theology, and in particular his treatment of the divine essence in d. 8, he introduces philosophical principles, and offers dialectical arguments for them, which are thoroughly Avicennian. In order to understand Aquinas’s commentary on d. 8, (...) then, it is not just helpful but necessary to see how he makes use of doctrines coming from the Metaphysics of Avicenna’s Book of Healing. So we look first at Aquinas’s source texts in Avicenna, and then at how he makes use of them in his commentary on the Sentences, Bk. 1, d. 8. (shrink)

Here, I should like to tell a story, beginning with how the works of Aristotelian philosophy came to exist in Latin translations, then moving to the project of transforming Christian theology into an Aristotelian “science.” After that, I would like to look a bit more closely at the case of Br. Thomas of Aquino and his dependence upon the Muslim philosopher Ibn Sīnā. Finally, I shall end by drawing some wider conclusions based upon this important example.
