‘The greatest and most significant philosopher of this period was St. Thomas Aquinas, who lived from 1225 to 1274. He came from the little town of Aquino, between Rome and Naples, but he also worked as a teacher at the University of Paris. I call him a philosopher but he was just as much a theologian. There was no great difference between philosophy and theology at that time. Briefly, we can say that Aquinas christianized Aristotle in the same way that St. Augustine christianized Plato in early medieval times.’
