To my knowledge only a threesome of authors (Sartre, Nietzsche and Macchiavelli) would have been able as well as to tell "useful" words on this combination of topics Aquinas chose. The author - few are more original than Thomas - looks back on, examines some of the most basic, important questions that interest humanity (human nature and ethics, politics and law...) and explores them in the light of Christian faith, as well as ancient philosophy. Of the 'ancients" he looks in particular close to Aristotle, whom's version of the Bible was of till then. So one could say that he was sort of a predecessor for the great humanists... Aquinas tries to restore the autonomy of nature and reason, in full harmony with (Christian) faith. The result of his work is genial, both what concerns the scholastic ànd "thomistic" style as well as for the special way of exploring and investigating through which he succeeds to "restore in faith". Everyone who wants to read Aquinas should know that the author writes in a very specific, difficult way. It looks from time to time he opposes to himself, but after studying his readings one can only conclude that this is REAL top-of-the-shelf literature (for those esp. who like theology, philosophy, politics, ...).
