Often described as the last great work of Western classical antiquity, Boethius' Consolation of Philosophy grapples with many of the enduring questions in philosophy; the problem of evil, determinism vs. free-will and nature of virtue and justice, among others. Though a committed Christian, Boethius arrives at his conclusions by means of the natural philosophical methods of Classical Greece alone, being of the opinion that faith and reason must necessarily arrive at the same conclusions.
