Context

“The Consolations, which Gibbon rightly calls a “ golden volume, ” begins by the statement that Socrates, Plato, and Aristotle are the true philosophers; Stoics, Epicureans, and the rest are usurpers, whom the profane multitude mistook for the friends of philosophy. Boethius says he obeyed the Pythagorean command to “ follow God ” (not the Christian command). Happiness, which is the same thing as blessedness, is the good, not pleasure. Friendship is a “ most sacred thing. ” There is a summary, in verse, of the beginning of the Timaeus. This is followed by a great deal of purely Platonic metaphysics. Imperfection, we are told, is a lack, implying the existence of a perfect pattern.” source
