Boethius has a dialogue with the personification of philosophy about the fickleness of Fortuna. Philosophy walks the narrator through a series of reasoning, based largely upon the thinking of Plato, for accepting his imprisonment and impending death with grace.
The book is a prime example of the Platonic dialogue.
It is difficult to see a contemporary reader swallowing everything that is said. Outside of the world as presented on television during the 1950s and 1960s we do not live in a world in which the just get what they need and only the evil are meted out misfortune.
I would recommend this book, primarily as a piece of literature from another time.
