 The third book originally consisted of forty-two chapters, and the fourth of fifty-eight.These two books, like the larger part of the second, treat of ethics; the third, of virtues and vices, in pairs; the fourth, of more general ethical and political subjects, frequently citing extracts to illustrate the pros and cons of a question in two successive chapters.The first edition of books 1 and 2 was that by G. Canter (Antwerp, 1575).
