The Anatomy of Melancholy [EPUB ebook] 

The Anatomy of Melancholy, one of the richest, most inexhaustible books in the English language.
Ostensibly an elaborately systematized medical treatise dealing with various morbid mental states — their causes, symptoms, and cures — the Anatomy is much more: a compendium of memorable utterances on the human condition in general, compiled from classical, scholastic, and contemporary sources. For this edition, the editors carefully selected passages of the most psychological and general interest, eliminating the nonessential material but retaining the incomparable humor, eccentric charm, imagination, and thought-provoking appeal of the original.
