Arthur Schopenhauer 
Religion: a Dialogue [EPUB ebook] 

Schopenhauer is one of the few philosophers who can be generally understood without a commentary. All his theories claim to be drawn direct from the facts, to be suggested by observation, and to interpret the world as it is; and whatever view he takes, he is constant in his appeal to the experience of common life. This characteristic endows his style with a freshness and vigor which would be difficult to match in the philosophical writing of any country, and impossible in that of Germany. If it were asked whether there were any circumstances apart from heredity, to which he owed his mental habit, the answer might be found in the abnormal character of his early education, his acquaintance with the world rather than with books, the extensive travels of his boyhood, his ardent pursuit of knowledge for its own sake and without regard to the emoluments and endowments of learning.
