The heavy armor becomes the light dress of childhood; the pain is brief, the joy unending.

To expect a man to retain everything that he has ever read is like expecting him to carry about in his body everything that he has ever eaten.

Shame on such a morality that is worthy of pariahs, and that fails to recognize the eternal essence that exists in every living thing, and shines forth with inscrutable significance from all eyes that see the sun!

Reading is merely a surrogate for thinking for yourself; it means letting someone else direct your thoughts. Many books, moreover, serve merely to show how many ways there are of being wrong, and how far astray you yourself would go if you followed their guidance. You should read only when your own thoughts dry up, which will of course happen frequently enough even to the best heads; but to banish your own thoughts so as to take up a book is a sin against the holy ghost; it is like deserting untrammeled nature to look at a herbarium or engravings of landscapes.

Life is a constant process of dying.

In youth it is the outward aspect of things that most engages us; while in age, thought or reflection is the predominating qualityof the mind. Hence, youth is the time for poetry, and age is more inclined to philosophy. In practical affairs it is the same: a man shapes his resolutions in youth more by the impression that the outward world makes upon him; whereas, when he is old, it is thought that determines his actions.

After your death you will be what you were before your birth.
