If the advice of a fool for once happens to be good, it requires a wise man to carry it out.

The superstition in which we were brought up never loses its power over us, even after we understand it.

Why should not every individual man have existed more than once upon this world? Why should I not come back as often as I am capable of acquiring fresh knowledge? Is this hypothesis so laughable merely because it is the oldest? Because the human understanding, before the sophistries of the schools had dissipated and debilitated it, lighted upon it at once?

Pleasures, riches, honor and joy are sure to have care, disgrace, adversity and affliction in their train. There is no pleasure without pain, no joy without sorrow. O the folly of expecting lasting felicity in a vale of tears, or a paradise in a ruined world.

The true value of man is not determined by his possession, supposed or real, of Truth, but rather by his sincere exertion to get to the Truth. It is not possession of Truth by which he extends his powers and in which his ever-growing perfectability is to be found. Possession makes one passive, indolent and proud. If God were to hold all Truth concealed in his right hand, and in his left only the steady and diligent drive for Truth, albeit with the proviso that I would always and forever err in the process, and to offer me the choice, I would with all humility take the left hand.

Absolute truth belongs to Thee alone.

He who doesn't lose his wits over certain things has no wits to lose.
