“But then arises the doubt, can the mind of man, which has, as I fully believe been developed from a mind as low as that possessed by the lowest animal, be trusted when it draws such grand conclusions?”

“But then with me the horrid doubt always arises whether the convictions of man's mind, which has been developed from the mind of the lower animals, are of any value or at all trustworthy. Would any one trust in the convictions of a monkey's mind, if there are any convictions in such a mind?[To William Graham 3 July 1881]”

“The mind of the dreaming man is fully satisfied with whatever happens to it. The agonizing question of possibility does not arise.”

“The mind which is most capable of receiving impressions is very often the least capable of drawing conclusions.”

“True emptiness is not empty, but contains all things. The mysterious and pregnant void creates and reflects all possibilities. From it arises our individuality, which can be discovered and developed, although never possessed or fixed.”

“He who is in love is wise and is becoming wiser, sees newly every time he looks at the object beloved, drawing from it with his eyes and his mind those virtues which it possesses.”
