“Berkeley retains the merit of having shown that the existence of matter is capable of being denied without absurdity.”

“Government can easily exist without laws, but law cannot exist without government.”

“The root of the matter is a very simple and old fashioned thing... love or compassion. If you feel this, you have a motive for existence, a guide for action, a reason for courage, an imperative necessity for intellectual honesty.”

“Language serves not only to express thought but to make possible thoughts which could not exist without it.”
