“Knowledge is always a legitimating idea, in the sense that assertions of knowledge always assert what is correct, what is proper, what is legitimate. If any explanatory or causal statement is accepted as knowledge, then it is accepted as an aspect of truth, and as a basis for reason, for rational action, where knowledge, truth and reason are all interrelated, legitimating ideas.”

“Hegel said that `truth` is subjective, thus rejecting the existence of any `truth` above or beyond human reason. All knowledge is human knowledge.”

“Knowledge is power. Power in the aspect of making your own mind up;and, not accepting what others tell you.”

“It is meaningless to speak in the name of - or against - Reason, Truth, or Knowledge.”

“Science is organized knowledge. Wisdom is organized life.”

“Once a day, especially in the early years of life and study, call yourselves to an account what new ideas, what new proposition or truth you have gained, what further confirmation of known truths, and what advances you have made in any part of knowledge.”

“Our knowledge is a receding mirage in an expanding desert of ignorance.”
