“Supposing you knew — not by sight or by instinct, but by sheer intellectual knowledge, as I know the truth of a mathematical proposition — that what we call empty space was full, crammed.”

—  John Buchan

Space (1912)
Context: Supposing you knew — not by sight or by instinct, but by sheer intellectual knowledge, as I know the truth of a mathematical proposition — that what we call empty space was full, crammed. Not with lumps of what we call matter like hills and houses, but with things as real — as real to the mind.

“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; and let no day, if possible, pass away without some intellectual gain.”

“If you can’t show that it’s true, then you can’t call it truth. Knowledge is similar to truth in that it a justified belief. Knowledge is demonstrable and testable with measurable accuracy. If you can’t demonstrate your knowledge to any degree at all by any means whatsoever then you don’t actually know what you think you do, no matter how convinced of it you are. Without evidentiary support, then it is only an empty assertion unworthy of serious consideration.”

“The goodness and greatness of a man do not justify us in accepting a belief upon the warrant of his authority, unless there are reasonable grounds for supposing that he knew the truth of what he was saying. And there can be no grounds for supposing that a man knows that which we, without ceasing to be men, could not be supposed to verify.”

On Mahatma Gandhi<!-- p. 506 (1949) / p. 310 (1961) -->
Autobiography (1936; 1949; 1958)
Context: I knew that Gandhiji usually acts on instinct (I prefer to call it that than the "inner voice" or an answer to prayer) and very often that instinct is right. He has repeatedly shown what a wonderful knack he has of sensing the mass mind and of acting at the psychological moment. The reasons which he afterward adduces to justify his action are usually afterthoughts and seldom carry one very far. A leader or a man of action in a crisis almost always acts subconsciously and then thinks of the reasons for his action.
