“We may believe the statement of another person, when there is reasonable ground for supposing that he knows the matter of which he speaks, and that he is speaking the truth so far as he knows it.”

— William Kingdon Clifford

The Ethics of Belief (1877), The Limits Of Inference
Context: p>We may believe what goes beyond our experience, only when it is inferred from that experience by the assumption that what we do not know is like what we know. We may believe the statement of another person, when there is reasonable ground for supposing that he knows the matter of which he speaks, and that he is speaking the truth so far as he knows it.It is wrong in all cases to believe on insufficient evidence; and where it is presumption to doubt and to investigate, there it is worse than presumption to believe.</p

“A person is strong only when he stands upon his own truth, when he speaks and acts from his deepest convictions. Then, whatever the situation he may be in, he always knows what he must say and do. He may fall, but he cannot bring shame upon himself or his cause.”

Mikhail Bakunin book God and the State

God and the State (1871; publ. 1882)
Context: A person is strong only when he stands upon his own truth, when he speaks and acts from his deepest convictions. Then, whatever the situation he may be in, he always knows what he must say and do. He may fall, but he cannot bring shame upon himself or his cause. If we seek the liberation of the people by means of a lie, we will surely grow confused, go astray, and lose sight of our objective, and if we have any influence at all on the people we will lead them astray as well — in other words, we will be acting in the spirit of reaction and to its benefit.

“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.”

William Kingdon Clifford (1845–1879) English mathematician and philosopher

Over the obscure man is poured the merciful suffusion of darkness. None knows where he goes or comes. He may seek the truth and speak it; he alone is free; he alone is truthful, he alone is at peace.
