“It is difficult to get a man to understand something, when his salary depends on his not understanding it.”
― Upton Sinclair, I, Candidate for Governor: And How I Got Licked

“In like manner, if I let myself believe anything on insufficient evidence, there may be no great harm done by the mere belief; it may be true after all, or I may never have occasion to exhibit it in outward acts. But I cannot help doing this great wrong towards Man, that I make myself credulous. The danger to society is not merely that it should believe wrong things, though that is great enough; but that it should become credulous, and lose the habit of testing things and inquiring into them; for then it must sink back into savagery.”
― William Kingdon Clifford, Ethics of Belief and Other Essays

“Every time we let ourselves believe for unworthy reasons, we weaken our powers of self-control, of doubting, of judicially and fairly weighing evidence. We all suffer severely enough from the maintenance and support of false beliefs and the fatally wrong actions which they lead to, and the evil born when one such belief is entertained is great and wide.”
― William Kingdon Clifford

“Let us understand, once for all, that the ethical progress of society depends, not on imitating the cosmic process, still less in running away from it, but in combating it.”
― Thomas Henry Huxley, Evolution and Ethics and Other Essays
