Carl Sagan·1996The truth may be puzzling. It may take some work to grapple with. It may be counterintuitive. It may contradict deeply held prejudices. It may not be consonant with what we desperately want to be true. But our preferences do not determine what's true. We have a method, and that method helps us to reach not absolute truth, only asymptotic approaches to the truth — never there, just closer and closer, always finding vast new oceans of undiscovered possibilities. Cleverly designed experiments are the key.
Maimonides·1190Every Israelite has a duty to study whether he is poor or rich, whether healthy or suffering, whether young or very old and in failing strength, even if he is poor and supported by charity or begs from door to door.
Francis Bacon·1620Truth is the daughter of time, not of authority.
