“Skepticism is the beginning of faith.”
“Conscious faith is freedom. Emotional faith is slavery. Mechanical faith is foolishness.”
“Most institutions demand unqualified faith; but the institution of science makes skepticism a virtue.”
“A foolish faith in authority is the worst enemy of truth.”
“The desire for a strong faith is not the proof of a strong faith, rather the opposite. If one has it one may permit oneself the beautiful luxury of skepticism: one is secure enough, fixed enough for it.”
