People too often tolerate uncertainty prior to taking action; worse, some people believe that omniscience or infallibility are prerequisites for being certain, so they conclude that certainty (and therefore knowledge) is never possible. To any person who proclaims that "you can never be certain of anything", ask them: "are you sure?" and watch what happens.

The laws of men are not infallible.

A common fallacy in much of the adverse criticism to which science is subjected today is that it claims certainty, infallibility and complete emotional objectivity. It would be more nearly true to say that it is based upon wonder, adventure and hope.

I promise nothing complete; because any human thing supposed to be complete, must not for that very reason infallibly be faulty.

If he is infinitely good, what reason should we have to fear him? If he is infinitely wise, why should we have doubts concerning our future? If he knows all, why warn him of our needs and fatigue him with our prayers? If he is everywhere, why erect temples to him? If he is just, why fear that he will punish the creatures that he has filled with weaknesses? If grace does everything for them, what reason would he have for recompensing them? If he is all-powerful, how offend him, how resist him? If he is reasonable, how can he be angry at the blind, to whom he has given the liberty of being unreasonable? If he is immovable, by what right do we pretend to make him change his decrees? If he is inconceivable, why occupy ourselves with him? IF HE HAS SPOKEN, WHY IS THE UNIVERSE NOT CONVINCED?

One of the strangest phenomena of our time, and one that will probably be a matter of astonishment to our decedents, is that doctrine which is founded upon this triple hypothesis: the radical passiveness of mankind, -the omnipotence of the law, -the infallibility of the legislature: this is the sacred symbol of the party that proclaims itself exclusively democratic.

We aren’t encouraged to think for ourselves and ask questions. We are expected to accept what they teach us as infallible truths.

The Bible did not arrive by fax from heaven. The Bible is the product of man, my dear. Not of God. The Bible did not fall magically from the clouds. Man created it as a historical record of tumultuous times, and it has evolved through countless translations, additions, and revisions. History has never had a definitive version of the book.
