Doubt Quotes

“Persecution always says, 'I know the consequences of your opinion better than you know them yourselves.' But the language of toleration was always amicable, liberal, and just: it confessed its doubts, and acknowledged its ignorance ... Persecution had always reasoned from cause to effect, from opinion to action, [that such an opinion would invariably lead to but one action], which proved generally erroneous; while toleration led us invariably to form just conclusions, by judging from actions and not from opinions.”

“More than an end to war, we want an end to the beginnings of all wars. Yes, an end to this brutal, inhuman and thoroughly impractical method of settling the differences between Governments. The once powerful malignant Nazi state is crumbling; the Japanese warlords are receiving in their homelands the retribution for which they asked when they attacked Pearl Harbor. But the mere conquest of our enemies is not enough; we must go on to do all in our power to conquer the doubts and the fears, the ignorance and the greed, which made this horror possible.”

And when he is pretty darn sure of what the result is going to be, he is still in some doubt.

Scientific knowledge is a body of statements of varying degrees of certainty - some most unsure, some nearly sure, but none absolutely certain.”

“I am sorry they began their deliberations by so abominable a precedent as that of tying up the tongues of their members. Nothing can justify this example but the innocence of their intentions and ignorance of the value of public discussions. I have no doubt that all their other measures will be good and wise. It is really an assembly of demigods.”

“Another of the qualities of science is that it teaches the value of rational thought, as well as the importance of freedom of thought; the positive results that come from doubting that all the lessons are true... Learn from science that you must doubt the experts. As a matter of fact, I can also define science another way: Science is the belief in the ignorance of experts.”
