Quotes about doubt

You’re right to be skeptical—the world would be a better place if we were all a little less credulous.

The symbol of the University is the iron statue outside the Rathskeller of a barefoot goose girl that every student kisses at graduation. The University is a Mecca to which students come with something less than perfect faith. It is important that students bring a certain ragamuffin, barefoot irreverence to their studies; they are not here to worship what is known but to question it.

The progress of human knowledge depends on maintaining that touch of scepticism even about the most "unquestionable" truths. A century ago, Darwin's theory of evolution by natural selection was regarded as scientifically unshakeable; today, most biologists have their reservations about it. Fifty years ago, Freud's sexual theory of neurosis was accepted by most psychiatrists; today, it is widely recognized that his methods were highly questionable. At the turn of this century, a scientist who questioned Newton's theory of gravity would have been regarded as insane; twenty years later, it had been supplanted by Einstein's theory, although, significantly, few people actually understood it. It seems perfectly conceivable that our descendants of the twenty-second century will wonder how any of us could have been stupid enough to have been taken in by Darwin, Freud or Einstein.

People are riddled by Doubt. It is the engine that drives them through their lives. It is the elastic band in the little model airplane of their soul, and they spend their time winding it up until it knots. Early morning is the worst time—there's that little moment of panic in case You have drifted away in the night and something else has moved in. This never happened to Granny Weatherwax.

Doubt, Lady, is the chastity of the mind, and I bear its seal upon my own.

A time is marked not so much by ideas that are argued about as by ideas that are taken for granted. The character of an era hangs upon what needs no defense. Power runs with ideas that only the crazy would draw into doubt. The "taken for granted" is the test of sanity; "what everyone knows" is the line between us and them.

This means that sometimes a society gets stuck. Sometimes these unquestioned ideas interfere, as the cost of questioning becomes too great. In these times, the hardest task for social or political activists is to find a way to get people to wonder again about what we all believe is true. The challenge is to sow doubt.

Political commitment isn’t a perimeter, Sam; it’s a parameter. Don’t you ever wonder? Don’t you ever doubt?

I have learned yet again (this has been going on all my life) what folly it is to take any thing for granted without examining it skeptically.

When have you ever seen someone who had no doubts who was also correct about anything?

This is how humans are: We question all our beliefs, except for the ones that we really believe in, and those we never think to question.

“What do we know? What do we really know? He licks his dried cracked lips. We know this apodictic rock beneath our feet. That dogmatic sun above our heads. The world of dreams, the agony of love and the foreknowledge of death. That is all we know. And all we need to know? Challenge that statement. I challenge that statement. With what? I don't know.”
