Scepticism quotes

I don't believe in astrology. I'm a Sagittarian and we're very sceptical.
Arthur C. Clarke

Better to be too sceptical than to be too trusting.
Chinese proverb

The problems of the world cannot possibly be solved by skeptics or cynics whose horizons are
limited by the obvious realities. We need men who can dream of things that never were.
John F. Kennedy

So I should say that civilizations begin with religion and stoicism: they end with scepticism
and unbelief, and the undisciplined pursuit of individual pleasure. A civilization is born stoic
and dies epicurean.
Will Durant

Blind belief in authority is the greatest enemy of truth.
Albert Einstein

The radical invents the views. When he has worn them out the conservative adopts them.
Mark Twain

People are not stupid. They believe things for reasons. The last way for skeptics to get the
attention of bright, curious, intelligent people is to belittle or condescend or to show
arrogance toward their beliefs.
Carl Sagan

Be skeptical, but learn to listen.
Don Miguel Ruiz

Men are never convinced of your reasons, of your sincerity, of the seriousness of your
sufferings, except by your death. So long as you are alive, your case is doubtful; you have a
right only to their skepticism.
Albert Camus

Do not let yourself be tainted with a barren skepticism.
Louis Pasteur

Those who can make you believe absurdities, can make you commit atrocities.

All great truths begin as blasphemies.
George Bernard Shaw

Tell people there's an invisible man in the sky who created the universe, and the vast majority
will believe you. Tell them the paint is wet, and they have to touch it to be sure.
George Carlin

Moral certainty is always a sign of cultural inferiority. The more uncivilized the man, the surer
he is that he knows precisely what is right and what is wrong. All human progress, even in
morals, has been the work of men who have doubted the current moral values, not of men
who have whooped them up and tried to enforce them. The truly civilized man is always
skeptical and tolerant.
H. L. Mencken

We wish to find the truth, no matter where it lies. But to find the truth we need imagination
and skepticism both. We will not be afraid to speculate, but we will be careful to distinguish
speculation from fact.
Carl Sagan

New opinions are always suspected, and usually opposed, without any other reason but
because they are not already common.
John Locke

The method of science is tried and true. It is not perfect, it's just the best we have. And to
abandon it with its skeptical protocols is the pathway to a dark age.
Carl Sagan

I much prefer the sharpest criticism of a single intelligent man to the thoughtless approval of
the masses.
Johannes Kepler

I know of no society in human history that ever suffered because its people became too
desirous of evidence in support of their core beliefs.
Sam Harris

Almost all really new ideas have a certain aspect of foolishness when they are first produced.
Alfred North Whitehead

In all the events of life, we ought still to preserve our scepticism. If we believe that fire
warms, or water refreshes, it is only because it costs us too much pains to think otherwise.
David Hume

Skepticism is the agent of reason against organized irrationalism - and is therefore one of the
keys to human social and civic decency.
Michael Shermer

Doubt everything or believe everything: these are two equally convenient strategies. With
either we dispense with the need for reflection.
Henri Poincare
