Disprove Quotes

Sharp thinking on evidence, bias, and what can't be proven wrong.

These quotes circle a single scientific habit: forming a theory, then trying as hard as possible to disprove it before trusting the result. That instinct shows up in remarks about atheism, unconscious bias, and skeptics demanding hard evidence before accepting a claim, echoing the reasoning found in our Accusation quotes page.

The existence of a single atheist does not disprove the existence of God.

Quotes by William F. DeVault

No one will presumably ever be able to prove or disprove such fundamental religious principles as the existence of God.

Quotes by Stephen Kinzer

Everyone - male and female - is biased. But no one wants to admit it, so our brains search for examples that disprove the accusation.

Quotes by Nell Scovell

Skeptics question the validity of a particular claim by calling for evidence to prove or disprove it.

Quotes by Michael Shermer

Able Quotes

You make observations, write theories to fit them, try experiments to disprove the theories and, if you can't, you've got something.

Quotes by Kary Mullis

The point of an experiment is not to arrive at a predetermined end point, to prove or disprove anything, but to deliver a poem that reveals much about the process taken.

Quotes by John Barton

You can't prove any hypothesis, you can only improve or disprove it.

Quotes by Christopher Monckton

Accusation Quotes

To succeed with the opposite sex, tell her you're impotent. She can't wait to disprove it.

Quotes by Cary Grant

Science should always be in the business of attempting to disprove itself.

Quotes by Ben Stein

Is it really true that religion makes people more kindly, generous, or loving? History tends to disprove this. The worst wars, the most vicious Inquisitions, the cruelest pogroms and persecutions, were both fomented and supported by religion.

Quotes by Barbara G. Walker

There's nothing in this country that is a worse accusation - in America, if you accuse somebody of racism, that person has to disprove that.

Quotes by Andrew Breitbart

Frequently Asked Questions

What philosophical point do these disprove quotes make?
Most argue that a single counterexample cannot invalidate a broader claim, as seen in the observation that one atheist existing does not disprove the existence of God. It is a point about logic more than belief itself.
Do any quotes connect disproving ideas to personal bias?
Yes, one notes that everyone carries bias but rarely admits it, so people's minds instinctively search for examples that disprove any accusation of being biased in the first place.
How is the scientific method described in these quotes?
One quote lays it out plainly: form observations, write a theory, then run experiments specifically designed to disprove that theory. If the theory survives those attempts, it is considered worth trusting.
What role does skepticism play in this quote collection?
Skepticism is treated as a demand for evidence rather than blind doubt. One quote describes skeptics as people who question claims specifically by asking for proof that can prove or disprove them.
Are these disprove quotes more scientific or philosophical?
They blend both. Some quotes describe formal scientific testing, while others make broader logical points about bias, belief, and what a single exception can or cannot demonstrate.

Together they make the case that a claim only earns credibility once it survives every honest attempt to knock it down. For more on doubt and evidence, see our Able quotes and Admit quotes collections.
