A hallucination is a fact, not an error; what is erroneous is a judgment based upon it.
— Bertrand Russell
The Monist (Apr 1914), 24:2, 173.
Although this may seem a paradox, all exact science is dominated by the idea of approximation. When a man tells you that he knows the exact truth about anything, you are safe in infering that he is an inexact man. Every careful measurement in science is always given with the probable error ... every observer admits that he is likely wrong, and knows about how much wrong he is likely to be.
— Bertrand Russell
In The Scientific Outlook (1931, 2009), 42.
If the matter is one that can be settled by observation, make the observation yourself. Aristotle could have avoided the mistake of thinking that women have fewer teeth than men, by the simple device of asking Mrs. Aristotle to keep her mouth open while he counted.
— Bertrand Russell
In An Outline of Intellectual Rubbish (1943), 22.
Since the world is what it is, it is clear that valid reasoning from sound principles cannot lead to error; but a principle may be so nearly true as to deserve theoretical respect, and yet may lead to practical consequences which we feel to be absurd. There is therefore a justification for common sense in philosophy, but only as showing that our theoretical principles cannot be quite correct so long as their consequences are condemned by an appeal to common sense which we feel to be irresistible.
— Bertrand Russell
In A History of Western Philosophy, (1945, 1996), 553.
There are infinite possibilities of error, and more cranks take up fashionable untruths than unfashionable truths.
— Bertrand Russell
Principles of Social Reconstruction (1916). Also in An Outline of Intellectual Rubbish (1943), reprinted in Unpopular Essays (1950) and collected in 'An Outline of Intellectual Rubbish', The Basic Writings of Bertrand Russell (2009), 61.
Who ever heard a theologian preface his creed, or a politician conclude his speech with an estimate of the probable error of his opinion.
— Bertrand Russell
In The Scientific Outlook (1931, 1954), 66.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
