A hallucination is a fact, not an error; what is erroneous is a judgment based upon it. Bertrand Russel

I cannot favour laws such as that of Idaho, which allows sterilization of 'mental defectives, epileptics, habitual criminals, moral degenerates, and sex perverts.' The last two categories here are very vague . . . The law of Idaho would have justified the sterilization of Socrates, Plato, Julius Caesar, and St. Paul.

All movements go too far.
Bertrand Russell

Really high-minded people are indifferent to happiness, especially other people's.

Bertrand Russell
It is not what the man of science believes that distinguishes him, but how and why he believes it. His beliefs are tentative, not dogmatic; they are based on evidence, not on authority or intuition.
Bertrand Russell

A happy life must be to a great extent a quiet life, for it is only in an atmosphere of quiet that true joy dare live.

Bertrand Russell
Christ . . . said that a man who had looked after a woman lustfully had sinned as much as the man who had seduced her. How absurd!
Bertrand Russell

Much of the most important evils that mankind have to consider are those which they inflict upon each other through stupidity or malevolence or both.

Bertrand Russell
Man can be scientifically manipulated.
Bertrand Russell

Mathematics is, I believe, the chief source of the belief in eternal and exact truth, as well as a sensible intelligible world.

Bertrand Russell
A physicist looks for causes; that does not necessarily imply that there are causes everywhere. A man may look for gold without assuming that there is gold everywhere; if he finds gold, well and good, if he doesn't he's had bad luck. The same is true when the physicists look for causes.
