Bertrand Russell (1872 - 1970) was a British philosopher, mathematician, and writer, Nobel laureate in literature.
I would never die for my beliefs because I might be wrong.
Bertrand Russell
It has been said that man is a rational animal. All my life I have been searching for evidence which could support this.
Bertrand Russell
It is a waste of energy to be angry with a man who behaves badly, just as it is to be angry with a car that won't go.
Bertrand Russell
The greatest challenge to any thinker is stating the problem in a way that will allow a solution.
Bertrand Russell
Not to be absolutely certain is, I think, one of the essential things in rationality.
Bertrand Russell
When one admits that nothing is certain one must, I think, also admit that some things are much more nearly certain than others. It is much more nearly certain that we are assembled here tonight than it is that this or that political party is in the right. Certainly there are degrees of certainty, and one should be very careful to emphasize that fact, because otherwise one is landed in an utter skepticism, and complete skepticism would, of course, be totally barren and completely useless.
Bertrand Russell
Man is a credulous animal, and must believe something; in the absence of good grounds for belief, he will be satisfied with bad ones.
