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

-Bertrand Russell
Bertrand Russell

If you think your belief is based upon reason, you will support it by argument rather than by persecution, and will abandon it if the argument goes against you. But if your belief is based upon faith, you will realize that argument is useless, and will therefore resort to force either in the form of persecution or by stunting or distorting the minds of the young in what is called 'education.'

Bertrand Russell
A widespread belief is more often likely to be foolish than sensible.
Bertrand Russell

In the visible world, the Milky Way is a tiny fragment; within this fragment, the solar system is an infinitesimal speck, and of this speck our planet is a microscopic dot. On this dot, tiny lumps of impure carbon and water, of complicated structure, with somewhat unusual physical and chemical properties, crawl about for a few years, until they are dissolved again into the elements of which they are compounded.

Bertrand Russell
You could take up the line that some of the gnostics took up - a line which I often thought was a very plausible one - that as a matter of fact this world that we know was made by the devil at a moment when God was not looking. There is a good deal to be said for that, and I am not concerned to refute it.
Bertrand Russell

Obscenity is whatever happens to shock some elderly and ignorant magistrate.

Bertrand Russell
I can only say that, while my own opinions as to ethics do not satisfy me, other people's satisfy me still less.
Bertrand Russell

It is a natural propensity to attribute misfortune to someone's malignity.

Bertrand Russell
He will see himself and life and the world as truly as our human limitations will permit; realizing the brevity and minuteness of human life, he will realize also that in individual minds is concentrated whatever of value the known universe contains.
Bertrand Russell

Those who advocate common usage in philosophy sometimes speak in a manner that suggests the mystique of the 'common man.'

Bertrand Russell
If the West can claim superiority in anything, it is . . . in science and scientific technique.
