We have almost reached the point where praise of rationality is held to mark a man as an old fogey regrettably surviving from a bygone age.

-Bertrand Russell
Bertrand Russell

To teach how to live without certainty and yet without being paralysed by hesitation is perhaps the chief thing that philosophy, in our age, can do for those who study it.

Bertrand Russell
It is no credit to the orthodox that they do not now believe all the absurdities that were believed 150 years ago. The gradual emasculation of the Christian doctrine has been effected in spite of the most vigorous resistance, and solely as the result of the onslaughts of freethinkers.
Bertrand Russell

Truth is a shining goddess, always veiled, always distant, never wholly approachable, but worthy of all the devotion of which the human spirit is capable.

Bertrand Russell
I say people who feel they must have a faith or religion in order to face life are showing a kind of cowardice, which in any other sphere would be considered contemptible. But when it is in the religious sphere it is thought admirable, and I cannot admire cowardice whatever sphere it is in.
Bertrand Russell

Calculus required continuity, and continuity was supposed to require the infinitely little; but nobody could discover what the infinitely little might be.

Bertrand Russell
The habit of looking to the future and thinking that the whole meaning of the present lies in what it will bring forth is a pernicious one. There can be no value in the whole unless there is value in the parts.
Bertrand Russell

William James used to preach the "will-to-believe." For my part, I should wish to preach the "will-to-doubt." None of our beliefs are quite true; all at least have a penumbra of vagueness and error. What is wanted is not the will to believe, but the will to find out, which is the exact opposite.

Bertrand Russell
The fact that all Mathematics is Symbolic Logic is one of the greatest discoveries of our age; and when this fact has been established, the remainder of the principles of mathematics consists of the analysis of Symbolic Logic itself.
Bertrand Russell

It is, of course, clear that a country with a large foreign population must endeavour, through its schools, to assimilate the children of immigrants. It is, however, unfortunate that a large part of this process should be effected by means of a somewhat blatant nationalism.

Bertrand Russell
Formality Thus the absence of all mention of particular things or properties in logic or pure mathematics is a necessary result of the fact that this study is, as we say, "purely formal".
