Sin is geographical. Bertrand Russel
It's easy to fall in love. The hard part is finding someone to catch you.
Suppose atomic bombs had reduced the population of the world to one brother and sister; should they let the human race die out?
The practice of inhibiting impulses, which is to a great extent necessary to civilized life, makes mistakes easier, by preventing experience of the actions to which a desire would otherwise lead, and by often causing the inhibited impulses themselves to be unnoticed or quickly forgotten.
I did not, however, commit suicide, because I wished to know more of mathematics.
The first essential character [of civilization], I should say, is forethought. This, I would say, is what distinguishes men from brutes and adults from children.
It is only through imagination that men become aware of what the world might be; without it, â€˜progressâ€™ would become mechanical and trivial.
Nothing of importance is ever achieved without discipline. I feel myself sometimes not wholly in sympathy with some modern educational theorists, because I think that they underestimate the part that discipline plays. But the discipline you have in your life should be one determined by your own desi
Not to be absolutely certain is, I think, one of the essential things in rationality.
Certain characteristics of the subject are clear. To begin with, we do not in this subject deal with particular things or particular properties: we deal formally with what can be said about any thing or any property. We are prepared to say that one and one are two, but not that Socrates and Plato ar
Modern life cannot be constructed on . . . physically strenuous principles. A great deal of work is sedentary, and most manual work exercises only a few specialized muscles.
There is an element of the busybody in our conception of virtue: unless a man makes himself a nuisance to a great many people, we do not think he can be an exceptionally good man.
A life devoted to science is therefore a happy life, and its happiness is derived from the very best sources that are open to dwellers on this troubled and passionate planet.
Science, in its ultimate ideal, consists of a set of propositions arranged in a hierarchy, the lowest level of the hierarchy being concerned with particular facts, and the highest with some general law, governing everything in the universe. The various levels in the hierarchy have a two-fold logical
If a philosophy is to bring happiness it should be inspired by kindly feelings. Marx pretended that he wanted the happiness of the proletariat; what he really wanted was the unhappiness of the bourgeois.
The atomists , unlike Socrates , Plato , and Aristotle , sought to explain the world without introducing the notion of purpose or final cause.
Every living thing is a sort of imperialist, seeking to transform as much as possible of its environment into itself.
It seems to us unwise to have insisted on teaching geometry to the younger Dionysius, tyrant of Syracuse, in order to make him a good king, but from Plato's point of view it was essential. He was sufficiently Pythagorean to think that without mathematics no true wisdom is possible.
The only thing that will redeem mankind is cooperation ... it is common to wish well to oneself, but in our technically unified world, wishing well to oneself is sure to be futile unless it is combined with wishing well to others.
My first advice on how not to grow old would be to choose you ancestors carefully.
Is the set of all sets which are not members of themselves a member of itself?
To fear love is to fear life, and those who fear life are already three parts dead.
To be happy in this world, especially when youth is past, it is necessary to feel oneself not merely an isolated individual whose day will soon be over, but part of the stream of life slowing on from the first germ to the remote and unknown future.
It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living.
When a man tells you that he knows the exact truth about anything you are safe in inferring that he is an inexact man.
I am compelled to fear that science will be used to promote the power of dominant groups rather than to make men happy.
Religion is based, I think, primarily and mainly upon fear.
As men begin to grow civilized, they cease to be satisfied with mere taboos.
Envy is the basis of democracy.
The first effect of emancipation from the Church was not to make men think rationally, but to open their minds to every sort of antique nonsense
