More quotes by Bertrand Russell

Image
Human nature is so constructed that it gives affection most readily to those who seem least to demand it.
Bertrand Russell
Image
In attempting to understand the elements out of which mental phenomena are compounded, it is of the greatest importance to remember that from the protozoa to man there is nowhere a very wide gap either in structure or in behaviour. From this fact it is a highly probable inference that there is also nowhere a very wide mental gap.
Bertrand Russell
Image
In adolescence, I hated life and was continually on the verge of suicide, from which, however, I was restrained by the desire to know more mathematics. Now, on the contrary, I enjoy life I might almost say that with every year that passes I enjoy it more.
Bertrand Russell
Image
In human relations one should penetrate to the core of loneliness in each person and speak to that.
Bertrand Russell
Image
No rules, however wise, are a substitute for affection and tact.
Bertrand Russell
Image
[One] must look into hell before one has any right to speak of heaven.
Bertrand Russell
Image
If one lived for ever the joys of life would inevitably in the end lose their savour. As it is, they remain perennially fresh.
Bertrand Russell
Image
Some `advanced thinkers' are of the opinion that anyone who differs from the conventional opinion must be in the right. This is a delusion if it were not, truth would be easier to come by than it is.
Bertrand Russell
Image
For my part, the thing I would wish to obtain from money would be leisure with security. But what the typical modern man desires to get with it is more money, with a view to ostentation, splendour, and the outshining of those who have hitherto been his equals.
Bertrand Russell
Image
Many orthodox people speak as though it were the business of sceptics to disprove received dogmas rather than of dogmatists to prove them. This is, of course, a mistake.
Bertrand Russell
Image
Although this may seem a paradox, all exact science is based on the idea of approximation. If a man tells you he knows a thing exactly, then you can be safe in inferring that you are speaking to an inexact man.
Bertrand Russell
Image
The supreme maxim in scientific philosophising is this: wherever possible, logical constructions are to be substituted for inferred entities.
Bertrand Russell
Image
Philosophers, for the most part, are constitutionally timid, and dislike the unexpected. Few of them would be genuinely happy as pirates or burglars. Accordingly they invent systems which make the future calculable, at least in its main outlines.
Bertrand Russell
Image
Religion is based ... mainly upon fear ... fear of the mysterious, fear of defeat, fear of death. Fear is the parent of cruelty, and therefore it is no wonder if cruelty and religion have gone hand in hand. My own view on religion is that of Lucretius. I regard it as a disease born of fear and as a source of untold misery to the human race.
Bertrand Russell
Image
We are all prone to the malady of the introvert who with the manifold spectacle of the world spread out before him, turns away and gazes only upon the emptiness within.
Bertrand Russell
Image
Is a man what he seems to the astronomer, a tiny lump of impure carbon and water crawling impotently on a small and unimportant planet? Or is he what he appears to Hamlet? Is he perhaps both as once?
Bertrand Russell
Image
Many a man will have the courage to die gallantly, but will not have the courage to say, or even to think, that the cause for which he is asked to die is an unworthy one.
Bertrand Russell
Image
None but a coward dares to boast that he has never known fear.
Bertrand Russell
Image
In emancipation from the fears that beset the slave of circumstance he will experience a profound joy, and through all the vicissitudes of his outward life he will remain in the depths of his being a happy man.
Bertrand Russell
Image
Boredom is... a vital problem for the moralist, since half the sins of mankind are caused by the fear of it.
Bertrand Russell
