Science is at no moment quite right, but it is seldom quite wrong, and has, as a rule, a better chance of being right than the theories of the unscientific. It is, therefore, rational to accept it hypothetically.

To speak seriously: the standards of "goodness" which are generally recognized by public opinion are not those which are calculated to make the world a happier place. This is due to a variety of causes, of which the chief is tradition, and the next most powerful is the unjust power of dominant classes.

Most people believe in God because they have been taught from early infancy to do it, and that is the main reason. Then I think that the next most powerful reason is the wish for safety.

Science tells us what we can know but what we can know is little and if we forget how much we cannot know we become insensitive of many things of very great importance. Theology, on the other hand induces a dogmatic belief that we have knowledge where in fact we have ignorance and by doing so generates a kind of impertinent insolence towards the universe. Uncertainty in the presence of vivid hopes and fears is painful, but must be endured if we wish to live without the support of comforting fairy tales.

All religions are both harmful and untrue.

Man is the product of causes which had no prevision of the end they were achieving; his origin, his growth, his hopes and fears, his loves and beliefs, are but the outcome of accidental collocations of atoms; no fire, no heroism, no intensity of though and feeling, can preserve an individual life beyond the grave.

Among the Tibetans, one wife has many husbands, because men are too poor to support a whole wife.
