To be happy in this world… it is necessary to feel oneself not merely an isolated individual whose day will soon be over, but part of the stream of life flowing on from the first germ to the remote and unknown future.
Whatever my personal activities, I may be defeated by death, or by certain kinds of diseases; I may be overcome by my enemies; I may find that I have embarked upon an unwise course which cannot lead to success. In a thousand ways the failure of purely personal hopes may be unavoidable, but if personal aims have been part of larger hopes for humanity, there is not the same utter defeat when failure comes. The man who is working for some much-needed reform … may be forced to realise that what he has worked for will not come about in his lifetime. But he need not on that account sink into complete despair, provided that he is interested in the future of mankind apart from his own participation in it.Bertrand Russell
