We all know how the size of sums of money appears to vary in a remarkable way according as they are being paid in or paid out.

The new understanding of the universe has come about through the new knowledge amassed in the last hundred years — by psychologists, biologists, and other scientists, by archaeologists, anthropologists, and historians. It has defined man's responsibility and destiny — to be an agent for the rest of the world in the job of realizing its inherent potentialities as fully as possible. It is as if man had been suddenly appointed managing director of the biggest business of all, the business of evolution — appointed without being asked if he wanted it, and without proper warning and preparation. What is more, he can't refuse the job. Whether he wants to or not, whether he is conscious of what he is doing or not, he is in point of fact determining the future direction of evolution on this earth. That is his inescapable destiny, and the sooner he realizes it and starts believing in it, the better for all concerned.

But if God and immortality be repudiated, what is left? That is the question usually thrown at the atheist's head. The orthodox believer likes to think that nothing is left. That, however, is because he has only been accustomed to think in terms of his orthodoxy. In point of fact, a great deal is left.

That is immediately obvious from the fact that many men and women have led active, or self-sacrificing, or noble, or devoted lives without any belief in God or immortality. Buddhism in its uncorrupted form has no such belief; nor did the great nineteenth-century agnostics; nor do the orthodox Russian Communists; nor did the Stoics. Of course, the unbelievers have often been guilty of selfish or wicked actions; but so have the believers. And in any case that is not the fundamental point. The point: is that without these beliefs men and women may yet possess the mainspring of full and purposive living, and just as strong a sense that existence can be worth while as is possible to the most devout believers.
