Humanism involves far more than the negation of supernaturalism. It requires an affirmative philosophy . . . translated into a life devoted to one's own improvement and the service of all mankind.

I think . . . that philosophy has the duty of pointing out the falsity of outworn religious ideas, however estimable they may be as a form of art. We cannot act as if all religion were poetry while the greater part of it still functions in its ancient guise of illicit science and backward morals. . . .

To define twentieth-century humanism briefly, I would say that it is a philosophy of joyous service for the greater good of all humanity in this natural world and advocating the methods of reason, science, and democracy.

Supernatural entities simply do not exist. This nonreality of the supernatural means, on the human level, that men do not possess supernatural and immortal souls; and, on the level of the universe as a whole, that our cosmos does not possess a supernatural and eternal God.

There is no place in the Humanist worldview for either immortality or God in the valid meanings of those terms. Humanism contends that instead of the gods creating the cosmos, the cosmos, in the individualized form of human beings giving rein to their imagination, created the gods.

Humanism believes that the individual attains the good life by harmoniously combining personal satisfactions and continuous self-development with significant work and other activities that contribute to the welfare of the community.

The cause-effect sequences in our brains are just as determining, just as inescapable, as anywhere else in Nature.
