"It might be thought that the I Ching and the oracles are metaphysical while the computer model is "real"; but the fact remains that a machine to foretell the future is based on metaphysical assumptions of a very definite kind. It is based on the implicit assumption that "the future is already here," that it exists already in a determinate form, that it requires merely good instruments and good techniques to get it into focus and make it visible. The reader will agree that this is a very far-reaching metaphysical assumption which seems to go against all direct personal experience."
