I shall treat the nature and power of the Affects, and the power of the Mind over them, by the same Method by which, in the preceding parts, I treated God and the Mind, and I shall consider human actions and appetites just as if it were a Question of lines, planes, and bodies.

The study of man is the study of his extensions.

It is characteristic of all extension systems to be treated as distinct and separate from the user and to take on an identity of their own. Religions, philosophies, literature, and art illustrate this. After a time, the extended system accretes to itself a past and a history as well as a body of knowledge and skills that can be learned. Such systems can be studied and appreciated as entities in themselves.

From now on, how one arrives at a definition of the relationship of man's basic nature to his culturally conditioned control systems (extensions) is of crucial importance. For in our shrinking globe man can ill afford cultural illiteracy.

To carry the atmosphere of God’s Glory is to extend it to the whole earth
