People carry around with them internalization's fixed-feature space learned early in life. Man is like other members of the animal kingdom , first, last and always a prisoner of his biological organism. No matter how hard he tries, it is impossible for him to the best himself of his own culture, where it has penetrated to the roots of his nervous system and determines how he perceives the world.

One of the most effective ways to learn about oneself is by taking seriously the cultures of others. It forces you to pay attention to those details of life which differentiate them from you.

Everything man is and does is modified by learning and is therefore malleable. But once learned, these behavior patterns, these habitual responses, these ways of interacting gradually sink below the surface of the mind and, like the admiral of a submerged submarine fleet, control from the depths. The hidden controls are usually experienced as though they were innate simply because they are not only ubiquitous but habitual as well.

Most of culture lies hidden and is outsidevoluntary control, making up the warp and weft of human existence. Even when small fragments of culture are elevated to awareness, they are difficult to change, not only because they are so personally experienced but because people cannotact or interact at all in any meaningful way except through the medium of culture.

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.

Culture is not made up but something that evolves which is human.

We are only peripherally tied to the lives of others. It takes a long long time for us to become deeply involved with others, and for some this never happens.
