In plain, what passes for a curriculum in today's schools is little else than a strategy of distraction... It is largely defined to keep students from knowing themselves and their environment in any realistic sense; which is to say, it does not allow inquiry into most of the critical problems that comprise the content of the world outside the school (...one of the main differences between the "advantaged" student and the "disadvantaged" is that the former has an economic stake in giving his attention to the curriculum while the latter does not. In other words, the only relevance of the curriculum for the "advantaged" student is that, if he does what he is told, there will be a tangible payoff.)

We must keep in mind the story of the statistician who drowned while trying to wade across a river with an average depth of four feet.

The BASIC FUNCTION of all education, even in the most traditional sense, is to increase the survival prospects of the group. If this function is fulfilled, the group survives. If not, it doesn't. There have been times when this function was not fulfilled, and groups (some of them we even call "civilizations") disappeared. Generally, this resulted from changes in the kind of threats the group faced. The threats changed, but the education did not, and so the group, in a way, "disappeared itself" (to use a phrase from Catch-22). The tendency seems to be for most "educational" systems, from patterns of training in "primitive" tribal societies to school systems in technological societies, to fall imperceptibly into a role devoted exclusively to the conservation of old ideas, concepts, attitudes, skills, and perceptions. This happens largely because of the unconsciously held belief that these old ways of thinking and doing are necessary to the survival of the group. …Survival in a stable environment depends almost entirely on remembering the strategies for survival that have been developed in the past, and so the conservation and transmission of these becomes the primary mission of education. But, a paradoxical situation develops when change becomes the primary characteristic of the environment. Then the task turns inside out — survival in a rapidly changing environment depends almost entirely upon being able to identify which of the old concepts are relevant to the demands imposed by the new threats to survival, and which are not. Then a new educational task becomes critical: getting the group to unlearn (to "forget") the irrelevant concepts as a prior condition of learning. What we are saying is that the "selective forgetting" is necessary for survival.
