An individual is generally ready to admit that he is ignorant of periods in the past or places on the other side of the globe. But he is much less likely to admit ignorance of his own period and his own place, especially if he is an intellectual. Everyone, of course, knows about his own society. Most of what he knows, however, is what Alfred Schultz has aptly called “recipe knowledge”—just enough to get him through his essential transactions in social life. Intellectuals have a particular variety of “recipe knowledge”; they know just enough to be able to get through their dealings with other intellectuals. There is a “recipe knowledge” for dealing with modernity in intellectual circles; the individual must be able to reproduce a small number of stock phrases and interpretive schemes, to apply them in “analysis” or “criticism” of new things that come up in discussion, and thereby to authenticate his participation in what has been collectively been defined as reality in these circles. Statistically speaking, the scientific validity of this intellectuals’ “recipe knowledge” is roughly random.

Perhaps some little boys consumed with curiosity to watch their maiden aunts in the bathroom later become inveterate sociologists. This is quite uninteresting. What interests us is the curiosity that grips any sociologist in front of a closed door behind which there are human voices.

Man is biologically predestined to construct and to inhabit a world with others. This world becomes for him the dominant and definite reality. Its limits are set by nature, but, once constructed, this world acts back upon nature. In the dialectic between nature and the socially constructed world the human organism itself is transformed. In this same dialectic man produces reality and thereby produces himself.
