ABSTRACT
In the last three chapters I have been trying to show how the traditional distinguishing marks of man-speech, rationality, culture-are not something opposed to our nature, but continuous with and growing out of it. Our need for some form of them is natural, not an accidental, external need like the “need for a car,” which might as well or better be served by a horse or a helicopter. But this means that facts about our other needs, about our whole system of needs, have to come in to determine what sort of culture, what rational way of life, can suit us. Our full emotional nature determines our aims, as well as the formal, structural characteristics discussed so far.
