An experimental analysis shifts the determination of behaviour from autonomous man to the environment - an environment responsible both for the evolution of the species and for the repertoire acquired by each member. Early versions of environmentalism were inadequate because they could not explain how the environment worked, and much seemed to be left for autonomous man to do. But environmental contingencies now take over functions once attributed to autonomous man, and certain questions arise. Is man then 'abolished'? Certainly not as a species or as an individual achiever. It is the autonomous inner man who is abolished, and that is a step forward. But does man not then become merely a victim or passive observer of what is happening to him? He is indeed controlled by his environment, but we must remember that it is an environment largely of his own making. The evolution of a culture is a gigantic exercise in self-control. It is often said that a scientific view of man leads to wounded vanity, a sense of hopelessness, and nostalgia. But no theory changes what it is a theory about; man remains what he has always been. And a new theory may change what can be done with its subject matter. A scientific view of man offers exciting possibilities. We have not yet seen what man can make of man.
