chapter  IV
A CLOSE LOOK AT THE DISPLACEMENT OF CONCEPTS
Pages 56

So far I have posed the problem of the emergence of new concepts, and suggested that new concepts come through the shift of old concepts to new situations. In this process the old concept is not applied to the new situation, as a concept to an instance, but is taken as a symbol or metaphor for the new situation. The new concept grows out of the making, elaboration and correction of the metaphor. There is no one point at which it emerges since the process is continuous, like the emergence of a biological species, and its freezing at any one point is always arbitrary.
