To illustrate the difference between the innovator and the dull crowd of routinists who cannot even imagine that any improvement is possible, we need only refer to a passage in Engel's most famous book.

The primary focus of a valuer is not to take the world as it comes and pass judgment. His primary focus is to identify what might and ought to exist, to uncover potentialities that he can exploit, to find ways of reshaping the world in the image of his values.
