In scientific thought, the concept functions all the better for being cut off from all background images. In its full exercise, the scientific concept is free from all the delays of its genetic evolution, an evolution which is consequently explained by simple psychology. The virility of knowledge increases with each conquest of the constructive abstraction.
The image can only be studied through the image, by dreaming images as they gather in reverie. It is a non-sense to claim to study imagination objectively since one really receives the image only if he admires it. Already in comparing one image to another, one runs the risk of losing participation in its individuality.
Perhaps it is even a good idea to stir up a rivalry between conceptual and imaginative activity. In any case, one will encounter nothing but disappointments if he intends to make them cooperate. The image can not provide matter for a concept. By giving stability to the image, the concept would stifle its life.
In order to dream so far, is it enough to read? Isn't it necessary to write? Write as in our schoolboy past, in those days when, as Bonnoure says, the letters wrote themselves one by one, either in their gibbosity or else in their pretentious elegance? In those days, spelling was a drama, our drama of culture at work in the interior of a word.
