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.
Gaston BachelardThe 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.
Gaston BachelardThe best proof of the specificity of the book is that it is at once a reality of the virtual and a virtuality of the real.
