Jacques Ellul, The Humiliation of the Word (Eerdmans, 1985), page 221:
We are arriving at a purely emotional stage of thinking. In order to begin reacting intellectually, we need the stimulus of an image. Bare information or an article or book no longer have any effect on us. We do not begin reflecting on such a basis, but only with an illustration. We need violent visual impact if thought is to be set in motion. When we jump from image to image, we are really going from emotion to emotion: our thought moves from anger to indignation, from fear to resentment, from passion to curiosity. In this manner our thought is enriched by diversity and multiple meaning but is singularly paralyzed with respect to its specific efficacy as thought.
