O pensamento do pintor Gerhard Richter que em baixo se transcreve foi escrito em 1962 e publicado em 1995:
…Painting has nothing to do with thinking, because in painting thinking is painting. Thinking is language — record-keeping — and has to take
place before and after. Einstein did not think when he was calculating: he calculated — producing the next equation in reaction to the one went before — just as in painting one form is a response to another, and so on….
Gerhard Richter, The Daily Pratice of Painting, London, Thames and Hudson, 1995, p.13.
