M. C. Escher

“… I do indeed believe that there is a certain contrast between, say, people in scientific professions and people working in the arts. Often there is even mutual suspicion and irritation, and in some cases one group greatly undervalues the other.
Fortunately there in no one who actually has only feeling or only thinking properties. They intermingle like the colours of the rainbow and cannot be sharply divided. Perhaps there is even a transitional group, like the green between the yellow and the blue of the rainbow. This transitional group does not have a particular preference for thinking of feeling, but believes that one cannot do without the one or the other. At any rate, it is unprejudiced enough to wish for a better understanding between the two parties. …”
