M. C. Escher, was a Dutch graphic artist. He is known for his often mathematically inspired woodcuts, lithographs, and mezzotints. These feature impossible constructions, explorations of infinity, architecture, and tessellations.
The primary purpose of all art forms, whether it’s music, literature, or the visual arts, is to say something to the outside world; in other words, to make a personal thought, a striking idea, an inner emotion perceptible to other people’s senses in such a way that there is no uncertainty about the maker's intentions. 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 is no one who actually has only feeling or only thinking properties. They intermingle like the colors 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 or feeling, but believes that one cannot do without either the one or the other. At any rate, it is unprejudiced enough to wish for a better understanding between the two parties... It is clear that feeling and understanding are not necessarily opposites but that they complement each other. Only those who attempt the absurd will achieve the impossible. I think it's in my basement... let me go upstairs and check. I don't use drugs, my dreams are frightening enough. - Are you really sure that a floor can't also be a ceiling? M. C. Escher
