The Maker's Intentions

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.

-- M. C. Escher (1898-1972), Dutch artist, On Being a Graphic Artist
