Theo van Doesburg was a jack of all trades: painter, writer, architect, typographer, and art theorist. In this volume of the Bauhausbucher, he attempts to make elementary concepts in the visual arts generally comprehensible. He was addressing the "modern artist" of his day, who had to deal with both shifting social paradigms and a changing understanding of art and art theory. Van Doesburg describes theory as a necessary consequence of creative practice. Artists, he says, "do not write about art but from within art." 32 illustrations
