" But, as Sir Herbert Read remarks in his Concise History of Modern Art, metaphysical anxiety is no longer only Germanic and northern; it now characterizes the whole of the modern world. Read quotes Klee, who wrote in his Diary at the beginning of 1915: “The more horrifying this world becomes (as it is in these days) the more art becomes abstract; while a world at peace produces realistic art.” To Franz Marc, abstraction offered a refuge from the evil and ugliness in this world. “Very early in life I felt that man was ugly. The animals seemed to be more lovely and pure, yet even among them I discovered so much that was revolting and hideous that my painting became more and more schematic and abstract. "
