- Theo van Doesburg
"For - to say a few words on technique - whereas the curved line was used predominantly for reasons of beauty, (Phidias, Michelangelo, Raphael, Rubens) it has been used more and more economically for reasons of truth (Millet, Monet , Paul CÃ©zanne) until it will end as the straight line for reasons of Love. This will enable the art of the future to create an international form; a form understandable to all and vital enough to the expression of a general feeling of love in a monumental way. Such is the future."
