We speak of concrete and not abstract painting because nothing is more concrete, more real than a line, a color, a surface.

There is an old and a new consciousness of the age. The old one is directed towards the individual. The new one is directed towards the universal. The struggle of the individual against the universal may be seen both in the world war and in modern art.

...every machine is the spiritualization of an organism.

Each superfluous line, each wrongly placed line, any color placed without veneration or care, can spoil everything, that is, the spiritual.

The square is to us what the cross was to the early Christians.

he line has almost become a work of art in itself; one can not play with it when the representation of objects perceived was all-important.

In place of the dream, the future will put art on a scientific and technical basis.
