No doubt one can easily imagine, by an illusion similar to that which makes everything on the horizon appear equidistant, that all the revolutions which have hitherto occurred in painting or in music did at least show respect for certain rules, whereas that which immediately confronts us, be it impressionism, a striving after discord, an exclusive use of the Chinese scale, cubism, futurism or what you will, differs outrageously from all that have occurred before. Simply because those that have occurred before we are apt to regard as a whole, forgetting that a long process of assimilation has melted them into a continuous substance, varied of course but, taking it as a whole, homogeneous, in which Hugo blends with Molière. Let us try to imagine the shocking incoherence that we should find, if we did not take into account the future, and the changes that it must bring about, in a horoscope of our own riper years, drawn and presented to us in our youth.
