Kandinsky, Wassily – painter, printmaker and author – the first painter to base painting on purely pictorial means of expression and abandon objects … - Wassily Kandinsky

An artist who sees that the imitation of natural appearances, however artistic, is not for him – the kind of creative artist who wants to, and has to express his own inner world – sees with envy how naturally and easily such goals can be attained in music, the least material of the arts today. Understandably, he may turn toward it and try to find the same means in his own art. Hence the current search for rhythm in painting, for mathematical abstract construction.. ..the way colors are set in motion, etc.

The geometric line is an invisible thing. It is the track made by the moving point; that is, its product. It is created by movement – specifically through the destruction of the intense self-contained repose of the point. Here, the leap out of the static to the dynamic occurs. […] The forces coming from without which transform the point into a line, can be very diverse. The variation in lines depends upon the number of these forces and upon their combinations.

Since the form is only an expression of the content and the content is different with different artists, it is then clear that there can be many different forms at the same time which are equally good. Necessity creates the form. Fish which live at great depths have no eyes. The elephant has a trunk. The chameleon changes its color, and so forth.
