The eyeless fish
Form is always bound to its time…since it is nothing more than the means necessary today in which today’s revelation manifests itself…The form is the outer expression of the inner content.
Therefore one should not make a deity of form. And one should fight for the form only insofar as it can serve as a means of expression of the inner resonance. Therefore one should not seek salvation in one form…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.
—Wassily Kandinsky, “On the Problem of Form”
