"The only condition of fighting for the right to create is faith in your own vocation, readiness to serve, and refusal to compromise. Artistic creation demands of the artist that he 'perish utterly', in the full, tragic sense of those words. And so, if art carries within it a hieroglyphic of absolute truth, this will always be an image of the world, made manifest in the work once and for all time. And if cold, positivistic, scientific cognition of the world is like the ascent of an unending staircase, its artistic counterpoint suggests an endless system of spheres, each one perfect and contained within itself. One may complement or contradict another, but in no circumstances can they cancel each other out; on the contrary, they enrich one another, and accumulate to form an all-embracing sphere that grows out into infinity. These poetic revelations, each one valid and

eternal, are evidence of man's capacity to recognise in whose image and likeness he is made, and to voice this recognition.
Moreover, the great function of art is communication, since mutual understanding is a force to unite people, and the spirit of communion is one of the most important aspects of artistic

creativity. Works of art, unlike those of science, have no practical goals in any material sense. Art is a meta-language, with the help of which people try to communicate with one another; to impart information about themselves and assimilate the experience of others. Again, this has to do not with practical advantage but with realising the idea of love, the meaning of which is in sacrifice: the very antithesis of pragmatism. I simply cannot believe that an artist can ever work only for the sake of 'self-expression'. Self-expression is meaningless unless it meets with a response. For the sake of creating a spiritual bond with others it can only be an agonising process, one that involves no practical gain: ultimately, it is an act of sacrifice. But surely it cannot be worth the effort merely for the sake of hearing one's own echo?"
