“...if love...is a function of man's sadness, friendship is a function of his cowardice; and if neither can be realised because of the impenetrability (isolation) of all that is not 'cosa mentale,' at least the failure to possess may have the nobility of that which is tragic, whereas the attempt to communicate where no communication is possible is merely a simian vulgarity, or horribly comic, like the madness that holds a conversation with the furniture. - For an artist therefore, the only possible spiritual development is in the sense of depth. The artistic tendency is not expansive, but a contraction. And art is the apotheosis of solitude. There is no communication because there are no vehicles of communication.”
