Context: The spectator experiences the phenomenon of transmutation; through the change from inert matter into a work of art, an actual transubstantiation has taken place... All in all, the creative act is not performed by the artist alone; the spectator brings the work into contact with the external world by deciphering and interpreting its inner qualifications and thus adds his contribution to the creative act.

Context: In the chessboard of life, the different pieces have powers which vary with the context and the possibilities of their combination are numerous and unpredictable. The sound player has a sense of right and feels that, if he does not follow it, he will be false to himself. In any critical situation the forward move is a creative act.

A Soldier's Declaration (July 1917)
Context: I am making this statement as an act of wilful defiance of military authority, because I believe that the War is being deliberately prolonged by those who have the power to end it.
I am a soldier, convinced that I am acting on behalf of soldiers. I believe that this War, on which I entered as a war of defence and liberation, has now become a war of aggression and conquest.

Context: Perhaps the meaning of all human activity lies in the artistic consciousness, in the pointless and selfless creative act? Perhaps our capacity to create is evidence that we ourselves were created in the image and likeness of God?
