'It was the block of the body itself, that is to say the trunk and part of the thighs, that fascinated me. The hands, the arms, the head, the legs were of no importance. Only the body is alive, all-powerful, and non-thinking. The head, the arms, the hands are only intellectual articulations around the bulk of flesh that is the body! The heart beats without thought on our part; the mind cannot stop it.’ (Y. Klein quoted in S. Stich, Yves Klein, Ostfildern 1994, p. 175).
