Inside I am the other of a self,
who feels a presence always close at hand,
one side or the other, knows another one
unlocks the door and quickly enters in.
Either as or, we live a common person.
Two is still one. It cannot live apart.
(Francesco Clemente, 'Poem for Paradigm', reproduced in Francesco Clemente, exh. cat., New York, 1999, p. 203)
