The notion of the third in recent years is seen by noted psychoanalysts as the locus of healing. Jung explored the third beginning in 1916 in a way strikingly postmodern in its implications for clinical work and for understanding reality. This article1 proposes that we cannot see the third except in the shadow of the fourth, and attempts to describe what the fourth is. The fourth remains shadowy (suggesting two meanings of shadow); it is only known by living it, for we are part of the larger reality it discloses. In experiencing this fourth, we are led to develop whatever we each leave out. Hence the aliveness of the fourth engenders a new kind of consciousness of the bigger surround, the moreness of reality as a whole that includes and transcends the psyche.
