In his poem, “Reason,” C. S. Lewis calls attention to dimensions of reality that are not easily probed by the rational mind alone. Reason, personified as Athena, must be complemented by imagination, personified as Demeter. Thus Lewis draws a critical distinction between knowing something imaginatively and knowing by means of critical-rational method. Both are necessary. In this paper Jerry Camery-Hoggatt argues that complementarity is rooted in three realities: the physical world, the knowing mind, and language as a mediator between these two.
