The free, initiating, creative play of purpose needs fixed laws, constraints, and a deterministic framework through which to realize its goal. Young's process paradigm deals expressly with this interplay of freedom and constraint. Two of these aspects are objective while two are nonobjective or projective. Young devotes much of his second book, The Geometry of Meaning, to an exposition of the fourfold. The importance of the discovery of fourfold reality to the construction of a New Age paradigm cannot be overemphasized.
Science assumes that reality is monistic, i.e., that there is only one kind of ultimate substance.
Mind, for example, is generally viewed as an epiphenomenon of the brain, not as part of a basic dualism in nature. Young alone, however, has seen the power and necessity of a fourfold analytical interpretation of objective and projective reality. In order to function, universal process requires not one but two dualisms, two pairs of opposites that mediate each other. The concept of fourfold reality is the formal entry into the theory of process. Unless one grasps it the full power of Young's insights and the formal integrity and validity of the theory will be missed.
