Schurman, Belief in God, 43—“I am unable to assign to our belief in God a higher certainty than that possessed by the working hypotheses of science.... 57—The nearest approach made by science to our hypothesis of the existence of God lies in the assertion of the universality of law ... based on the conviction of the unity and systematic connection of all reality.... 64—This unity can be found only in self-conscious spirit.” The fault of this reasoning is that it gives us nothing necessary or absolute. Instances of working hypotheses are the nebular hypothesis in astronomy, the law of gravitation, the atomic theory in chemistry, the principle of evolution. No one of these is logically independent or prior. Each of them is provisional, and each may be superseded by new discovery. Not so with the idea of God. This idea is presupposed by all the others, as the condition of every mental process and the guarantee of its validity. IV. Contents of this Intuition. 1. In this fundamental knowledge _that_ God is, it is necessarily implied that to some extent men know intuitively _what_ God is, namely, (_a_) a Reason in which their mental processes are grounded; (_b_) a Power above them upon which they are dependent; (_c_) a Perfection which imposes law upon their moral natures; (_d_) a Personality which they may recognize in prayer and worship. In maintaining that we have a rational intuition of God, we by no means imply that a presentative intuition of God is impossible. Such a presentative intuition was perhaps characteristic of unfallen man; it does belong at times to the Christian; it will be the blessing of heaven (Mat. 5:8—“the pure in heart ... shall see God”; Rev. 22:4—“they shall see his face”). Men’s experiences of face-to-face apprehension of God, in danger and guilt, give some reason to believe that a presentative knowledge of God is the normal condition of humanity. But, as this presentative intuition of God is not in our present state universal, we here claim only that all men have a rational intuition of God. It is to be remembered, however, that the loss of love to God has greatly obscured even this rational intuition, so that the revelation of nature and the Scriptures is needed to awaken, confirm and enlarge it, and the special work of the Spirit of Christ to make it the knowledge of friendship and communion. Thus from knowing about God, we come to know God (John 17:3—“This is life eternal, that they should know thee”; 2 Tim. 1:12—“I know him whom I have believed”).
