He Is There and He Is Not Silent is a philosophical work written by American apologist and Christian theologian Francis A. Schaeffer, Wheaton, IL:Tyndale House, first published in 1972.
First, what Schaeffer calls the "Line of Despair" (and associates with existentialism): that there is no logical answer to the dilemmas, and that all is "chaotic, irrational, and absurd."
Schaeffer characterizes this view as impossible to hold in practice, because order is necessary for life.
The second class of answers Schaeffer postulates is that logic exists, and that the subject of metaphysics is open to rational discussion.
Schaeffer also attacks pantheism in this vein, which he labels "paneverythingism," propounding that while it provides an answer for unity and universals, it fails to explain the origin of diversity and particulars.
In addition to providing an explanation for both complexity and personality, Schaeffer writes that the answer to the dilemma of both unity/universals and diversity/particulars may be found in the doctrine of the Trinity.
Returning to the two dilemmas given at the beginning of the chapter, Schaeffer describes what he calls the "Personal-Infinite God."
