David Birnbaum’s God and Evil is a major philosophical study which systematically confronts the philosophical problem of evil, and the Holocaust in particular.  It presents an extensively researched and comprehensive review of the subject.  In a clearly presented and readable exposition, Birnbaum then proposes an original and powerful formulation. Combining modern and classic, rationalist and mystic themes, Birnbaum’s proposed solution to the ancient problem of evil is perhaps the most elegant to appear in modern times.

David Birnbaum's  Summa Metaphysica  philosophy treatise  proposes  a universal common denominator - Q4P - aka Quest for Potential.
