The concept of conscience serves as the locus of this apologetic for his contemporary significance. Further, this book offers a positive theory for identifying and describing the primary sources of contemporary moral nihilism, namely, reductive naturalism (scientism) and epistological relativism (perspectivalism). The logic and root assumptions of these theoretical viewpoints are then engaged and qualified--if not refuted--through an extended, comparative discussion of the theories of Freud and Nietzsche with those of Jung.
