Philosophical Background

Abstract

Abstract This chapter provides a brief overview of certain elements of Kant’s metaphysics and epistemology that are essential background for understanding certain features of his ethical theory. In particular, it presents Kant’s distinction between the ‘world of sense’ or ‘phenomenal world’ and the ‘world of understanding’ or ‘noumenal world’ as a basis for explaining the limits of theoretical cognition which rules out theoretical cognition and knowledge of God, immortality of the soul, and freedom of the will, yet allows Kant to affirm their reality on moral grounds, needed to explain how the highest good is possible. Of importance for understanding certain claims in his work on virtue is the distinction between the phenomenal world and the noumenal world as it applies to human beings. The chapter concludes with reflections on the relation between Kant’s ethics and his metaphysical and epistemological commitments.
