Abstract
In the Preface to his best known work on moral philosophy, Kant states his purpose very clearly and succinctly: “The present groundwork is, however, nothing more than the search for and establishment of the supreme principle of morality, which already constitutes an enterprise whole in its aim and to be separated from every other moral investigation” (Groundwork 4:392). This paper will deal with the outcome of the first part of this task, namely, Kant’s attempt to formulate the supreme principle of morality, which is the intended outcome of the search. It will consider this formulation in light of Kant’s conception of the historical antecedents of his attempt.
