Abstract

The aim of this paper is to show that descriptive statements can be action-Guiding; that oughts and imperatives, If they are to be justified at all, Must be derived from statements of fact; that factual-Prudential moral reasoning is logically universalizable; and that the demand for universalizability, And thus ultimately for moral reasoning, Is itself only prudentially justifiable. These points are argued by way of an examination and criticism of hare's discussion of prescription and universalizability in moral reasoning
