Abstract

This paper represents an attempt to indicate the idea of a logic slightly more general than sentential calculus, which is applicable to many philosophical issues. In particular, I shall use this generalized calculus to discuss a variation of the logic of imperatives. In part I, certain general considerations about indicative calculi provide the basis, as well as indicate the need, for the more formal construction of part II. Part III illustrates the analytical power of the tool constructed, and tries to show its relevance for philosophy.
