In part I. of this essay we attempt to articulate Husserl’s phenomenological descriptions for the genesis of the primitive logical connectives, negation and disjunction. In part II. we describe possible worlds models for the use of disjunction and negation in epistemic contexts and contexts relating to the analysis of meanings. Finally, in part III, we

It details the author's attempt to develop a framework that is compatible with the denial of actualist accounts of modality. It also alludes to some ways that the contrast between modal naturalism and modal rationalism connects with many of the issues that ...
