Modalization and demodalization: On the phenomenology of negation

Negation is widely thought to be uniquely captured by the usual extensional Boolean connective in the setting of classical logic. However, there has been recent interest in a modal approach to negation. This essay examines the problem of modal negation with an Husserlian phenomenological lens. I argue that the Husserlian approach to negation contains an ambiguity which points to a pluralism about negation. On this view, negation begins its life as a modal notion with nonclassical properties, and the question of classical negation is a question of its demodalization. I reconstruct a phenomenological legitimation of the demodalization, but I remain skeptical about its wider prospects. Nevertheless, the phenomenological‐modal approach to negation answers the skepticism about the very possibility of debates about negation and gives valuable insight into the fundamental nature of the problem. The argument should be of interest both to those who are specifically interested in Husserl's logic and the relationship of phenomenology to intuitionistic (and other nonclassical) logics, as well as to philosophers of logic more generally interested in obtaining different angles on the problem of negation from a systematic perspective.
