Requisites: the logic of intensions

Abstract

In Section 2.4.1 we argued in favour of semantic anti-actualism: the actual of all the possible worlds should play no semantic role. In this and the following sections we outline an essentialism that likewise accords no privileged status to the actual world by making the notion of essence independent of world and time and a priori instead . 1 At the same time we are arguing in favour of ontological actualism: all the individuals at the actual world are all the individuals there are at all the other possible worlds as well (hence, there are no merely possible individuals, or possibilia ).
