The article deals with the charge of irrelevance levelled against D. Lewis’s modal realism, notably known as a reductionist account of modality. The charge of irrelevance is apparently one of the most popular objections to modal realism though it often seems that the debate surrounding this charge is not very fruitful since in this context it is common to appeal, implicitly or explicitly, to different criteria for theory choice. As a result, the article deals with the problem in a slightly (...) different manner. The article addresses arguments aimed to show that, contrary to what is often stated, modal realism does not violate our pre-theoretical intuitions, as well as arguments aimed to respond to the charge of irrelevance without appealing to criteria for theory choice at all but providing different reasons instead. However, the aim of this article is to show that all these arguments are rather unconvincing. (shrink)

This book develops a novel theory of intentionality. It argues that intentionality is an internal essential relation of constitution between an intentional state and an object or between such a state and a possible state of affairs as subsisting. The author's main claim is that intentionality is a fundamentally modal property, hence a non (scientifically) natural property in that it does not supervene, either locally or globally, on its nonmodal physical basis. This is the property, primarily for an intentional mental (...) state, to be constituted by the entities it is about. In the case of intentionality of reference, such constituents are objects, in the sense of individuals; in the case of intentionality of content, such constituents are possible states of affairs as subsisting. Constitution is meant in a mereologically literal sense: those constituents are essential parts of the relevant states. As a result, the theory claims not only that intentionality is relational, but also that is an internal, essential relation holding between an intentional state and its object or proposition-like content. Intentionality as Constitution will be of interest to scholars and advanced students working in philosophy of mind, philosophy of language, metaphysics, and cognitive science. (shrink)
