"Galileo on the Distinction between Primary and Secondary Qualities (I). A Superessentialist Argument" Galileo’s distinction between primary and secondary qualities has hitherto been examined almost exclusively from a contextual, historical perspective. This paper, the first of two planned, aims to fill this gap by providing a systematic, theoretical analysis of his principal argument for the distinction, as advanced in "The Assayer". I begin with a reconstruction of the key steps in the argument, and then proceed to identify and discuss the (...) epistemological and ontological presuppositions underpinning it. I argue that the most crucial and original assumption behind Galileo’s reasoning is the superessentialist principle, implying the mutual conditionality of the essentiality and reality of a material body’s properties. An in-depth analysis of the assumptions underlying Galileo’s reasoning paves the way for further examination of the most controversial aspect of his theory, that is, the ontological status of the secondary qualities. This issue will be addressed in the second forthcoming paper. (shrink)

Abstract: The notion that philosophy can be practised as a kind of therapy has become a focus of debate. This article explores how philosophy can be practised literally as a kind of therapy, in two very different ways: as philosophical therapy that addresses “real-life problems” (e.g., Sextus Empiricus) and as therapeutic philosophy that meets a need for therapy which arises in and from philosophical reflection (e.g., Wittgenstein). With the help of concepts adapted from cognitive and clinical psychology, and from cognitive (...) linguistics, the article shows that both philosophical projects address important and literally therapeutic tasks and explains how they can do so with genuinely philosophical argument and analysis. This brings into view new applications for philosophy, a need for therapy in core areas of the subject, and the outline of a new approach to meet what will be shown to be a central need. (shrink)

The paper develops and addresses a major challenge for therapeutic conceptions of philosophy of the sort increasingly attributed to Wittgenstein. To be substantive and relevant, such conceptions have to identify “diseases of the understanding” from which philosophers suffer, and to explain why these “diseases” need to be cured in order to resolve or overcome important philosophical problems. The paper addresses this challenge in three steps: With the help of findings and concepts from cognitive linguistics and cognitive psychology, it redevelops the (...) Wittgensteinian notion of “philosophical pictures.” Through a case study on seminal versions of familiar mind-body problems, it examines how such pictures shape philosophical reflection and generate ill-motivated but captivating problems. Third, it shows that philosophical pictures are constitutive of “diseases of the understanding,” in a quite strict sense of the term. On this basis, the paper explains when and why philosophical therapy is required. (shrink)
