For a while now I've been working in three areas, connected by my interest in investigating the nature of mathematics and its role in science.
In addition to writing on general topics in philosophy of science (especially explanation and understanding), I have studied certain issues in philosophy of physics. In particular, I am intrigued by several conceptual difficulties arising within the (so-called) 'non-fundamental' physics, more precisely in the less-studied domain of the condensed matter theory (including phenomena such as phase transitions, superconductivity, as well as the notions of symmetry and symmetry-breaking, etc.) I try to understand the 'more-is-different' idea (and its variations), so I investigate topics such as reduction, idealization, emergence, fundamentality, complexity, etc. A common theme here is the role of the mathematical formalism in expressing, or even shaping, the actual physical content of these theories. The philosophical relevance of these issues consists in clarifying physicists' accounts of familiar phenomena such as water boiling (and freezing) or of less mundane ones, such as the fact that (some) elementary particles have mass.
In the philosophy of mathematics, I continue to work mainly on issues related to the applicability of mathematics. This includes indispensability arguments, the 'unreasonable effectiveness' issue, also topics having to do with the role of mathematics in formulating explanations of physical phenomena, the various metaphysics of mathematics (realism/platonism, nominalism, fictionalism, etc.) A new angle on the connection between mathematics and the world is an attempt to evaluate how the experimental evidence gathered by cognitive psychologists and neuroscientists is relevant for the philosophical debates on the nature of mathematical (and logical) knowledge. I recently edited a volume collecting work in this area by philosophers, psychologists and cognitive scientists. In terms of philosophical significance, it all boils down to two deceivingly simple questions: what is to say that 1+1=2 is true, and how we can know that.
My interests in the history of analytical philosophy focus on the views of Quine and later Wittgenstein - both of whom I regard as 'naturalist' (despite obvious differences). My focus is on their take on modality, especially in relation to mathematics and logic. The basic question here is what these two thinkers (and those following in their footsteps) make of the claim that certain facts can't be otherwise than they are.
