The book "Philosophical Foundations of Neuroscience" is an engaging criticism of cognitive neuroscience from the perspective of a Wittgensteinian philosophy of ordinary language. The authors' main claim is that assertions like "the brain sees" and "the left hemisphere thinks" are integral to cognitive neuroscience but that they are meaningless because they commit the mereological fallacy—ascribing to parts of humans, properties that make sense to predicate only of whole humans. The authors claim that this fallacy is at the heart of Cartesian (...) dualism, implying that current cognitive neuroscientists are Cartesian dualists. Against this claim, we argue that the fallacy cannot be committed within Cartesian dualism either, for this doctrine does not allow for an intelligible way of asserting that a soul is part of a human being. Also, the authors' Aristotelian essentialistic outlook is at odds with their Wittgensteinian stance, and we were unconvinced by their case against explanatory reductionism. Finally, although their Wittgensteinian stance is congenial with radical behaviorism, their separation between philosophy and science seems less so because it is based on a view of philosophy as a priori. The authors' emphasis on the a priori, however, does not necessarily commit them to rationalism if it is restricted to conceptual or analytical truths. (shrink)

Writing from a scientifically and philosophically informed perspective, the authors provide a critical overview of the conceptual difficulties encountered in many current neuroscientific and psychological theories.

Wittgenstein wrote ‘While thinking philosophically we see problems in places where there are none. It is for philosophy to show that there are no problems’. He meant that the ‘problems’ philosophers grapple with are of their own making. In a related remark he said: ‘This is the essence of a philosophical problem. The question itself is the result of a muddle. And when the question is removed, this is not by answering it’. Even more explicitly he said: ‘All that philosophy (...) can do is to destroy idols’. As he understood his job, it was not to produce or construct something; his job was entirely destructive. This is how Wittgenstein thought of philosophy when he thought about it in the abstract, and I share this view of philosophy. I believe that when we see how to dispose of all philosophical categories, our job is finished. For example, in epistemology our job is not to argue that it is possible to know such-and-such because so-and-so; rather, we undermine all those ideas that make it seem as though we could not know such-and-such. Undermining philosophical ideas takes the form: When we philosophise, we are tempted to think so-and-so, but if we consider that idea, and do so while remaining free of all philosophical jargon, we find that we cannot make sense of it.
