In his attempt to put forward an empiricist version of structuralism, van Fraassen develops an approach to scientific representation and models which has been the object of several critiques. Here we cover the “Loss of Reality Objection”, namely, that reality itself would play no role in science if science could only refer to mathematical models. We examine and dismiss the solution offered by van Fraassen. Finally, we offer an alternative solution path.

The article focuses on the unifying and explanatory power of the selective realism defended by Anjan Chakravartty. Our main aim is twofold. First, we critically analyse the purported synthesis between entity realism and structural realism offered by the author. We give reasons to think that this unification is an inconvenient marriage. In the second step, we deal with certain controversial aspects of the intended unification among three metaphysical concepts: causation, laws of nature and natural kinds. After pointing out that Chakravartty’s (...) conception of laws is a plausible view that a scientific realist might endorse, we contend, on the contrary, that the concept of natural kind is dispensable in the framework of Chakravartty’s realism.

In several works that start from the seminal text Language, Thought, and Other Biological Categories, Ruth Millikan has presented her well know teleosemantic approach to philosophy of mind and philosophy of language. Millikan presents her theory of linguistic signs as a theory which, unlike other semantic theories, is able to more adequately solve problems such as that which is called “Freges’s puzzle”. Millikan considers that the Fregean modes of presentation are inconsistent with a representational theory of mind. In this paper, (...) the relevance of Millikan’s objections to Frege is evaluated and the scope of these objections is discussed in the context of her own conception. We conclude that Millikan’s analysis of Fregean semantics relies on false assumptions and, in consequence, her doctrine is weakened. (shrink)
