The present paper elucidates, elaborates, and defends the main thesis advanced in the target article: namely, that natural-language sentences play a constitutive role in some human thought processes, and that they are responsible for some of the distinctive flexibility of human thinking, serving to integrate the outputs of a variety of conceptual modules. Section R1 clarifies and elaborates this main thesis, responding to a number of objections and misunderstandings. R2 considers three contrasting accounts of the mechanism of inter-modular integration. R3 discusses objections to some of the empirical data supporting my main thesis. R4 criticizes some competing theories of the role of language in cognition. And R5 considers some proposed supplementary cognitive roles which language might play.

In this chapter I defend the mind-blindness theory of autism, by showing how it can accommodate data which might otherwise appear problematic for it. Specifically, I show how it can explain the fact that autistic children rarely engage in spontaneous pretend-play, and also how it can explain the executive-function deficits which are characteristic of the syndrome. I do this by emphasising what I take to be an entailment of the mind-blindness theory, that autistic subjects have difficulties of access to their own mental states, as well as to the mental states of other people

What is the relationship between common-sense, or 'folk', psychology and contemporary scientific psychology? Are they in conflict with one another? Or do they perform quite different, though perhaps complementary, roles? George Botterill and Peter Carruthers discuss these questions, defending a robust form of realism about the commitments of folk psychology and about the prospects for integrating those commitments into natural science. Their focus throughout the book is on the ways in which cognitive science presents a challenge to our common-sense self-image - arguing that our native conception of the mind will be enriched, but not overturned, by science. The Philosophy of Psychology is designed as a textbook for upper-level undergraduate and beginning graduate students in philosophy and cognitive science, but as a text that not only surveys but advances the debates on the topics discussed, it will also be of interest to researchers working in these areas.
