Pylyshyn raises hot topics like the number and kinds of pictorialist theories there are and their explanatory power. Pylyshyn states that pictorialists have only two possibilities – they can posit either “only functional” images or “really spatial” images – and that neither of these possibilities is convincing or sufficient in explanatory power for empirical and theoretical reasons. Is pictorialism, in principle, untenable?

Conversational contextualism states that the truth-conditions expressed by knowledge-attributing sentences vary relative to the context of utterance. This context is determined partly by different standards the person involved must meet in order to make the sentence true. I am concerned with the question of how these standards can be raised or lowered, and especially what happens to the standards and the conversational score when parties in a discussion push the conversational scores in different directions. None of the available options for (...) an answer seems satisfying. I argue that this results from a misunderstanding of the characteristics of the situation at hand. (shrink)

According to Bickle, certain empirical results demonstrate that the bottom-up reduction of phychological concepts to the concepts of neuroscience has already been accomplished. I argue that this conclusion is hasty. Bickle claims that all high-level investigations depend on a mistake. I argue that this overstates the explanatory character of neuroscientific findings. Bickle's assessment is highly optimistic, but he is far from making a decisive argument. Those who wait for a full-blown reductionism will have to wait a little longer.
