What is the nature of thought? Is thought linguistic and some kind of silent speech? Or is it pre-linguistic and some kind of association of ideas and images in the mind? Does it happen in the brain? I will focus on the last question, but also say something about the other two. I will present a simple thought experiment to show that thought must somehow happen in the brain. But then I will soften the impression this might give by pointing out what is needed to read those thoughts. Simply put, ontologically thought is in the brain, epistemologically it is not.

The main ideas in this paper can be summarized in the following three points. (1) Openness, indeterminacy, and exemplarity are elements of both Kant's aesthetics and Wittgenstein's notion of language games. (2) These elements are essential to what makes a person. They are necessary in processes of decision-making and in the development of a person. (3) Such aspects were in the center of discussion during the eighteenth and nineteenth centuries in Europe, especially in the tradition of the so-called Bildungsroman. Unfortunately, they tend to be forgotten nowadays.

In the preface to On Certainty Anscombe and von Wright say that in 1949 Malcolm suggested to Wittgenstein to think again about Moore’s “Defense of Common Sense” (1925) and “Proof of an External World” (1939). Malcolm himself had written on the issue in “Defending Common Sense” (1949). In the preface to the Philosophical Investigations Wittgenstein quotes Nestroy saying that there is usually very little progress in philosophy. But I think some progress has been made from Moore and Malcolm to Wittgenstein regarding skepticism. There is more awareness of practice and perspective and this opens the discussion in novel ways. But it also gives rise to new problems, in particular of morality and relativity.
