This article was inspired by participant observation of a contemporary collaboration between empirically oriented philosophers of mind and neuroscientists. An encounter between this anthropologist of science and neurophilosophers in a Finnish sleep laboratory led to the following philosophical exploration of the intellectual space shared by neurophilosophy and science studies. Since these fields emerged in the 1970s, scholars from both sides have been visiting brain research facilities, but engaged with neuroscientists very differently and passionately fought with each other over the reduction (...) of mind to brain. As a case in point, this article looks at the philosophical controversy over the dreaming brain. It serves as a window on the problem space opened up by the demise of positivist conceptions of science, now inhabited by both neurophilosophy and science studies. Both fields face the problem of how to bridge the gap between empirical research and conceptual work. At a time when ontological speculation has made a comeback in these areas of research, studies on how epistemic objects manifest themselves in the material culture of neuroscience could help neurophilosophers to become better materialists. In the sleep laboratory, however, the materiality of dreams continues to be elusive. In dreaming science studies and neurophilosophy encounter a phenomenon that – at least in 2015 – still invites a positivist rather than a materialist attitude. (shrink)

Norman Malcolm wrote:That something is implausible or Impossible does not go to show that I did not dream it. In a dream I can do the impossible in every sense of the word.Malcolm nowhere suggests why this remark should be regarded as true. Indeed, many philosophers would regard it is palpably false. After all, it is not at all obvious that one can hope for, intend to do, or believe what is in every sense of the word, impossible. I think, (...) however, that Malcolm's observation is correct; and this paper is devoted to showing why it is correct. In the concluding section I present an account of dreaming that shows why it is that impossible dreams are possible.“What can a person dream?” This is an odd query; and what it might mean to put this question is not at all transparent. It is not like asking what a person might dream, when this is understood as a request for what someone is likely to dream, or what one may reasonably expect someone to dream, say, on the evening of a day in which one had visited a dentist.
