What is consciousness? What is its importance and how is it to be described? The paper looks at some of the principal theories and their attempts to solve the “hard problem” of how consciousness is produced by nervous tissue, and attempts to close the “explanatory gap” between such (apparently) profoundly different things as subjective awareness and a physical brain. It ends with a tentative suggestion that, despite centuries of philosophical frustration, recent appeals to quantum physics may offer a glimmer of (...) hope. (shrink)

The recently celebrated division into ‘easy’ and ‘hard’ problems of consciousness is unfortunate and misleading. Built on functionalist grounds, it carves up the subject matter by declaring that the most elusive parts need a fundamentally and intrinsically different solution. What we have, rather, are ‘difficult’ problems of conscious experience, but problems that are not difficult per se. Their difficulty is relative, among other things, to the kind of solution one is looking for and the tools used to accomplish the task. (...) I argue that the study of conscious experience in our scientific and philosophical tradition is a very difficult problem because it has been addressed with inappropriate tools: with harmful long-lasting and inadequate dogmas that have dogged science for centuries. I describe five of these dogmas, which are: the existence of an objective reality independent of human understanding; the subordination of epistemology to ontology; the restricted view of the objectivist-subjectivist dichotomy; the exclusion of the body from the study of the mind; and the idea of explaining the mind in terms of the neurophysiological processes of individual brains. I claim that conscious experience is not a transcendental, paranatural, mystic or magic phenomenon. It is tractable and approachable with scientific methods. However, one must look not only for non-reductionist views to approach it, but also for views that avoid the dogmas here described. Conscious experience is a living phenomenon and it has to be understood as such. Accordingly, our understanding of it has to make sense at several levels, from evolution to morphophysiology, from neuroanatomy to language. I put forward an approach to conscious experience which is free of the dogmas that make the study of conscious experience so difficult. This view, called ecological naturalism, is a non-functionalist and non-reductive view that provides an naturalistic account of the mind. It also puts special emphasis on irreducible supra-individual biological processes that are essential in the realization of mental phenomena and therefore conscious experience. (shrink)

The late 19th-century Ignorabimus controversy over the limits of scientific knowledge has often been characterized as proclaiming the end of intellectual progress, and by implication, as plunging Germany into a crisis of pessimism from which Liberalism never recovered. My research supports the opposite interpretation. The initiator of the Ignorabimus controversy, Emil du Bois-Reymond, was a physiologist who worked his whole life against the forces of obscurantism, whether they came from the Catholic and Conservative Right or the scientistic and millenarian Left. (...) Du Bois-Reymond’s doubt that scientists would ever elucidate consciousness must therefore be seen as an endorsement, and not a rejection, of his faith in reason. (shrink)
