The relationship of consciousness to brain, which Schopenhauer grandly referred to as the "world knot," remains an unsolved problem within both philosophy and science. The central focus in what follows is the relevance of science---from psychoanalysis to neurophysiology and quantum physics-to the mind-brain puzzle. Many would argue that we have advanced little since the age of the Greek philosophers, and that the extraordinary accumulation of neuroscientific knowledge in this century has helped not at all. Increas- ingly, philosophers and scientists have (...) tended to go their separate ways in considering the issues, since they tend to differ in the questions that they ask, the data and ideas which are provided for consideration, their methods for answering these questions, and criteria for judging the acceptability of an answer. But it is our conviction that philosophers and scientists can usefully interchange, at least to the extent that they provide co~straints upon each other’s preferred strategies, and it may prove possible for more substantive progress to be made. Philosophers have said some rather naive things by ignoring the extraordinary advances in the neurosciences in the twentieth century. The skull is not filled with green cheese! On the other hand, the arrogance of many scientists toward philosophy and their faith in the scientific method is equally naive. Scientists clearly have much to learn from philosophy as an intellectual discipline. Manifestations of Mind: Some Conceptual and Empirical Issues Walter B.

Psychoanalysis often claims that an appraisal of its constituent hypotheses necessitates a personal analysis on the part of the critic with respect to the latter's ability to render a worthwhile and insightful evaluation of psychoanalytic theory. The objection to this position, namely one of ?privileged access?, has been voiced in numerous contexts, but a philosophical defense of the position has rarely been offered. In this paper such a defense is put forth, and it is argued that psychoanalysis is, in certain (...) crucial respects, analogous to physics in its scientific or structural respects, and insofar as this analogy holds, certain claims about one's familiarity with the latter also hold with respect to the former. Thus, a knowledge of physics entails an understanding of the laboratory procedures whereby physicists carry on their investigations. In the case of psychoanalysis certain ?laboratory operations? and ?instruments? are identifiable also. Where in the physics laboratory the physicist deals with cyclotrons, thermometers and the like, the psychoanalyst deals with the character traits of himself and the analysand. The character trait is the instrument whereby the analyst understands the analysand in a specifically psychoanalytic manner. Since the philosopher must know how the physicist works in the physics laboratory in order to understand physics, one must also understand the laboratory methodology of the analyst. Without the experience of psychoanalysis, however, such an understanding is truncated at best and nonexistent at worst. (shrink)

Georg Northoff encounters a problem regarding the logical status of “catatonia.” Whereas Parkinson's disease (PD) is a disease on the basis of Virchowian criteria, catatonia is not. PD is associated with pathognomonic neurological lesions. Catatonia does not require any such association. The diagnosis is rendered using social criteria rather than neuropathological ones. Therefore, Northoff is not comparing two disease states at all.
