What is consciousness?

In the past few years scientists and scholars in a variety of disciplines have been making concerted efforts to answer an ancient question, namely, How exactly do the physical processes in the brain cause consciousness? What is distinctive about the way in which modern scientists and scholars are approaching this question is that they are treating it as a scientific problem rather than a metaphysical one. This transition reflects the air of expectation in contemporary cognitive science to the effect that an empirical solution is imminent to a philosophical problem that previously was considered insoluble. Nevertheless, a recent authoritative review of the publications of such leading contemporary workers in the field as Francis Crick, Daniel Dennett, Gerald Edelman, Roger Penrose, and Israel Rosenfield has concluded that they have all failed to provide a satisfactory answer to the question (Searle 1995a). The present paper makes a psychoanalytic contribution to this interdisciplinary effort and provides an alternative answer to the question, based on Freud's conceptualization of the problem of consciousness. The paper takes a concrete example from Searle's review, reanalyses it within Freud's metapsychological frame of reference, and shows how this frame provides a radical solution to the problem. This implication of Freud's work has not hitherto been recognized and so has not received the attention it deserves.

Awareness

[What are affects?].

In an attempt to answer the question, "what is affect?", this paper considers Freud's metapsychological formulation in the light of recent developments in psychoanalysis and neuroscience. It argues that the problem of affect-perhaps more than any other-forces us to acknowledge the intrinsic connexion between mind and body, and to accommodate it in our theoretical formulations. A review of the problem from this point of view leads to the following formulation: affect is a primary sensory modality, analogous to the senses of vision, hearing, somatic sensation, taste, and smell. These modalities are the elementary constituents of the envelope of consciousness, from which it is impossible to free ourselves. Whereas the sensory modalities of vision, hearing, somatic sensation, taste, and smell represent aspects of the external object world ("unknowable" in itself), affect is the primary sensory modality through which we perceive as aspect of the internal world of the subject ("unconscious" in itself).

New findings on the neurological organization of dreaming: implications for psychoanalysis.

A recent clinico-anatomical study of the dreams of 332 neurological and neurosurgical patients suggests that the essential psychological processes of dreaming are mediated by higher forebrain structures (inferior parietal and mediobasal frontal lobes in particular) rather than the primitive brainstem nuclei which regulate REM sleep. The fundamental neuropsychological mechanisms involved in dreaming appear to be (1) inhibitory mental control, (2) spatial thought, and (3) quasi-spatial (symbolic) operations. The essential factor in REM sleep, by contrast, is basic arousal. These neuropsychological findings call into question prevailing theories (based on physiological evidence) of the relationship between dreaming and REM sleep. Dreams and REM appear to unfold over different anatomical structures, and they involve different psychological mechanisms. The implications of these findings for psychoanalysis are discussed in this paper.

Arousal

Three previously-untranslated reviews by Freud from the Neue Freie Presse.

Three short reviews by Freud (1904c, 1904d, 1905f) are presented in English translation. Two of the reviews, which are unusually harsh in their criticism, concern books on the subject of neurasthenia. The third relates to a controversial experiment on magnetism. The reviews were not included in the Standard Edition of Freud's psychological works, nor in any of the earlier collections of his writings.

A previously-untranslated report by Freud of a lecture on the mechanism of obsessional ideas and phobias.

This is an English translation of Freud's report of a lecture that he delivered in 1895 on the 'Mechanism of obsessional ideas and phobias'. The report was not included in the Standard Edition of Freud's psychological works, and nor was it included in any of the other collections of his writings. The lecture described in this report seems to have been derived directly from Freud's contemporaneous essay on 'Obsessions and phobias' (1895b). However there are a few discrepancies between the two, and these are discussed in the footnotes to the translation.

Freudian Theory

Inverted vision after frontal lobe disease.

A case of bifrontal abscesses is reported. The patient claimed that he sometimes saw the world as if it were upside-down. A review of the literature reveals that, since 1805, 21 similar cases have been documented. The present case is unusual in that the neuropsychological status of the patient is investigated in some detail, and in that it seems to be the first report of inverted vision in a case of frontal lobe disease.

On psychoanalysis and neuroscience: Freud's attitude to the localizationist tradition.

This study examines the relationship between psychoanalysis and neuroscience. It argues that the Project, the traditional starting-point for such an examination, provides few substantial links between Freud's neurological and psychoanalytic careers. The neurological model that the Project endorsed was not derived from Freud's formal neurological education, as has so often been assumed. It was based, instead, on the Jacksonian model that he developed in 'On aphasia' in 1891. 'On aphasia' appears to be the real 'missing link' between Freud's neurological and psychological years. The fundamental principles that it endorsed provided the framework within which psychoanalysis developed. After Freud's death, Luria developed the science of dynamic neuropsychology, which is based on the same fundamental neurological assumptions as 'On aphasia'. Dynamic neuropsychology approaches brain functioning in a way that would have been entirely acceptable to Freud. Considering the deep-rooted compatibility between Luria's neuropsychology and Freud's psychoanalysis, it would be beneficial for both sciences if they were to collaborate on issues of common interest. This makes Freud's lifelong ambition that psychoanalysis be rejoined with neuroscience a very real possibility.
