Popper: Philosophy of Mind

In the light of a sketch of the history of modem Anti-Metaphysics up from Francis Bacon Wittgenstein's position - the refusal of the possibility of metaphysical assertions - is compared with the views of Mach, of Camap and Neurath and of Popper. Analysing the notions of 'nonsense', 'meaninglessness' and 'Scheinproblem', their interrelations and connections to physicalism three variants of Anti-Metaphysics are distinguished: the Enlightenment view, the positivistMachian view and the linguistic Wittgensteinian view. The present day actuality of these views is (...) evaluated and the conclusion drawn that the model of the cooperation between the different intellectual activities is more promising than the proscription of metaphysics.

Au sujet de la relation esprit-corps, Popper rejette le physicalisme, défini par le principe de clôture causale du domaine physique, et tente de construire une hypothèse interactionniste en accord avec la science contemporaine. Plus précisément, Popper reproche aux formes les plus élaborées du physicalisme d'entrer en contradiction avec la théorie de l'évolution, ainsi qu'avec le rationalisme. À l'opposé, il considère que l'hypothèse interactionniste peut se nourrir d'une comparaison minutieuse entre l'esprit et les forces physiques. Cette comparaison tend à rapprocher Popper (...) du panpsychisme. With respect to the mind-body relation, Popper rejects physicalism, as defined by the principle of the causal closure of the physical world, and attempts to build an interactionist hypothesis that would agree with the findings of contemporary science. More precisely, Popper criticizes the most elaborate forms of physicalism because they run counter to evolutionary theory and rationalism. By contrast, he thinks that the interactionist hypothesis can find support in a minute comparison of mind and physical forces. This comparison tends to draw Popper closer together with panpsychism.

Popper and Eccles present two different notions of Interactionism. Popper's arguments arise out of the traditional philosophical debate, whereas Eccles' arguments arise out of a mixture of neurophysiology and personal belief. Popper's three-world ontology is the philosophical foundation of both their positions. However, it is precisely against the background of the three Worlds that the considerable differences between their positions are apparent. Despite these defects, Interactionism is a productive notion since it does not place the Self beyond experimental investigation. Indeed, (...) both Popper and Eccles have made implicit suggestions as to experimental procedure which might contribute to the investigation of the Self. (shrink)

Popper, who was 92 when he died on 17 September 1994, was widely acclaimed as the greatest philosopher of science and by many as the greatest philosopher of any kind of the twentieth century. His most outstanding achievement was probably his solving of the age-old problem of induction . He showed that there is no such thing. Induction does not exist. Hume in his Treatise of Human Nature, 1739, had succeeeded in proving that experience and reason have no necessary connection (...) with one another . There is no such thing as rational belief. Kenneth Clark described this in his Civilisation as `an intellectual time bomb which, after sizzling away for almost two hundred years, has only just gone off.'. (shrink)

The survival and development of consciousness in biological evolution call for an explanation. An interactionistic mind-brain theory seems to have the greatest explanatory value in this context. An interpretation of an interactionistic hypothesis, recently proposed by Karl Popper, is discussed both theoretically and based on recent experimental data. In the interpretation, the distinction between the conscious mind and the brain is seen as a division into what is subjective and what is objective, and not as an ontological distinction between something (...) immaterial and something material. The interactionistic hypothesis is based on similarities between minds and physical forces. The conscious mind is understood to interact with randomly spontaneous spatio-temporal patterns of action potentials through an electromagnetic field. Consequences and suggestions for future studies are discussed. (shrink)

In this paper I describe basic features of traditional (British) emergentism and Popper’s emergentist theory of consciousness and compare them to the contemporary versions of emergentism present in connectionist approach in cognitive sciences. I argue that despite their similarities, the traditional form, as well as Popper’s theory belong to strong causal emergentism and yield radically different ontological consequences compared to the weaker, contemporary version present in cognitive science. Strong causal emergentism denies the causal closure of the physical domain and introduces (...) genuine new mental causal powers and genuine downward causation, while weak emergentism provides new insights in understanding the mechanisms and explanation that is compatible with physicalism.

One of the most influential thinkers of the 20th century, Sir Karl Popper here examines the problems connected with human freedom, creativity, rationality and the relationship between human beings and their actions. In this illuminating series of papers, Popper suggests a theory of mind-body interaction that relates to evolutionary emergence, human language and what he calls "the three worlds." Rene; Descartes first posited the existence of two worlds--the world of physical bodies and the world of mental states. Popper argues for (...) the existence of "world 3" which comprises the products of our human minds. He examines the interaction between mental states--hopes, needs, plans, ideologies or hypotheses--and the physical states of our brain. Popper forcefully argues against the materialism forwarded by many philosophers which denies the existence of mental states. Instead, he demonstrates that the problem of the interaction between mental and physical states remains unresolved. Knowledge and the Body-Mind Problem is based on Popper's never-before published lectures at Emory University in 1969. Popper has extensively revised the lectures but has retained their accessible format. He has also incorporated some of the discussions which followed the lectures, providing an engaging exchange between the philosopher and his audience. (shrink)

It is not a paper on linguistic analysis (the analysis of word-usages). For I completely reject the claim of certain language analysts that the source of philosophical difficulties is to be found in the misuse of language. No doubt some people talk nonsense, but I claim (a) that there does not exist a logical or language-analytical method of detecting philosophical nonsense (which, by the way, does not stop short of the ranks of logicians, language analysts and semanticists); (b) that the (...) belief that such a method exists -- the belief more especially that philosophical nonsense can be unmasked as due to what Russell might have called 'type-mistakes' and what nowadays are sometimes called 'category-mistakes' -- is the aftermath of a philosophy of language which has since turned out to be baseless.
