The relation between body and mind is one of the oldest riddles that has puzzled mankind. That material and mental events may interact is accepted even by the law: our mental capacity to concentrate on the task can be seriously reduced by drugs. Physical and chemical processes may act upon the mind; and when we are writing a difficult letter, our mind acts upon our body and, through a chain of physical events, upon the mind of the recipient of the (...) letter. This is what the authors of this book call the 'interaction of mental and physical events'. We know very little about this interaction; and according to recent philosophical fashions this is explained by the alleged fact that we have brains but no thoughts. The authors of this book stress that they cannot solve the body mind problem; but they hope that they have been able to shed new light on it. Eccles especially with his theory that the brain is a detector and amplifier; a theory that has given rise to important new developments, including new and exciting experiments; and Popper with his highly controversial theory of 'World 3'. They show that certain fashionable solutions which have been offered fail to understand the seriousness of the problems of the emergence of life, or consciousness and of the creativity of our minds. In Part I, Popper discusses the philosophical issue between dualist or even pluralist interaction on the one side, and materialism and parallelism on the other. There is also a historical review of these issues. In Part II, Eccles examines the mind from the neurological standpoint: the structure of the brain and its functional performance under normal as well as abnormal circumstances. The result is a radical and intriguing hypothesis on the interaction between mental events and detailed neurological occurrences in the cerebral cortex. Part III, based on twelve recorded conversations, reflects the exciting exchange between the authors as they attempt to come to terms with their opinions. (shrink)

The planninnjg of this Study Week at the Pontifical Academy of Science from September 28 to October 4, 1964, began just two years before when the President, Professor Lemaitre, asked me if 1 would be responsible for a Study Week relating Psychology to what we may call the Neurosciences. 1 accepted this responsibility on the understanding that 1 could have as sistance from two colleagues in the Academy, Professors Heymans and Chagas. Besides participating in the Study Week they gave me (...) much needed assistance and advice in the arduous and, at times, perplexing task that 1 had undertaken, and 1 gratefully acknowledge my indebtedness to them. Though there have been in recent years many symposia concerned with the so-called higher functions of the brain, for example witbh percep tion, learning and conditioning, and with the processing of information in the brain, there has to my knowledge been no symposium specifically with brain functions and consciousness since the memorable treating Laurentian Conference of 1953, which was later published in 1954 as the book, "Brain Mechanisms and Consciousness.

The materialist critics argue that insuperable difficulties are encountered by the hypothesis that immaterial mental events such as thinking can act in any way on material structures such as neurons of the cerebral cortex, as is diagrammed in Fig. 8. Such a presumed action is alleged to be incompatible with the conservation laws of physics, in particular of the First Law of Thermodynamics. This objection would certainly be sustained by 19th century physicists and by neuroscientists and philosophers who are still (...) ideologically in the physics of the 19th century, not recognizing the revolution wrought by quantum physicists in the 20th century. Unfortunately it is rare for a quantum physicist to dare an intrusion into the brain-mind problem. But in a recent book the quantum physicist Margenau (1984) makes a fundamental contribution. It is a remarkable transformation from 19th century physics to be told (p. 22): "that some fields, such as the probability field of quantum mechanics carry neither energy nor matter." He goes on (p. 96) to state: "In very complicated physical systems such as the brain, the neurons and sense organs, whose constituents are small enough to be governed by probabilistic quantum laws, the physical organ is always poised for a multitude of possible changes, each with a definite probability; if one change takes place that requires energy, or more or less energy than another, the intricate organism furnishes it automatically. Hence, even if the mind has anything to do with the change, that is if there is a mind-body interaction, the mind would not be called upon to furnish energy." In summary (p. 97) Margenau states that: "The mind may be regarded as a field in the accepted physical sense of the term. But it is a nonmaterial field; its closest analogue is perhaps a probability field. It cannot be compared with the simpler nonmaterial fields that require the presence of matter (e.g. gravity) nor does it necessarily have a definite position in space. And so far as present evidence goes it is not an energy field in any physical sense, nor is it required to contain energy in order to account for all known phenomena in which mind interacts with brain". In formulating more precisely the dualist hypothesis of mind-brain interaction, the initial statement is that the whole world of mental events (World 2) has an existence as autonomous as the world of matter-energy (World I ) (Fig. 1). The present interactionist hypothesis does not relate to these ontological problems, but merely to the mode of action of mental events on neural events, that is of the nature of the downward arrows across the frontier in Fig. 8. Following Margenau (1984) the hypothesis is that mind-brain interaction is analogous to a probability field of quantum mechanics, which has neither mass nor energy, yet can cause effective action at microsites. More specifically it is proposed that the mental concentration involved in intentions (Figs. 7, 8) or attention (Fig. 4) or planned thinking (Figs. 5, 6) can cause neural events by a process analogous to the probability fields of quantum mechanics. -/- We can ask: what neural events could be appropriate recipients for mental fields that are analogous to quantal probability fields? Already we may have the answer in recent discoveries on the nature of the synaptic mechanism whereby one nerve cell communicates with another. (shrink)

Traces the development of the human consciousness and argues that many scientific theories of human nature denigrate the value of humanity.

This paper focuses on the issue of justice as a challenge facing business and society. I advance a simple deductive argument based on two premises. The first emerges out of theories of justice and holds that fairness, as a foundational basis for justice, demands impartiality or the avoidance of bias. The second emerges out of fiduciary law and holds that the duty of loyalty owed by managers to serve the interests of investors is fundamentally partial or biased. The conclusion is (...) the troubling fact that the fiduciary duty of loyalty owed by managers to serve the interests of investors appears to be incompatible with the demands of justice. Having presented this, I describe the impartiality tools of Rawls’ veil of ignorance and Adam Smith’s impartial spectator and discuss how these might be applied in this context. I speculate that while Smith’s impartial spectator is absolutely incommensurable with managers’ fiduciary duty of loyalty, Rawls’ veil of ignorance might be used to imagine a synthesis between this duty of loyalty and the impartiality demands of justice – in theory at least. And finally, as a parting shot, I wonder whether the real “Leadership Challenge that Matters” isn’t the gap between theory and reality. (shrink)

Karl Bühler hat zur Entwicklung von Karl Poppers Forschungsgebieten drei wichtige Beiträge geleistet. Erstens hat er Popper in die laufende Forschung der Mitglieder der Würzburger Schule eingeführt, und die Richtung dieser Forschung hat in wichtigen Punkten Popper ein Leben lang beeinflusst. Dabei hatte er sich zunächst die nicht-assoziative Psychologie der Schule zu eigen gemacht. Dann griff er auf die Denkpsychologie von Otto Selz zurück und entwickelte davon ausgehend sein eigenes Forschungsgebiet der Methodologie. Zweitens betrafen die damals behandelten Probleme auch methodologische (...) Fragen: Wie ist die Beziehung zwischen Logik und Psychologie? Wie ist eine deduktivistische Methodologie möglich? Drittens hat Bühler ihn eine Zwei-Welten-Theorie gelehrt. Heinrich Gomperz war der erste, der Popper darauf hinwies, dass er bereits davon ausgegangen war, dass Ideen unabhängige Entitäten sind. Diese Entitäten hat er dann viel später mit John Eccles als Teile der dritten Welt bezeichnet. Auch als Gesprächspartner war Gomperz für Popper wichtig, insofern als Popper versuchte, eine klare Theorie über die Beziehungen zwischen Psychologie und Logik und danach zwischen Psychologie und Methodologie zu finden. Und Gomperz war es auch, der Poppers Augenmerk auf die Geschichte der griechischen Philosophie lenkte und ihm den großen Unterschied zwischen Platon und Sokrates klarmachte. (shrink)

In elite sport, the advantages demonstrated by expert performers over novices are sometimes due in part to their superior physical fitness or to their greater technical precision in executing specialist motor skills. However at the very highest levels, all competitors typically share extraordinary physical capacities and have supremely well-honed techniques. Among the extra factors which can differentiate between the best performers, psychological skills are paramount. These range from the capacities to cope under pressure and to bounce back from setbacks, to (...) the knowledge of themselves, opponents, and the domain, which experts access and apply in performance. In the companion chapter on breadth and depth of knowledge in expert sport (see Chapter 11), we discussed the forms or kinds of knowledge deployed by elite athletes, and described some lines of research which seek to tap and study such expert knowledge (McPherson & MacMahon, 2008; McRobert, Ward, Eccles & Williams, 2011). In this chapter we focus more directly on questions about methods for measuring or more accurately assessing expert knowledge, in particular addressing a wider range of methods to help us understand what experts know. Suggesting that sport researchers can productively adopt and adapt existing qualitative methodologies for integration with more standard quantitative methods, we introduce and survey a number of areas of qualitative research in psychology.
