In a recent article (Inquiry, Vol. 19 [1976]), J. W. Meiland addresses the issue of psychologism in logic, which holds that logic is a branch of psychology and that logical laws (such as the Principle of Non?Contradiction) are contingent upon the nature of the mind. Meiland examines Husserl's critique of psychologism, argues that Husserl is not convincing, and offers two new objections to the psychologistic thesis. In this paper I attempt to rebut those objections. In question are the acceptable criteria (...) for determining the possibility or impossibility of systems of logic significantly different from our own. I argue that a criteriological application of our accepted laws of logic to this question commits a circular fallacy. I then argue that, even if we accept logical consistency as a criterion for possibility, a plausible argument for the possibility of valid alternative logics can be constructed by using the functionalist analogy between minds and automata. Finally, I attempt to rebut the claim that in logic the only changes possible are conceptual changes that would not permit a proposition to be both true and false. (shrink)

Some philosophers suspect that the functionalist account of mind supports a psychologistic account of logic. One who has argued for a connection of this kind is Remmel T. Nunn. If the connection holds, it might be a powerful support for the currently unfashionable position of psychologism; conversely, it might be a damaging objection to functionalism. In either case, to estabjish the connection would be an achievement of considerable philosophic interest.

For this year’s Virtual Issue, our guest editor, Omar W. Nasim, has collected together papers from the Aristotelian Society archives that represent a substantial part of a dispute that contributed to the emergence of analytic philosophy in Britain at the turn of the 20th Century. The dispute was primarily concerned with the problem of the external world – the nature of the sensible objects of perception, and how they relate to physical things and the perceiving subject. The participants in this (...) controversy contested the nature of the appearance-reality distinction, whether it is it is possible for a thing to instantiate contrary sensible qualities at the same place and time, the distinction between presentation and representation, the nature of knowledge by acquaintance, and the nature of sense-data – e.g., whether sense-data are psychical or physical, whether they persist unperceived, and how they give rise to knowledge of the external world. G. E. Moore and Bertrand Russell were significant contributors to these debates, but so too were several philosophers whose names are now less well known: G. F. Stout, G. Dawes Hicks, Abraham Wolf, T. Percy Nunn, and S. Alexander. This Virtual Issue collects together, for the first time, the important contributions made to these debates by all of these figures. In doing so it provides a fascinating insight into the ways in which Russell’s earliest attempts to construct the external world from sense-data were influenced by the ideas and arguments of his immediate contemporaries. Omar W. Nasim’s specially commissioned introduction to the Virtual Issue sets out the historical context of these disputes about the external world, and details the prominent role played by the Aristotelian Society in making them possible.

Analogy with the monisms of fundamental physics suggests that a concept of symmetry breaking is likely to help towards developing an understanding of mind/matter monism. I explore some possible consequences of this concept, arguing that a broken symmetry, involving energy and 'what-it-is-like-to-be-ness'along with time, may occur and may manifest in the course of energy measurements. The resultant proto-panpsychist picture has the advantage of indicating how our complex, human consciousness could emerge from proto-conscious elements. It's an account that has empirical, refutable (...) implications which are briefly discussed. (shrink)

Annotation Up-to-date and accessible examination of scientific thinking about the nature of consciousness. Chris Nunn sets out the most exciting theoretical and experimental advances in this fast developing and controversial area.

This book is about how we make choices. It is a compelling analysis of the nature of free will, drawing together evidence from chemistry, literature, politics, history and beyond. Psychiatrist Chris Nunn elegantly explores the revolutions in medicine, genetics, bioethics and neuroscience spurred by Julien de la Mettrie's 300-year-old tract Man the Machine . Nunn concludes that a mechanistic view of the human brain, though once fruitful, is now moribund. He proposes a powerful alternative: that stories, recorded in (...) our memories throughout life, are the mediators of free choice. Nunn demonstrates how this original approach could reconcile the latest brain-imaging results and our seemingly contradictory intuition about decision making and responsibility. (shrink)

Here is an account of mentality and human experience, written for a multi-disciplinary readership. The focus is on how mind, consciousness and selves inter-relate, extending into exploration of ideas about the nature of awareness and a search for relevant evidence.‘Consciousness studies’ has reached something of a crossroads nowadays. Computational approaches to mind and ‘quantum consciousness’ theories, have not lived up to early hopes. Neuroscience has made huge strides in the last few years, but is still nowhere near able to account (...) for the existence of consciousness itself - as opposed to being able to explain how some of its content gets there. Philosophically, there is lack of consensus over both the nature of consciousness and what questions we should be asking about it.Chris Nunn's book surveys the current situation and argues that, as far as ‘mind’ is concerned, we need to take the overall dynamics into consideration, which include genetic, environmental and social factors along with neurology. He emphasizes the close links that exist between memory, experience and personhood. What emerges most strongly from this account is that answers to questions about the nature of consciousness are likely to depend on achieving a better understanding of the physics of time.Chris Nunn is a psychiatrist who researched mind/body relationships and bipolar disorder. He has been involved in the ‘consciousness studies’ movement since 1992. (shrink)
