In recent decades, Russell’s “Neutral Monism” has reemerged as a topic of great scholarly interest among philosophers of mind, philosophers of science, and historians of early analytic philosophy. One of the most controversial points of scholarly dispute regarding Russell’s theory concerns how it best fits into standard classificatory schemes for understanding the relationship between mental phenomena and physical reality. The task of classifying Russell’s Neutral Monism is made all the more difficult by the fact that his conception of it evolves (...) in significant ways over the roughly four decades that he advocates it. In this paper, I contend that during this period, Russell holds (at least) three different, but related, ontological views, all of which he labels as “neutral monism”. This paper begins by considering key aspects of Russell’s early dualism which continue to play important roles in his Neutral Monism, especially his views about acquaintance, knowledge by description, structuralism about physics, and the construction of our physical knowledge. I argue that Russell revises, rather than abandons, his notion of knowledge by acquaintance in 1918 (when he gives up the act-object distinction) and contend that his resulting “neutral monism” remains a partial dualism until his 1921 The Analysis of Mind (hereafter AMi). Next, I explain how changes in physics leads Russell to re-conceptualize his Neutral Monism in The Analysis of Matter and An Outline of Philosophy, while challenging the relatively widespread view that his new position is a nonstandard version of physicalism. Finally, I argue that after 1940, Russell’s mature Neutral Monism—as presented in Human Knowledge: Its Scope and Limits, My Philosophical Development, and elsewhere—is very plausibly interpreted as a version of “Russellian Physicalism”.

"The Analysis of Matter" is one of the earliest and best philosophical studies of the new physics of relativity and quantum mechanics.

This paper starts from the assumption that panpsychism is counterintuitive and metaphysically demanding. A number of philosophers, whilst not denying these negative aspects of the view, think that panpsychism has in its favour that it offers a good explanation of consciousness. In opposition to this, the paper argues that panpsychism cannot help us to explain consciousness, at least not the kind of consciousness we have pre-theoretical reason to believe in.

In this paper, I argue that a number of recent Russell interpreters, including Evans, Davidson, Campbell, and Proops, mistakenly attribute to Russell what I call ‘the received view of acquaintance’: the view that acquaintance safeguards us from misidentifying the objects of our acquaintance. I contend that Russell’s discussions of phenomenal continua cases show that he does not accept the received view of acquaintance. I also show that the possibility of misidentifying the objects of acquaintance should be unsurprising given underappreciated aspects (...) of Russell’s overall theory of knowledge and acquaintance. Finally, I consider the radical impact that Russell’s actual views on acquaintance have for our understanding of his well-known George IV case in ‘On Denoting’. In particular, I argue that Russell’s treatment of the George IV case is not a one-size-fits-all solution to Frege’s Puzzle and provides no support for the received view of acquaintance. (shrink)

This paper is concerned with the question of the truth conditions of nomological statements. My fundamental thesis is that it is possible to set out an acceptable, noncircular account of the truth conditions of laws and nomological statements if and only if relations among universals - that is, among properties and relations, construed realistically - are taken as the truth-makers for such statements. My discussion will be restricted to strictly universal, nonstatistical laws. The reason for this limitation is not that (...) I feel there is anything dubious about the concept of a statistical law, nor that I feel that basic laws cannot be statistical. The reason is methodological. The case of strictly universal, nonstatistical laws would seem to be the simplest case. If the problem of the truth conditions of laws can be solved for this simple subcase, one can then investigate whether the solution can be extended to the more complex cases. I believe that the solution I propose here does have that property, though I shall not pursue that question here.1. (shrink)

Suppose that X and Y can’t possibly exist apart in reality; then—by definition—there’s no real distinction between them, only a conceptual distinction. There’s a conceptual distinction between a rectilinear figure’s triangularity and its trilaterality, for example, but no real distinction. In fundamental metaphysics there is no real distinction between an object’s categorical properties and its dispositional properties. So too there is no real distinction between an object and its properties. And in fundamental metaphysics, for X and Y to be such (...) that there is no real distinction between them is for them to be identical. (shrink)

If you’re a materialist, you probably think that rabbits are conscious. And you ought to think that. After all, rabbits are a lot like us, biologically and neurophysiologically. If you’re a materialist, you probably also think that conscious experience would be present in a wide range of naturally-evolved alien beings behaviorally very similar to us even if they are physiologically very different. And you ought to think that. After all, to deny it seems insupportable Earthly chauvinism. But a materialist who (...) accepts consciousness in weirdly formed aliens ought also to accept consciousness in spatially distributed group entities. If she then also accepts rabbit consciousness, she ought to accept the possibility of consciousness even in rather dumb group entities. Finally, the United States would seem to be a rather dumb group entity of the relevant sort. If we set aside our morphological prejudices against spatially distributed group entities, we can see that the United States has all the types of properties that materialists tend to regard as characteristic of conscious beings.

Kant once wrote, “Many historians of philosophy... let the philosophers speak mere nonsense.... They cannot see beyond what the philosophers actually said to what they really meant to say.’ Rae Langton begins her book with this quotation. She concludes it, after a final pithy summary of the position that she attributes to Kant, with the comment, “That, it seems to me, is what Kant said, and meant to say”. In between are some two hundred pages of admirably clear, tightly argued (...) exegesis, supplemented by detailed references, in which she offers what the dust jacket blurb fairly describes as “a new interpretation and defence of Kant’s doctrine of things in themselves.” This is an extremely engaging and thought-provoking book. I am pleased to recommend it. (shrink)

Rae Langton offers a new interpretation and defense of Kant's doctrine of things in themselves. Kant distinguishes things in themselves from phenomena, and in so doing he makes a metaphysical distinction between intrinsic and relational properties of substances. Langton argues that his claim that we have no knowledge of things in themselves is not idealism, but epistemic humility: we have no knowledge of the intrinsic properties of substances. This interpretation vindicates Kant's scientific realism, and shows his primary/secondary quality distinction to (...) be superior even to modern-day competitors. And it answers the famous charge that Kant's tale of things in themselves is one that makes itself untellable. (shrink)

This first volume contains discussions of the brain, methods for analyzing behavior, thought, consciousness, attention, association, time, and memory.

It is a traditional empiricist doctrine that natural laws are universal truths. In order to overcome the obvious difficulties with this equation most empiricists qualify it by proposing to equate laws with universal truths that play a certain role, or have a certain function, within the larger scientific enterprise. This view is examined in detail and rejected; it fails to account for a variety of features that laws are acknowledged to have. An alternative view is advanced in which laws are (...) expressed by singular statements of fact describing the relationship between universal properties and magnitudes. (shrink)

In which a scientist searches for an empirical explanation for phenomenal experience, spurred by his instinctual belief that life is meaningful. What links conscious experience of pain, joy, color, and smell to bioelectrical activity in the brain? How can anything physical give rise to nonphysical, subjective, conscious states? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. This engaging book--part scientific overview, part memoir, part futurist speculation--describes (...) Koch's search for an empirical explanation for consciousness. Koch recounts not only the birth of the modern science of consciousness but also the subterranean motivation for his quest--his instinctual belief that life is meaningful. Koch describes his own groundbreaking work with Francis Crick in the 1990s and 2000s and the gradual emergence of consciousness as a legitimate topic for scientific investigation. Present at this paradigm shift were Koch and a handful of colleagues, including Ned Block, David Chalmers, Stanislas Dehaene, Giulio Tononi, Wolf Singer, and others. Aiding and abetting it were new techniques to listen in on the activity of individual nerve cells, clinical studies, and brain-imaging technologies that allowed safe and noninvasive study of the human brain in action. Koch gives us stories from the front lines of modern research into the neurobiology of consciousness as well as his own reflections on a variety of topics, including the distinction between attention and awareness, the unconscious, how neurons respond to Homer Simpson, the physics and biology of free will, dogs, Der Ring des Nibelungen, sentient machines, the loss of his belief in a personal God, and sadness. All of them are signposts in the pursuit of his life's work--to uncover the roots of consciousness. (shrink)

The book is an extended study of the problem of consciousness. After setting up the problem, I argue that reductive explanation of consciousness is impossible , and that if one takes consciousness seriously, one has to go beyond a strict materialist framework. In the second half of the book, I move toward a positive theory of consciousness with fundamental laws linking the physical and the experiential in a systematic way. Finally, I use the ideas and arguments developed earlier to defend (...) a form of strong artificial intelligence and to analyze some problems in the foundations of quantum mechanics. (shrink)

First published in 1818, The World as Will and Representation contains Schopenhauer's entire philosophy, ranging through epistemology, metaphysics, philosophy of mind and action, aesthetics and philosophy of art, to ethics, the meaning of life and the philosophy of religion, in an attempt to account for the world in all its significant aspects. It gives a unique and influential account of what is and is not of value in existence, the striving and pain of the human condition and the possibility of (...) deliverance from it. This new translation of the first volume of what later became a two-volume work reflects the eloquence and power of Schopenhauer's prose and renders philosophical terms accurately and consistently. It offers an introduction, glossary of names and bibliography, and succinct editorial notes, including notes on the revisions of the text which Schopenhauer made in 1844 and 1859. (shrink)

Scientific Essentialism defends the view that the fundamental laws of nature depend on the essential properties of the things on which they are said to operate, and are therefore not independent of them. These laws are not imposed upon the world by God, the forces of nature or anything else, but rather are immanent in the world. Ellis argues that ours is a dynamic world consisting of more or less transient objects which are constantly interacting with each other, and whose (...) identities depend on their roles in these processes. Natural objects must behave as they do, because to do otherwise would be contrary to their natures. The laws of nature are, therefore, metaphysically necessary, and consequently, there are necessary connections between events. Brian Ellis calls for the rejection of the theory of Humean Supervenience and an implementation of a new kind of realism in philosophical analysis. (shrink)

Professional philosophers and advanced students working in metaphysics and the philosophy of science will find this book both provocative and stimulating.

How am I to account for this difficulty? I would like to be able to say that Cornman has simply misconstrued the appearances he is seeking to save, and that his subtle hypothetical-deductive theorizing rests on faulty "observation." Yet although I do think that he has misconstrued the views he is seeking to explain, and shall argue this in detail, I have come to see that I must bear a substantial part of the responsibility. He may have missed some clues (...) that were in front of his eyes, but often the passages with which he had to cope were unclear and indistinct. Relatively small errors of interpretation at the beginning of a commentary can snowball into major misunderstandings. This tendency is present in Cornman's essay; but his grasp of the general trend of my thinking has provided a constant corrective, and kept his hypotheses as close as they are to the truth. And, indeed, if I am disturbed at the difficulty he has found in reconstructing my thought, I derive some measure of encouragement from the fact that in the closing stages of his argument he is so close to formulating the position I have sought to defend, that had he been able to put his apparatus aside and take a fresh look at the evidence, he must have seen that some, at least, of the questions he pursues did not arise.

Consciousness fits uneasily into our conception of the natural world. On the most common conception of nature, the natural world is the physical world. But on the most common conception of consciousness, it is not easy to see how it could be part of the physical world. So it seems that to find a place for consciousness within the natural order, we must either revise our conception of consciousness, or revise our conception of nature. In twentieth-century philosophy, this dilemma is (...) posed most acutely in C. D. Broad’s The Mind and its Place in Nature . The phenomena of mind, for Broad, are the phenomena of consciousness. The central problem is that of locating mind with respect to the physical world. Broad’s exhaustive discussion of the problem culminates in a taxonomy of seventeen different views of the mental-physical relation.1 On Broad’s taxonomy, a view might see the mental as nonexistent , as reducible, as emergent, or as a basic property of a substance . The physical might be seen in one of the same four ways. So a four-by-four matrix of views results. At the end, three views are left standing: those on which mentality is an emergent characteristic of either a physical substance or a neutral substance, where in the latter case, the physical might be either emergent or delusive.

A number of popular arguments for dualism start from a premise about an epistemic gap between physical truths about truths about consciousness, and infer an ontological gap between physical processes and consciousness. Arguments of this sort include the conceivability argument, the knowledge argument, the explanatory-gap argument, and the property dualism argument. Such arguments are often resisted on the grounds that epistemic premises do not entail ontological conclusion. My view is that one can legitimately infer ontological conclusions from epistemic premises, if (...) one is very careful about how one reasons. To do so, the best way is to reason first from epistemic premises to modal conclusions , and from there to ontological conclusions. Here, the crucial issue is the link between the epistemic and modal domains. How can one reason from theses about what is knowable or conceivable to theses about what is necessary or possible? To bridge the epistemic and modal domains, the framework of two-dimensional semantics can play a central role. I have used this framework in earlier work to mount an argument against materialism. Here, I want to revisit the argument, laying it out in a more explicit and careful form, and responding to a number of objections. In what follows I will concentrate mostly on the conceivability argument. I think that very similar considerations apply to the other arguments mentioned above, however. In the final section of the paper, I show how this analysis might yield a unified treatment of a number of anti-materialist arguments. (shrink)
