    This document consists primarily of an excerpt (chapter 13) from the author’s book From Brain to Cosmos. In that excerpt, the author presents a study of the notion of truth using the concept of subjective fact developed earlier in the book. The author argues that mind-body materialism is compatible with certain forms of metaphysical idealism. The chapter closes with some remarks on relativism with regard to truth. (This document depends heavily upon the concept of subjective fact developed in Fr…Read more

    This document consists primarily of an excerpt (chapter 5) from the author’s book From Brain to Cosmos. That excerpt presents an analysis of personal identity through time, using the concept of subjective fact that the author developed earlier in the book. (Readers unfamiliar with that concept are strongly advised to read chapters 2 and 3 of From Brain to Cosmos first. See the last page of this document for details on how to obtain those chapters.)

    This short e-book is (in the author's words) "an attempt to open up new and better ways of thinking about God." The author draws together insights from philosophy of religion, philosophy of mind, and ontology to construct a conception of God that avoids both supernaturalism and simplistic forms of pantheism.

    The year is 1965. A child stands at the top of a hill, looking out over a vast golden meadow. In the field below is a dirt trail. Bicycles sail by on the trail, carrying other children to their playful destinations. Beyond the far edge of the field is the sea. On the sea are boats and ships — distant descendants of the caravels and barkentines that once explored the unknown waters of Earth.

    This is not a normal book. It is a collection of transcripts of talks that I gave between the year 2003 and now. I gave most of these talks on the spur of the moment, without making notes ahead of time. (“Impromptu” is the usual term for that dangerous way of speaking.) One of the “talks” is not a transcript, but a set of notes for a talk I never gave. Any organization or order in the talks is purely coincidental—or at least it’s not all my fault.

    Lewis's Modal Realism: a Reply to Naylor
    Analysis 48 (1): 13-15. 1988.

    This note is a reply to margery bedford naylor's "a note on david lewis's realism about possible worlds" . naylor asks why, if we accept david lewis's argument for real possible worlds , we should not accept an analogous argument for impossible worlds. i argue that the latter argument is invalid on the modal realist account of possibility and thus has no force for an adherent of lewis

    One of the most important ongoing debates in the philosophy of mind is the debate over the reality of the first-person character of consciousness.[1] Philosophers on one side of this debate hold that some features of experience are accessible only from a first-person standpoint. Some members of this camp, notably Frank Jackson, have maintained that epiphenomenal properties play roles in consciousness [2]; others, notably John R. Searle, have rejected dualism and regarded mental phenomena as enti…Read more

    Cortical feedback and the ineffability of colors
    PSYCHE: An Interdisciplinary Journal of Research On Consciousness 11. 2005.
    Philosophers long have noted that some sensations (particularly those of color) seem to be ineffable, or refractory to verbal description. Some proposed neurophysiological explanations of this ineffability deny the intuitive view that sensations have inherently indescribable content. The present paper suggests a new explanation of ineffability that does not have this deflationary consequence. According to the hypothesis presented here, feedback modulation of information flow in the cortex interf…Read more

    Proper classes via the iterative conception of set
    Journal of Symbolic Logic 52 (3): 636-650. 1987.
    We describe a first-order theory of generalized sets intended to allow a similar treatment of sets and proper classes. The theory is motivated by the iterative conception of set. It has a ternary membership symbol interpreted as membership relative to a set-building step. Set and proper class are defined notions. We prove that sets and proper classes with a defined membership form an inner model of Bernays-Morse class theory. We extend ordinal and cardinal notions to generalized sets and prove o…Read more

    Chemical elements and the problem of universals
    Foundations of Chemistry 8 (3): 225-242. 2006.
    In this paper, I explore a seldom-recognized connection between the ontology of abstract objects and a current issue in the philosophy of chemistry. Specifically, I argue that realism with regard to universals implies a view of chemical elements similar to F.A. Paneth’s thesis about the dual nature of the concept of element.

    Broadening the Iterative Conception of Set
    Notre Dame Journal of Formal Logic 42 (3): 149-170. 2001.
    The iterative conception of set commonly is regarded as supporting the axioms of Zermelo-Fraenkel set theory (ZF). This paper presents a modified version of the iterative conception of set and explores the consequences of that modified version for set theory. The modified conception maintains most of the features of the iterative conception of set, but allows for some non-wellfounded sets. It is suggested that this modified iterative conception of set supports the axioms of Quine's set theory NF

    is not about traditional skeptical thinkers like Descartes and Hume. Instead, it is about some of the ideas of today’s ”skeptics” — people who try to debunk things that seem too odd or too spiritual. This site is not meant to encourage weird beliefs, but it might make you wonder whether skepticism is a weird belief too

    Many people regard the mind as something separate from the body. This includes many religious believers, who regard personality and self as attributes of an immortal soul. Some philosophers, relying on logic instead of faith, also have taken the position that the mind is distinct from the body and is not explainable in terms of bodily processes alone. The belief that a person is composed of a mind and a body, with neither one reducible to the other, has traditionally been called dualism.

    The twentieth century was a century of progress. During those hundred years, humanity progressed from a world without airplanes, computers, or modern medicine to a new era in which these technological miracles were commonplace. These technical achievements were not the only accomplishments of that fateful century. There also were vast changes in social thought, with great steps forward toward human equality and freedom — the struggle for racial equality, the recognition of women's rights, and th…Read more
