Darwinized Hegelianism or Hegelianized Darwinism? 1 Darwinized Hegelianism or Hegelianized Darwinism? Mathias Girel 1 It has been said that Peirce was literally talking “with the rifle rather than with the shot gun or water hose” (Perry 1935, vol. 2: 109). Readers of his review of James’s Principles can easily understand why. In some respects, the same might be true of the series of four books Joseph Margolis has been devoting to pragmatism since 2000. One of the first targets of Margolis’s rereading was the very idea of a ‘revival’ of pragmatism (a ‘revival’ of something that never was, in some ways), and, with it, the idea that the long quarrel between Rorty and Putnam was really a quarrel over pragmatism (that is was a pragmatist revival, in some ways). The uncanny thing is that, the more one read the savory chapters of the four books, the more one feels that the hunting season is open, but that the game is not of the usual kind and looks more like zombies, so to speak.

Reflexive Monism
Reflexive Monism Max Velmans, Goldsmiths, University of London; email [email protected]; http://www.goldsmiths.ac.uk/psychology/staff/velmans.php Journal of Consciousness Studies (2008), 15(2), 5-50. Abstract. Reflexive monism is, in essence, an ancient view of how consciousness relates to the material world that has, in recent decades, been resurrected in modern form. In this paper I discuss how some of its basic features differ from both dualism and variants of physicalist and functionalist reductionism, focusing on those aspects of the theory that challenge deeply rooted presuppositions in current Western thought. I pay particular attention to the ontological status and seeming “out- thereness” of the phenomenal world and to how the “phenomenal world” relates to the “physical world”, the “world itself”, and processing in the brain. In order to place the theory within the context of current thought and debate, I address questions that have been raised about reflexive monism in recent commentaries and also evaluate competing accounts of the same issues offered by “transparency theory” and by “biological naturalism”. I argue that, of the competing views on offer, reflexive monism most closely follows the contours of ordinary experience, the findings of science, and common sense. Key words: Consciousness, reflexive, monism, dualism, reductionism, physicalism, functionalism, transparency, biological naturalism, phenomenal world, physical world, world itself, universe itself, brain, perceptual projection, phenomenal space, measured space, physical space, space perception, information, virtual reality, hologram, phenomenological internalism, phenomenological externalism, first person, third person, complementary What is Reflexive Monism? Monism is the view that the universe, at the deepest level of analysis, is one thing, or composed of one fundamental kind of stuff.

SEARLE'S BIOLOGICAL NATURALISM AND THE ARGUMENT FROM CONSCIOUSNESS J. P. Moreland In recent years, Robert Adams and Richard Swinburne have developed an argument for God's existence from the reality of mental phenomena. Call this the argument from consciousness (AC). My purpose is to develop and defend AC and to use it as a rival paradigm to critique John Searle's biological natural ism. The article is developed in three steps. First, two issues relevant to the epistemic task of adjudicating between rival scientific paradigms (basicality and naturalness) are clarified and illustrated. Second, I present a general ver sion of AC and identify the premises most likely to come under attack by philosophical naturalists. Third, I use the insights gained in steps one and two to criticize Searle's claim that he has developed an adequate naturalistic theory of the emergence of mental entities.

A Traditional Scientific Perspective on the Integrated Information Theory Of
entropy Article A Traditional Scientific Perspective on the Integrated Information Theory of Consciousness Jon Mallatt The University of Washington WWAMI Medical Education Program at The University of Idaho, Moscow, ID 83844, USA; [email protected] Abstract: This paper assesses two different theories for explaining consciousness, a phenomenon that is widely considered amenable to scientific investigation despite its puzzling subjective aspects. I focus on Integrated Information Theory (IIT), which says that consciousness is integrated information (as φMax) and says even simple systems with interacting parts possess some consciousness. First, I evaluate IIT on its own merits. Second, I compare it to a more traditionally derived theory called Neurobiological Naturalism (NN), which says consciousness is an evolved, emergent feature of complex brains. Comparing these theories is informative because it reveals strengths and weaknesses of each, thereby suggesting better ways to study consciousness in the future. IIT’s strengths are the reasonable axioms at its core; its strong logic and mathematical formalism; its creative “experience- first” approach to studying consciousness; the way it avoids the mind-body (“hard”) problem; its consistency with evolutionary theory; and its many scientifically testable predictions. The potential weakness of IIT is that it contains stretches of logic-based reasoning that were not checked against hard evidence when the theory was being constructed, whereas scientific arguments require such supporting evidence to keep the reasoning on course. This is less of a concern for the other theory, NN, because it incorporated evidence much earlier in its construction process. NN is a less mature theory than IIT, less formalized and quantitative, and less well tested.

Lecture 24 Biological Naturalism About the Lecture
Lecture 24 Biological Naturalism About the Lecture: Biological naturalism is a philosophical theory of the mind. Itputs the problem of mind-body dualism and the related context of consciousness in a new perspective. It provides a broad naturalistic framework for the explanation of consciousness and other mental phenomena. The theory is based on the hypothesis that mental phenomena are caused by and realized in the brain processes.This theory is a part of a biological worldview and this worldview is based on the theory of evolution. The human life is manifested in the evolutionary process of the universe. On the other hand, the natural aspect of the theory shows that the brain, as the central part of the human organism causes mental life. The mental life is comprised of both conscious and unconscious activities of the brain. The conscious aspects include conscious and unconscious mental states along with their basic features, like intentionality, subjectivity, free will, etc. whereas the unconscious aspects of brain signify its neurophysiological functions. Key words: Naturalism, Mind-Body Dualism, Causal Relation, Emergence, Micro and macro level. Biological naturalism as a theory of mind puts the problem of mind-body dualism and the related context of consciousness in a new perspective. It provides a broad naturalistic framework for the explanation of consciousness and other mental phenomena. The theory is based on the hypothesis that mental phenomena are caused by and realized in the brain processes. Moreover, as Searle defines his theory, “Mental phenomena are caused by the neurophysiological processes in the brain and are themselves features of the brain.

The Logical Foundations of Democratic Dogma' I
THE LOGICAL FOUNDATIONS OF DEMOCRATIC DOGMA’ I SCIENCE AND MAN: THE DEGRADATION OF SCIENTIFIC DOGMA I. INTRODUCTION A are doubtless wondering why, in this time of stress Youand strain, a philosopher of all men should be asked to speak to you. And you have a right to wonder. If, as the ancient Roman dictum has it, inter arma leges silent, even more in such times should the philosopher withdraw into silence and leave the field to better men. For this is not the time, it will be said, for abstract thought and balanced judg- ment, but for emotion and action. And yet a strong case can be made out for the opposite. If in time of war laws are silent it is just at such a time that the law should speak most majestically. If in time of war unreason is in the saddle it is at such a time that man, if he is to remain man and not sink to the level of the beast, should think most about reason and rationality. “The philosopher,” wrote William James, “is simply a man who thinks a little more stubbornly than other people.” It is, however, not merely this stubbornness that distin- guishes the philosopher but rather what all his stubborn- 1A course of three public lectures delivered at the Rice Institute, February 22, 24, and 26, 191.3, by Wilbur Marshall Urban, Dr. Phil., L.H.D., Pro- fessor of Philosophy, Emeritus, at Yale University.

1 Why I Am Not a Property Dualist by John R. Searle I Have Argued in a Number of Writings1 That the Philosophical Part (Though
1 Why I Am Not a Property Dualist By John R. Searle I have argued in a number of writings1 that the philosophical part (though not the neurobiological part) of the traditional mind-body problem has a fairly simple and obvious solution: All of our mental phenomena are caused by lower level neuronal processes in the brain and are themselves realized in the brain as higher level, or system, features. The form of causation is “bottom up,” whereby the behavior of lower level elements, presumably neurons and synapses, causes the higher level or system features of consciousness and intentionality. (This form of causation, by the way, is common in nature; for example, the higher level feature of solidity is causally explained by the behavior of the lower level elements, the molecules.) Because this view emphasizes the biological character of the mental, and because it treats mental phenomena as ordinary parts of nature, I have labeled it “biological naturalism.” To many people biological naturalism looks a lot like property dualism. Because I believe property dualism is mistaken, I would like to try to clarify the differences between the two accounts and try to expose the weaknesses in property dualism. This short paper then has the two subjects expressed by the double meanings in its title: why my views are not the same as property dualism, and why I find property dualism unacceptable. There are, of course, several different “mind-body” problems. The one that most concerns me in this article is the relationship between consciousness and brain processes. I think that the conclusions of the discussion will extend to other features of the mind-body problem, such as, for example, the relationship between intentionality and brain processes, but for the sake of simplicity I will concentrate on consciousness.

Metaphysical Naturalism and the Ignorance of Categorical Properties
Copyright © 2017 by Lok-Chi Chan Thesis supervisor: Professor David Braddon-Mitchell Department of Philosophy, The University of Sydney Cover design: Chan Man Yuk i Declaration I certify that the intellectual content of this thesis is the product of my own work. Assistance received in preparing this thesis and sources have been acknowledged. Lok-Chi Chan ii Abstract The purpose of this dissertation is to investigate the connections between metaphysical naturalism and the categorical ignorance thesis – offered by Rae Langton (1998), David Lewis (2009), Frank Jackson (1998), and Simon Blackburn (1990) – and determine whether the latter will challenge the former. According to metaphysical naturalism, the actual world contains only metaphysically natural things. According to the categorical ignorance thesis, all we can know about things are their dispositional properties, but the categorical properties that bear these properties remain in principle unknowable. In this dissertation, I will determine whether the ignorance of categorical properties – as Rae Langton (1998), David Braddon-Mitchell and Frank Jackson (2007), John Foster (1993) and Alyssa Ney (2007) argue (or worry about) – is consistent with metaphysical naturalism (or physicalism), and whether it will lead to a scepticism about the metaphysical naturalness of categorical properties, which will, in turn, significantly decrease the probability that metaphysical naturalism is true. Being attracted to metaphysical naturalism, the categorical ignorance thesis, and also the philosophical position that the two theses are consistent, I will argue that the answer to the former question is yes, and that the answer to the latter question is no. Russellian Monism, an influential doctrine in philosophy of mind that is relevant to the topic, will also be considered.

John Rogers Searle's Biological Naturalism

I ||August. 2018 || PP.01-03 John Rogers Searle’s Biological Naturalism: A Defense Of Traditional Mind-Body Problem Soumya. A.S. Assistant Professor Department of Philosophy Sree Keralavarma College Thrissur, Kerala. Corresponding Author: Soumya. A.S. ABSTRACT: Even in recent times majority among the neurobiologists do not regard consciousness as a suitable topic for scientific investigation. This disinclination is based on certain philosophical mistakes. There is this assumption that the subjectivity of consciousness made it beyond the reach of an objective science. Once we see that consciousness is a biological phenomenon like any other, it can be investigated neurobiologically. Viewed empirically Consciousness is a phenomenon entirely caused by neurobiological processes and is realized in brain structures. An important quality of consciousness we need to unlock is the unified qualitative subjectivity. In other words Consciousness differs from other biological phenomena since it has a subjective or first-person ontology. It is claimed that this subjective ontology does not prevent us from having an epistemically objective science of consciousness, and this seems essential if we need to overcome the philosophical tradition that treats the mental and the physical as two distinct metaphysical realms. Such an attempt has been made by John Searle and his popular attempt to resolve mind-body problem known as Biological Naturalism. The present paper intends to site Searle’s attempt to resolve the puzzles in consciousness research as setting a new orientation for research in this area.

Dualism, False Monism and Proper Monism
Towards a Proper Monism Filip Radovic Dept. of Philosophy, Göteborg University Poster presentation at: Toward a Science of Consciousness, Tucson III April 27-May 2, 1998, Tucson, Arizona, USA Contents: 1. Summary 2. Introduction 3. False and proper monism 4. A note on Descartes´ demarcation of the mental and the physical 5. "Phenomenal experience" as a complementary contrast term 6. The exaggerated emphasis on the subjective character of mind 7. The assumed status of "qualia" as a folk-psychological notion 8. Can we solve the mind-body problem? References 1. Summary My analysis of the mind-body problem suggests that the mind-body problem is a "problem" because: • There are discrepancies in use between scientific notions like "physical" and philosophical notions like "phenomenal character". • Phenomenological conceptions of the mind are primarily used as contrast- terms in arguments against metaphysical physicalism. • "Qualia" and similar terms - properly analysed - reveal that they do not, as often claimed, have a "folk-psychological" origin. Rather these terms should be described as highly sophisticated technical terms and should not be confused with non-philosophical notions expressing experiential content. Dualists are obliged to offer us a positive, thus substantive, account of what they mean by "subjective experience" and similar idioms. This is, as I shall point out, a very hard task, mainly due to the strong contrast-mode in which these terms are used. When disconnected from the paradigmatic contrast-context these terms appear more or less out of place. But when faced with a hard-core reductionism the appeal to "phenomenal qualities" seems very appropriate. In my analysis, terms like "what it is like" and "experiential character" are concept that, as such, make perfect sense, but only in a limited context.
