We examine a proposal for dealing with perhaps the chief difficulty facing holistic theories of meaning—meaning instability. The problem is that, given a robust holism, small changes in a representational system are likely to lead to meaning changes throughout the system. Consequently, different individuals are likely never to mean the same thing. Eric Lormand suggests that holists can avoid this problem—and even secure more stability than non-holists—by positing that symbols have multiple meanings. We argue that the proposal doesn't work, (...) however, since multiple meanings are unstable for much the same reason that single meanings are. (shrink)

It is possible to survey humankind and be proud, even to smile, for we accomplish great things. Art and science are two notable worthy human accomplishments. Consonant with art and science are some of the ways we treat each other. Sacrifice and heroism are two admirable human qualities that pervade human interaction. But, as everyone knows, all this goodness is more than balanced by human depravity. Moral corruption infests our being. Why?

This paper examines three cases of the clash between science and philosophy: Zeno’s paradoxes, the Frame Problem, and a recent attempt to experimentally refute skepticism. In all three cases, the relevant science claims to have resolved the purported problem. The sciences, construing the term broadly, are mathematics, artificial intelligence, and psychology. The goal of this paper is to show that none of the three scientific solutions work. The three philosophical problems remain as vibrant as ever in the face of robust (...) scientific attempts to dispel them. The paper concludes by examining some consequences of this persistence.

This essay argues that Plato in the Republic needs an account of why and how the three distinct parts of the soul are parts of one soul, and it draws on the Phaedrus and Gorgias to develop an account of compositional unity that fits what is said in the Republic.

This is a study of Plato's use of the character Socrates to model what philosophy is. The study focuses on the Apology, and finds that philosophy there is the love of wisdom, where wisdom is expertise about how to live, of the sort that only gods can fully have, and where Socrates loves wisdom in three ways, first by honoring wisdom as the gods' possession, testing human claims to it, second by pursuing wisdom, examining himself as he examines others, to (...) achieve a more well justified set of beliefs about how to live, and third by trying to live wisely, insofar as he can, which includes exhorting others to care about living wisely than anything else. The essay also includes some suggestions about how Plato criticizes and revises this model of philosophy outside the Apology. (shrink)

Recently, on the History Channel, artificial intelligence (AI) was singled out, with much wringing of hands, as one of the seven possible causes of the end of human life on Earth. I argue that the wringing of hands is quite inappropriate: the best thing that could happen to humans, and the rest of life of on planet Earth, would be for us to develop intelligent machines and then usher in our own extinction.

In this paper, we outline and critically evaluate Thomas Hofweber’s solution to a semantic puzzle he calls Frege’s Other Puzzle. After sketching the Puzzle and two traditional responses to it—the Substantival Strategy and the Adjectival Strategy—we outline Hofweber’s proposed version of Adjectivalism. We argue that two key components—the syntactic and semantic components—of Hofweber’s analysis both suffer from serious empirical difficulties. Ultimately, this suggests that an altogether different solution to Frege’s Other Puzzle is required.

I offer an interpretation of the puzzle posed by Greenberg’s failure to come to terms with the explosion of postmodernist experimentation in the 1960’s. Greenberg, one of the most influential critics of the immediately preceding period and a strong supporter of New York abstract expressionism and color field painting, is indelibly associated with modernist schools of painting. His short essay, “Modernist Painting”, valorized precisely these movements and was a tour de force catapulting Greenberg into critic superstar status; it is still (...) one of the central documents in debates about modernism. Because Greenberg there makes references to Kant’s aesthetics in identifying the virtues of modernism his account is usually interpreted in terms of the formalism of the period and Kant’s analytic of the beautiful. This offers a reading of Greenberg as a formalist and as identifying modernism with a concern for the formal properties of art, the flatness of the picture frame and the formal relations between the aesthetic properties. Greenberg was also celebrated as having a legendary acuteness of aesthetic appreciation—a critical eye penetrating immediately to a work’s aesthetic depth. (shrink)

The open-domain Frame Problem is the problem of determining what features of an open task environment need to be updated following an action. Here we prove that the open-domain Frame Problem is equivalent to the Halting Problem and is therefore undecidable. We discuss two other open-domain problems closely related to the Frame Problem, the system identification problem and the symbol-grounding problem, and show that they are similarly undecidable. We then reformulate the Frame Problem as a quantum decision problem, and show (...) that it is undecidable by any finite quantum computer. (shrink)

Arguments from consciousness to God’s existence (ACs) contend that physicalism is too problematic to explain the mind’s ultimate source. They add that theism probably better explains this source in terms of God making us in his own image (with conscious, unified, rational minds). But ACs are problematic too. First, physicalism has various competitors beside theism. Russellian monism and dual-aspect theory are examples. Second, all these theories, including theism, are seriously flawed. For example, it’s tied to traditional dualism, which has causal (...) issues (according to Murphy, Churchland, and other physicalists). But we argue that this theistic dualism can be refined to avoid its issues—and the issues in all other theories. So, it probably explains the mind’s origin better than other theories. We rely here on Lowe’s dualism, where the mind’s subject exists immaterially yet spatially, and is a unified, simple entity (unlike neural aggregates with their quite separate parts). This turns the tables on Churchland, Murphy, and other advocates for scientism. -/- . (shrink)

Analogical reminding in humans and machines is a great source for chance discoveries because analogical reminding can produce representational change and thereby produce insights. Here, we present a new kind of representational change associated with analogical reminding called packing. We derived the algorithm in part from human data we have on packing. Here, we explain packing and its role in analogy making, and then present a computer model of packing in a micro-domain. We conclude that packing is likely used in (...) human chance discoveries, and is needed if our machines are to make their own chance discoveries. (shrink)

Patricia Churchland's Touching a Nerve: The Self as Brain is her most recent wide-ranging argument for mind-to-brain reductionism. It's one of the leading anti-dualist works in neurophilosophy. It thus deserves careful attention by anti-reductionists. We survey the main arguments in this book for her thesis that the self is nothing but the brain. These arguments are based largely on the self's dependence upon neural activities as reflected in its various impairments, its unified experiences, and its powers of agency. We show (...) that dualism is quite compatible with this neural dependence. We argue that dualism can not only counter--but also turn the tables on--her arguments. Unlike most other critics, we focus not only on her hard problems but also on her easy problems in explaining consciousness. A new non-Cartesian substance dualism is presented that avoids existing dualist causal issues. It may thus avoid perennial physicalist and dualist problems. -/- . (shrink)

This overview attempts to explain how we can come to an account of Cynicism and what that account should look like. My account suggests that Cynics are identified by living like Diogenes of Sinope, and that Diogenes' way of life is characterized by distinctive twists on three Socratic commitments. The three Socratic commitments are that success in life depends on excellence of the soul; that this excellence and success are a special achievement, requiring hard work; and that this work requires (...) deprecating mainstream values such as wealth, fame, and ordinary political power. Diogenes' construal of success emphasizes freedom and independence, and his construal of excellence emphasizes endurance and self-mastery. On his account, the work required to achieve these is strikingly unintellectual but difficult, and the deprecation of ordinary values is especially extreme. A few interpretive puzzles about Cynicism are tackled along the way, including whether Cynicism really counts as philosophy and whether Cynics are anti-social. (shrink)

One big question in biology is what life is, but another is how life divides into living things. This is the problem of biological individuality. Proposed statements of the problem have been vague and incomplete. And proposed theories of biological individuality are not detailed enough to solve the problem even if they are correct. The root of these troubles is that their authors have not recognized the metaphysical claims presupposed in their statement of the problem. Making these claims explicit will (...) enable us to see better what the problem is and what form a solution to it would need to have. (shrink)

The perennial nature of some of philosophy’s deepest problems is a puzzle. Here, one problem, the realism–anti-realism debate, and one type of explanation for its longevity, are examined. It is argued that realism and anti-realism form a dialetheic pair: While they are in fact each other’s logical opposite, nevertheless, both are true (and both false). First, several reasons why one might think such a thing are presented. These reasons are merely the beginning, however. In the following sections, the dialetheic conclusion (...) is directly argued for by showing how realism and anti-realism satisfy Priest’s “inclosure schema”. In the last section and the conclusion, the conscious mind’s role in creating realism and anti-realism is discussed. This role further supports the conclusion that realism and anti-realism form a dialetheic pair. (shrink)

Consider the following three claims. (i) There are no truths of the form ‘p and ~p’. (ii) No one holds a belief of the form ‘p and ~p’. (iii) No one holds any pairs of beliefs of the form {p, ~p}. Irad Kimhi has recently argued, in effect, that each of these claims holds and holds with metaphysical necessity. Furthermore, he maintains that they are ultimately not distinct claims at all, but the same claim formulated in different ways. I find (...) his argument suggestive, if not entirely transparent. I do think there is at least an important kernel of truth even in (iii), and that (i) ultimately explains what’s right about the other two. Consciousness of an impossibility makes belief in the obtaining of the corresponding state of affairs an impossibility. Interestingly, an appreciation of this fact brings into view a novel conception of inference, according to which it consists in the consciousness of necessity. This essay outlines and defends this position. A central element of the defense is that it reveals how reasoners satisfy what Paul Boghossian calls the Taking Condition and do so without engendering regress. (shrink)

Sometimes analogy researchers talk as if the freshness of an experience of analogy resides solely in seeing that something is like something else -- seeing that the atom is like a solar system, that heat is like flowing water, that paint brushes work like pumps, or that electricity is like a teeming crowd. But analogy is more than this. Analogy isn't just seeing that the atom is like a solar system; rather, it is seeing something new about the atom, an (...) observation enabled by 'looking' at atoms from the perspective of one's understanding of solar systems. The question for analogy researchers then is this: Where does this new knowledge about atoms come from? How can an analogy provide new knowledge and new understanding? (shrink)

PDF with introduction and front and back materials. Abstract: A provocative examination of the consequences of Levinas’s and Adorno’s thought for contemporary ethics and political philosophy. This book unfolds a dialogue between Emmanuel Levinas and Theodor W. Adorno, using their thought to address contemporary environmental and social-political situations. Eric S. Nelson explores the “non-identity thinking” of Adorno and the “ethics of the Other” of Levinas with regard to three areas of concern: the ethical position of nature and “inhuman” material (...) others such as environments and animals; the bonds and tensions between ethics and religion and the formation of the self through the dynamic of violence and liberation expressed in religious discourses; and the problematic uses and limitations of liberal and republican discourses of equality, liberty, tolerance, and their presupposition of the private individual self and autonomous subject. Thinking with and beyond Levinas and Adorno, this work examines the possibility of an anarchic hospitality and solidarity between material others and sensuous embodied life. -/- “This is an extremely impressive, original, and thorough treatment of two key twentieth-century thinkers and their applicability to the most pressing social and political issues of our time.” — Jeffrey A.

PDF includes the introduction. Abstract: In this wide-ranging and authoritative volume, leading scholars engage with the philosophy and writings of Wilhelm Dilthey, a key figure in nineteenth-century thought. Their chapters cover his innovative philosophical strategies and explore how they can be understood in relation to their historical situation, as well as presenting incisive interpretations of Dilthey's arguments, including their development, their content, and their influence on later thought. A key focus is on how Dilthey's work remains relevant to current debates (...) around art and literature, the biographical and autobiographical self, knowledge, language, science, culture, history, society, and psychology and the embodied mind. The volume will be important for researchers in hermeneutics, aesthetics, practical philosophy, and the history of German philosophy, providing a valuable introduction to Dilthey's work as well as detailed critical analysis of its ongoing significance.

An Artificially Intelligent system (an AI) has debatable moral personhood if it is epistemically possible either that the AI is a moral person or that it falls far short of personhood. Debatable moral personhood is a likely outcome of AI development and might arise soon. Debatable AI personhood throws us into a catastrophic moral dilemma: Either treat the systems as moral persons and risk sacrificing real human interests for the sake of entities without interests worth the sacrifice, or do not (...) treat the systems as moral persons and risk perpetrating grievous moral wrongs against them. The moral issues become even more perplexing if we consider cases of possibly conscious AI that are subhuman, superhuman, or highly divergent from us in their morally relevant properties. (shrink)

The purpose of this paper is to present two kinds of analogical representational change, both occurring early in the analogy-making process, and then, using these two kinds of change, to present a model unifying one sort of analogy-making and categorization. The proposed unification rests on three key claims: (1) a certain type of rapid representational abstraction is crucial to making the relevant analogies (this is the first kind of representational change; a computer model is presented that demonstrates this kind of (...) abstraction), (2) rapid abstractions are induced by retrieval across large psychological distances, and (3) both categorizations and analogies supply understandings of perceptual input via construing, which is a proposed type of categorization (this is the second kind of representational change). It is construing that finalizes the unification. (shrink)

Polus admires orators for the tyrannical power they have. However, Socrates argues that orators and tyrants lack power worth having: the ability to satisfy one's wishes or wants (boulēseis). He distinguishes wanting from thinking best, and grants that orators and tyrants do what they think best while denying that they do what they want. His account is often thought to involve two conflicting requirements: wants must be attributable to the wanter from their own perspective (to count as their desires), but (...) wants must also be directed at objects that are genuinely good (in order for failure to satisfy them to matter). We offer an account of wanting as reflective, coherent desire, which allows Socrates to satisfy both desiderata. We then explain why he thinks that orators and tyrants want to act justly, though they do greater injustices than anyone else and so frustrate their own wants more than anyone else. (shrink)

The overwhelming majority of those who theorize about implicit biases posit that these biases are caused by some sort of association. However, what exactly this claim amounts to is rarely specified. In this paper, I distinguish between different understandings of association, and I argue that the crucial senses of association for elucidating implicit bias are the cognitive structure and mental process senses. A hypothesis is subsequently derived: if associations really underpin implicit biases, then implicit biases should be modulated by counterconditioning (...) or extinction but should not be modulated by rational argumentation or logical interventions. This hypothesis is false; implicit biases are not predicated on any associative structures or associative processes but instead arise because of unconscious propositionally structured beliefs. I conclude by discussing how the case study of implicit bias illuminates problems with popular dual-process models of cognitive architecture. (shrink)

I find it interesting that AI researchers don't use concepts very often in their theorizing. No doubt they feel no pressure to. This is because most AI researchers do use representations which allow a system to chunk up its environment, and basically all we know about concepts is that they are representations which allow a system to chunk up its environment.

Plato argues that four political arts—politics, kingship, slaveholding, and household-management—are the same. His argument, which prompted Aristotle’s reply in Politics I, has been universally panned. The problem is that the argument clearly identifies household-management with slaveholding, and household-management with politics, but does not fully identify kingship with any of the others. I consider and reject three ways of saving the argument, and argue for a fourth. On my view, Plato assumes that politics is identical with kingship, just as he does (...) elsewhere, but he begs no questions because the point of his argument is to identify the public arts of politics and kingship with the private arts of household-management and slaveholding. He does this successfully by answering three reasons why one might distinguish the private from the public arts. His argument leaves room for Aristotle to propose other reasons. One of them—involving differences among men and women and slaves—is unfortunate, but another is more promising. The Aristotelian can assume that political expertise is a matter of know-how gathered by experience of the particular actions which differ in the public and private arts. But Plato might well be right to reject this, and to insist that the essential difference between the expert and non-expert—the dividing line between good and bad rule—is not in experience but in their grasp of their goals.

Mostly philosophers cause trouble. I know because on alternate Thursdays I am one -- and I live in a philosophy department where I watch all of them cause trouble.

And, we know where they tend to cause it: in knowledge representation and the semantics of data structures. This essay is about a recent case (...) of this sort of thing. One of the take-home messages will be that AI ought to redouble its efforts t o understand concepts. (shrink)

In mid-May of 2001, I attended a fascinating workshop at Cold Spring Harbor Labs. The conference was held at the lab's Banbury Center, an elegant mansion and its beautiful surrounding estate, located on Banbury Lane, in the outskirts of Lloyd Harbor, overlooking the north shore of Long Island in New York. The estate was formerly owned by Charles Sammis Robertson. In 1976, Robertson donated his estate, and an endowment for its upkeep, to the Lab. The donation included the Robertson's mansion, (...) now called Robertson House, and a large, seven-car garage that would become the actual conference center. The Center was opened on Sunday, June 14, 1977, by Francis Crick who gave a talk entitled "How Scientists Work." For us, Banbury was an idyllic location with great food where we could talk about the most difficult problem in all o f science: what is the nature and cause of consciousness? (shrink)

An analysis of a valenced corpus of English words revealed that words that rhyme with slurs are rated more poorly than their synonyms. What at first might seem like a bizarre coincidence turns out to be a robust feature of slurs, one arising from their phonetic structure. We report novel data on phonaesthetic preferences, showing that a particular class of phonemes are both particularly disliked, and overrepresented in slurs. We argue that phonaesthetic associations have been an overlooked source of some (...) of the more peculiar, arational aspects of slurs. We conclude by drawing broader morals about the evolution of the lexicon. (shrink)

“What is the structure of thought?” is as central a question as any in cognitive science. A classic answer to this question has appealed to a Language of Thought (LoT). We point to emerging research from disparate branches of the field that supports the LoT hypothesis, but also uncovers diversity in LoTs across cognitive systems, stages of development, and species. Our letter formulates open research questions for cognitive science concerning the varieties of rules and representations that underwrite various LoT-based systems (...) and how these variations can help researchers taxonomize cognitive systems.

According to one interpretation of Aristotle’s famous thesis, to say that action is the conclusion of practical reasoning is to say that action is itself a judgment about what to do. A central motivation for the thesis is that it suggests a path for understanding the non-observational character of practical knowledge. If actions are judgments, then whatever explains an agent’s knowledge of the relevant judgment can explain her knowledge of the action. I call the approach to action that accepts Aristotle’s (...) thesis so understood Normativism. There are many reasons to doubt Normativism. My aim in this paper is to defend Normativism from a pair of arguments that purport to show that a normative judgment could not constitute an event in material reality and also the knowledge of such a happening. Both highlight a putative mismatch between the natures of, on the one hand, an agent’s knowledge of her normative judgment and, on the other, her knowledge of her own action. According to these objections, knowledge of action includes (a) perceptual knowledge and (b) knowledge of what one has already done. But knowledge of a normative judgment includes neither. Hence knowledge of action cannot simply be knowledge of a normative judgment. (shrink)

The dominant Greek and Roman ideology held that the best human life required engaging in politics, on the grounds that the human good is shared, not private, and that the activities central to this shared good are those of traditional politics. This chapter surveys three ways in which philosophers challenged this ideology, defended a withdrawal from or transformation of traditional politics, and thus rethought what politics could be. Plato and Aristotle accept the ideology's two central commitments but insist that a (...) few exceptional human beings could transcend the good of human activities. Epicurus argues that the human good is private, not shared. Socrates and some of his followers, including especially the Stoics, argue that the activities central to the shared human good are not those of traditional politics. (shrink)

A quick introduction to category theory and topos theory, axiomatically. These notes are adapted from Prof. Pettigrew’s notes.

Plato's dialogues use several terms for the concept of well-being, which concept plays a central ethical role as the ultimate goal for action and a central political role as the proper aim for states. But the dialogues also reveal sharp debate about what human well-being is. I argue that they endorse a Socratic conception of well-being as virtuous activity, by considering and rejecting several alternatives, including an ordinary conception that lists a variety of goods, a Protagorean conception that identifies one's (...) well-being with what appears one to be one's well-being, and hedonistic conceptions.

How do you know what you want? Philosophers have lately developed sophisticated accounts of the practical and doxastic knowledge that are rooted in the point of view of the subject. Our ability to just say what we are doing or what we believe—that is, to say so authoritatively, but not on the basis of observation or evidence—is an aspect of our ability to reason about the good and the true. However, no analogous route to orectic self-knowledge is feasible. Knowledge of (...) desire is distinctive in being a matter of our affective response to imagined prospects. An examination of this idea yields the following thesis: I know what I want just in case the object pursued in anticipation of a certain pleasure actually yields the anticipated pleasure. (shrink)

This essay is about the significance of communication and the ineffable for the question of hermeneutics. I argue that Friedrich Schleiermacher’s hermeneutics needs to be interpreted in the context of his early religious thought and that the play between communication and what resists and withdraws from communication provides an alternative conception of the tasks of hermeneutics. Hermeneutics is not only constituted by what is said and what is left unsaid but, further, by that which is unsayable. Finally, the relation and (...) non-relation of meaning and the ineffable is articulated in its ethical import by exploring the questions of alterity, singularity and responsiveness. (shrink)

True contradictions are taken increasingly seriously by philosophers and logicians. Yet, the belief that contradictions are always false remains deeply intuitive. This paper confronts this belief head-on by explaining in detail how one specific contradiction is true. The contradiction in question derives from Priest's reworking of Berkeley's argument for idealism. However, technical aspects of the explanation offered here differ considerably from Priest's derivation. The explanation uses novel formal and epistemological tools to guide the reader through a valid argument with, not (...) just true, but eminently acceptable premises, to an admittedly unusual conclusion: a true contradiction. The novel formal and epistemological tools concern points of view and changes in points of view. The result is an understanding of why the contradiction is true. (shrink)

It is shown that the Fodor's interpretation of the frame problem is the central indication that his version of the Modularity Thesis is incompatible with computationalism. Since computationalism is far more plausible than this thesis, the latter should be rejected.

I argue that central to Aristotle’s account of vice is a distinction between two varieties of vicious person: those for whom character change is possible (the curable), and those for whom it is not (the incurable). Recognizing this distinction and drawing out the ideas which ground it shows why Aristotle’s discussions of vice in EN vii and ix 4 are not inconsistent.

We propose four policies of ethical design of human-grade Artificial Intelligence. Two of our policies are precautionary. Given substantial uncertainty both about ethical theory and about the conditions under which AI would have conscious experiences, we should be cautious in our handling of cases where different moral theories or different theories of consciousness would produce very different ethical recommendations. Two of our policies concern respect and freedom. If we design AI that deserves moral consideration equivalent to that of human beings, (...) that AI should be designed with self-respect and with the freedom to explore values other than those we might impose. We are especially concerned about the temptation to create human-grade AI pre-installed with the desire to cheerfully sacrifice itself for its creators’ benefit. (shrink)

Based on three recently published books on climate justice, this article reviews the field of climate ethics in light of developments of international climate politics. The central problem addressed is how idealised normative theories can be relevant to the political process of negotiating a just distribution of the costs and benefits of mitigating climate change. I distinguish three possible responses, that is, three kinds of non-ideal theories of climate justice: focused on (1) the injustice of some agents not doing their (...) part; (2) the policy process and aiming to be realistic; and (3) grievances related to the transition to a clean-energy economy. The methodological discussion underpinning each response is innovative and should be of interest more generally, even though it is still underdeveloped. The practical upshot, however, is unclear: even non-ideal climate justice may be too disconnected from the fast-moving and messy climate circus. (shrink)

Nick Bostrom’s Simulation Argument (SA) has many intriguing theological implications. We work out some of them here. We show how the SA can be used to develop novel versions of the Cosmological and Design Arguments. We then develop some of the affinities between Bostrom's naturalistic theogony and more traditional theological topics. We look at the resurrection of the body and at theodicy. We conclude with some reflections on the relations between the SA and Neoplatonism (friendly) and between the SA and (...) theism (less friendly). (shrink)

People cannot contemplate a proposition without believing that proposition. A model of belief fixation is sketched and used to explain hitherto disparate, recalcitrant, and somewhat mysterious psychological phenomena and philosophical paradoxes. Toward this end I also contend that our intuitive understanding of the workings of introspection is mistaken. In particular, I argue that propositional attitudes are beyond the grasp of our introspective capacities. We learn about our beliefs from observing our behavior, not from introspecting our stock beliefs. -/- The model (...) of belief fixation offered in the dissertation poses a novel dilemma for theories of rationality. One might have thought that the ability to contemplate ideas while withholding assent is a necessary condition on rationality. In short, it seems that rational creatures shouldn‘t just form their beliefs based on whatever they happen to think. However, it seems that we are creatures that automatically and reflexively form our beliefs based on whatever propositions we happen to consider. Thus, either the rational requirement that states that we must have evidence for our beliefs must be jettisoned or we must accept the conclusion that we are necessarily irrational. (shrink)
