Color Incompatibility and Length Incompatibility

Time & Place: Wed 26 Nov 2008 at 16:40 in G160

It would seem that an object cannot be both red and green all over at the same time. That the entire surface of an object cannot be uniformly colored with more than one color simultaneously is known as the color incompatibility phenomenon, and the problem of explaining why this is so is known as the color incompatibility problem. The majority of philosophers who have dealt with the issue (including Wittgenstein who gave a lot of thought to the "logic of colors") have argued that color incompatibility is a necessary, and not merely accidental, truth. The "color incompatibilists," as I call them, differed on the nature of that necessity, some arguing that it is an analytical necessity deriving from the meanings of color terms, others arguing that it is an example of metaphysical necessity, still others contending that color incompatibility is an example of the synthetic a priori. I join the minority of philosophers who think that the color incompatibility claim is just a contingent truth, if truth indeed. I offer a speculative evolutionary account of why we have the color incompatibility phenomenon. A, to my mind, more intriguing question -- which is not asked very often, if at all -- is whether an object can have more than one length (or volume, or mass, etc.) at the same time. This analogous problem about lengths, I submit, is a more puzzling one. It leads us to the question of whether it is possible to have a consistent geometry which assigns more than one shortest distance between a pair of distinct points.

Constructivism, Contractarianism and Basic Obligations: Kant and Gauthier

Time & Place: Wed 12 Nov 2008 at 17:40 in G160

Gauthier's contractarianism begins with an idea of a rational deliberator but "finds no basis for postulating a moral need for the justification of one's actions to others. The role of agreement is to address each person's demand that the constraints of society be justified to him, not a concern that he justify himself to his fellows" (Gauthier 1997, 134–5). He contrasts his view with Scanlon's contractualism, according to which agreement with others is the core of morality and each agent has the burden of justifying his or her actions to others. Both of their views count as 'constructivist' because they reject moral realism and hold that normativity is a function of what we do, either individually or collectively. Kant's Rechtslehre is neutral regarding moral realism and yet constructivist about moral norms. However, the relevant acts basic to Gauthier's and Scanlon's views concern voluntary agreements we make. Using agreement to establish basic norms faces some serious difficulties. Kant's Rechtslehre avoids these problems by showing how basic social norms can be identified and justified independently of voluntary agreement. Moreover, it does so in a way that shows that an individual's justification of his or her acts to others and the justification of the acts of others to any individual are inseparable aspects of one and the same justificatory reasons in which voluntary agreement plays no role.

Thinking the Abyss from Plotinus to Nietzsche

Time & Place: Wed 14 May 2008 at 9:40 in A214

Western philosophy has, according to most accounts, depended on a Platonic ontology that identifies intelligibility and reason (Logos) as the touchstone for that which constitutes the truly real. In this talk, I will explore the foundations and legacy of a tradition of thought, stemming from Plato, that posits a singularly transcendent source beyond the intelligible, and hence "beyond being" (epekeina tes ousias). From this Neoplatonic tradition, beginning with Plotinus in the 3rd century, we may trace the uneasy intersections of philosophical and religious thought not only in the work of Christian, Muslim, and Jewish mystics, but in perhaps more unlikely venues: namely Kant, Schelling, and Nietzsche, insofar as they are thinkers of the unthinkable abyss that lies beyond logos, reason, and (Cartesian) subjectivity.

The Enormous Danger

Time & Place: Thu 24 Apr 2008 at 17:40 in G160

In the midst of the well known discussion of aspect-seeing in Part II of the Investigations, Wittgenstein warns us of "the enormous danger of wanting to make fine distinctions." (PI II page 200) This warning caught my attention because of the apparent lack of fit between its urgent tone, an enormous danger, and the object of this urgent fear, making fine distinctions. What could be the life threatening implications of making fine distinctions? Are we to be murdered with jewelers' tools? I argue that what Wittgenstein fears is that he will not be able to bring his philosophical anxieties peace, and so he willfully turns his back on experience and forces his investigations to end. If he had welcomed these experiences, he would have found himself, not rejecting, but joining forces with a Bergsonian account of the immediate data of consciousness, which promises not peace, but sensual delight.

Rigid General Terms and Essential Predicates

Time & Place: Fri 21 Mar 2008 at 16:40 in A214

What does it mean for a general term to be rigid? It is argued by some that if we take general terms to designate their extensions, then almost no empirical general term will turn out to be rigid; and if we take them to designate some abstract entity, such as a kind, then it turns out that almost all general terms will be rigid. Various authors who pursue this line of reasoning have attempted to capture Kripke's intent by defining a rigid general term as one that applies to the objects in its extension essentially. I argue that this account is significantly mistaken for various reasons: it conflates a metaphysical notion (essentialism) with a semantic one (rigidity); it fails to countenance the fact that any term can be introduced into a language by stipulating that it be a rigid designator; it limits the extension of rigid terms so much that terms such as meter, rectangle, truth, etc. do not turn out to be rigid, when they obviously are; and it wrongly concentrates on the predicative use of a general term in applying a certain test offered by Kripke to determine whether a term is rigid.

Geometrical Interpretations (or Analysis) of Knowledge

Time & Place: Tue 15 Jan 2008 at 14:40 in G160

Since 1930s the geometric and topological interpretations of modal logics were known and studied upon, initiated by prominent mathematicians A. Tarski and J. C. C. McKinsey. In this talk, we will briefly mention the formal epistemological tools to analyze the knowledge referring to Hintikka and Moss & Parikh. Then, I will recall a topological analysis of knowledge. In the last part of the talk, I will mention the notion of common knowledge introduced by D. Lewis. Finally, I will conclude with some geometrical interpretations of common knowledge.


Jean Salem (Directeur du Centre d'Histoire des Systčmes de Pensée Moderne, Paris I Sorbonne)

Reconstructing Democritus

Time & Place: Mon 17 Dec 2007 at 17:40 in G160

Jean Salem will present an explanatory synopsis of his book Démocrite: Grains de poussičre dans un rayon de soleil, which was published in Paris by Vrin in 1996 (416 pp - 2nd enlarged edition, 2002, 432 pp).

He has analysed the general principles of Democritean atomism (Ch. 1), the cosmogony meriting a chapter to itself (2). The treatment of the theory of knowledge (3), followed by that of the theory of the soul, or psychology (4), will bring the audience to reflect on these very special constructions, which have something of the nature of living beings. After that J. Salem will attempt to show how Democritean medicine and embryology inspired Hippocratism and elicited Aristole's marked reaction (5). The numerous textual fragments collected by Diels and Luria deal very widely with the specifically human domain, sometimes with markedly modern perspectives, and anthropology (6) and ethics (7) are treated in two separate chapters. Finally, Jean Salem will take seriously the legendary Democritean hilarity, the attitude supposedly taken by the sage towards the spectacle of the universal folly of mortals (8).

Scepticism in Pyrrhonism, Hume and Nietzsche

Time & Place: Thu 13 Dec 2007 at 17:40 in G160

The aim of this presentation is to explain the relationship between the skepticism of Pyrrhonism, Hume and Nietzsche; to show the significant influence of the Pyrrhonian arguments on Hume and Nietzsche, which is essential for understanding the philosophies of the two.

Grammars, Programs and the Chinese Room Argument of Searle

Time & Place: Thu 6 Dec 2007 at 17:40 in G160

The Chinese Room debate took place between Searle, philosophers, psychologists and AI researchers, with almost no argument from linguistics. I offer one in this paper from philosophy of linguistics, as follows.

Searle's Chinese symbol correspondence program in the room cannot be of infinite size, therefore the correspondences cannot be phrase-to-phrase matching, for we know that there are infinitely many Chinese expressions. Hence the program must contain finitely characterizable symbols and their program-internal abstractions, i.e., a generative grammar of Chinese.

We must assume that the program contains a generative grammar because we can "suppose also that the programmers get so good at writing the programs that from the external point of view [..] my answers to the questions are indistinguishable from those of native Chinese speakers." (Searle 1980, my emphasis).

I claim that the experimental setup is inconsistent because of the forced assumption of having a generative grammar, and not being able to use it for semantic interpretation; all generative grammars are interpretable because their product, a structural description, is there solely to provide a full array of phonetic, semantic and syntactic interpretation.

In linguistic sense, Searle's program is not doing computation at all, because computation is what links the expression and the meaning at the interfaces to perceptual and conceptual systems of cognition. It is not computation in computing science sense either, for computing there too is to link programs (the form) with executable code (the meaning).

There is already some progress in the way of breaking the "semantic divide." Zettlemoyer and Collins (2005) report an experiment in statistical learning of generative grammars, in which the training data (for the machine) are sound-meaning pairs, and in which syntax is a hidden variable, that is, there is no external access to the internal states of a program such as Searle's. Therefore, the input to the room must be sound-meaning pairs in order for computation to take place.

In summary, (i) Searle's Chinese Room is linguistically inadequate, and (ii) it can be made consistent with bona fide computation, in which case the unduly pessimistic belief that a computational system cannot be made to face the same conditions for understanding as humans is not warranted.

How to Settle Human Rights Responsibilities: The Problem of Non-State Actors

Time & Place: Fri 2 Nov 2007 at 17:40 in G160

International Human Rights Law is clear in holding only states or state-like entities responsible for human rights abuses, yet activists and philosophers alike do not see any rational basis for this restriction in responsibility. Multi-national corporations, individuals and a whole array of other 'non-state actors' are capable of harming vital human interests just as much as states, so why single-out the latter as human rights-responsible agents? In this paper I distinguish two ways of looking at human rights responsibility. One is simply in terms of the outcomes that are deemed desirable to avoid (or secure), and the other is in terms of the relationships one sees these moral standards as governing. I argue that the peculiar form of responsibility and responsiveness (the way of 'holding to account') inherent to human rights principles is directed at establishing a particular type of relationship: one in which individuals are empowered in the face of a very special form of communal power. Other kinds of relationship and potential transgression are more appropriately governed by different kinds of moral principles, such as those relating to criminality. The outcomes view fails to incorporate this insight and for that reason fails to see the distinct role played by human rights standards in our moral reasoning: they are precisely valuable because they provide a way to judge the relationship of individuals to the peculiar kind of power exercised by the state.

Sex and Gender in Judith Butler

Time & Place: Fri 20 Apr 2007 at 15:40 in G160

"Anatomy/biology is destiny" may be the most taken for granted formula supposedly defining the relationship between sex and gender. This formula, coming from certain premises of psychology, medicine, juridical systems, and religion gave rise to criticism on the part of feminist thinkers. According to the "anatomy/biology is destiny" formula, one's "natural" and "innate" sex is what determines one's gender. Starting with Simone de Beauvoir, many feminist thinkers gave arguments against this presupposition. This paper concentrates on how Judith Butler defines the relationship between sex and gender but does not claim to cover all the premises and thoughts of Butler on this topic. The purpose here is to explain the reasons behind certain claims that make it possible for Butler to assert that "sex is always already gender" as well as to open up a space that will allow for further reflection on the relationship between sex and gender.

A Fabulous Story: How Euclid Came up with the Idea of an Axiomatic System

Time & Place: Tue 5 Dec 2006 at 15:40 in G160

I have a simple and modest aim in this talk: to attempt to demystify the "genesis" of Euclid's axiomatics. For example, Kolmogorov (1975), van der Waerden (1961), Heath (1956), Neugebauer (1957), von Fritz (1955), and Szabo (1978) give accounts of the origins of Euclid's axiomatics. However, they all seem to share one common view: although Greeks inherited the mathematical practice of the previous civilizations, there are basically two fundamentally distinct periods in the development of mathematics, specifically geometry, starting from the Babylonian and Egyptian mathematics to the Greek mathematics. It seems to be a relatively short period of time, and yet it is the most perplexing and important period in the history of mathematics; for geometry had been conducted and developed in an empirical/inductive manner before the Greeks, but with the Greeks it entered "upon the sure path of science", and became a deductive/axiomatic science.

My story can be summarized as follows: it is true that acclimatization is certainly a Greek achievement. However, it came about as a natural result of carrying out the mathematical practice at philosophical schools, not that of an intention of doing mathematics in a radically different way. It was a result of doing and teaching geometry at these schools. So on my account it seems to be an unintended consequence of conducting geometrical activity then, and the "axiomatic turn" is in considerable measure pedagogical.

Who Guards the Guardians? The Ethics of the Ownership of Cultural Artifacts

Time & Place: Tue 28 Nov 2006 at 10:40 in G160

The issue of who owns what has recently become a hotly contested issue when it comes to cultural artifacts. Many museums are returning objects that they have complete legal rights over. Ought they to feel guilty about owning what amounts to the cultural heritage of other countries and cultures or should nations unable to look adequately after heritage be dispossessed of it? An attempt will be made to sort out some of the moral and political issues that exist on this topic and work out an adequate moral response to a range of relevant concerns.

Kierkegaard and Moral Psychology

Time & Place: Wed 20 Apr 2005 at 16:40 in FA113

The aim of the paper is to construct Kierkegaard's contributions to questions of free will, and motivations to goodness or evil. For Kierkegaard, there is free will, as consciousness exists as an autonomous power of self-reflection and decision-making. That leaves the question of what leads us to good or evil acts and principles. There is a potential conflict here, which was very much an issue for Kant. The conflict is between the autonomy of the self, which makes the self a moral agent, and morality as what is externally legislated. The Concept of Anxiety is centrally concerned with this issue particularly as it arises with regard to evil. Kant himself was concerned with how the autonomous rational self can will evil for its own sake (in Religion within the Boundaries). Kierkegaard's approach is to emphasise that free will itself creates its own constraints. The apparent approach of The Concept of Anxiety is to deal with a theological question of how there can be an evil will in humans, but essentially the book is concerned with the moral consequences of free will. Morality means there is agency according to Kierkegaard and it also means following universal rules. Free will gives rise to anxiety because it is where agency faces with the infinity of its choices (both in their quantity and the scope of certain choices). This picture of consciousness owes a great deal to Fichte. Faced with the infinity of its own possibilities free will lacks a basis for choice, for seeing where it is itself. That difficulty in distinguishing between choices, some infinite, or universal, moral choices is what creates anxiety and melancholy. In that state we may choose evil, and in that stage there is something intrinsically evil, for it is a state of mind where no choice is ethically significant, and subjectivity only seeks to enjoy the variety of subjective moments. In Either/Or Kierkegaard suggests stages of the aesthetic-subjective, the moral-ethical and the absolute-religious. Kierkegaard after McIntyre has performed a great service by drawing attention to the ethics in Either/Or, but suffers from treating the stage of anxiety, or melancholy, as superseded by the ethical. The ethical can only have a place in Kierkegaard if it connects with anxiety, because the ethical in itself is universal laws abstracted from the self. Ethics must rest on the absolute, that is a subjectivity which recognises an absolute within itself which integrates all the passing moments of aesthetic melancholia. Kierkegaard claims that ethics rests on a personality, which is necessarily struggling to integrate itself.

Proxy Consent and Counterfactuals

Time & Place: Tue 8 Mar 2005 at 13:40 in EA409

When patients are in vegetative states and their lives are maintained by medical devices, their surrogates might offer proxy consents on their behalf in order to terminate the use of the devices. The so-called 'substituted judgment thesis' has been adopted by the courts regularly in order to determine the validity of such proxy consents. The thesis purports to evaluate proxy consents by appealing to putative counterfactual truths about what the patients would choose, were they to be competent. The aim of this paper is to reveal a significant limitation of the thesis, which has hitherto been recognized only vaguely and intuitively. By appealing to the metaphysics of counterfactuals I explain how the thesis fails to determine the validity of proxy consents in a number of actual cases.

The Map and the Treasure: Reflections on Meno's Paradox

Time & Place: Fri 17 Dec 2004 at 15:40 in FA113

Meno's Paradox reveals important issues with respect to philosophical inquiry in particular, and human curiosity in general. It should not be dismissed as a verbal quibble, as some have suggested, and it is not at all clear that Plato had a satisfactory solution to it. As has been noted by Plato scholars there are two issues raised by Meno: how is it possible to inquire into something? (The Paradox of Inquiry); how is it possible to discover the right answer to an inquiry? (The Paradox of Discovery). The Theory of Recollection does not provide us with an answer to the Paradox of Inquiry, even if we countenance immortal and omniscient souls, and it is not clear whether Socrates thought it did. There are the two standard approaches that have been suggested in the literature to resolve the paradoxes. The first has it that having true beliefs (but no knowledge) about something is sufficient to inquire into it (which was presumably Socrates' own solution to the first paradox), whereas the second approach finds fault in the underlying assumption that knowledge is an all-or-nothing affair. I will argue that neither account is fully satisfactory. A more substantial solution to the Paradox of Inquiry requires us to investigate how it is possible for one to represent an object in his mind without being acquainted with that object. Such a form of representation, I shall argue, is made possible by a certain type of concept formation that I shall call "inostensible". It is through the use of an inostensible concept that one is able to inquire into something (empirical or a priori) even in cases when that person has no de re beliefs (let alone knowledge) about that thing. In the light of this I will try to show how the Paradox of Inquiry can be resolved in the case of Platonic questions such as "what is virtue?" Such a solution does not seem to be available to Plato, for it is quite doubtful that Plato distinguished between concept and object, let alone having the notion of an inostensible concept. Inostensible concept formation will also provide a resolution to the Paradox of Discovery for empirical inquiries, though I shall argue that for the kind of philosophical issues that Plato raises, the Paradox of Discovery opens up a deeper issue with respect to the possibility of metaphysical knowledge, which is perhaps what led Plato to endorse the Theory of Recollection.

Shadows and Other Things of No Substance

Time & Place: Fri 15 Oct 2004 at 13:40 in FA113

In this day and age we should know everything there is to know about shadows and ordinary holes, right? Well, not if you look at the different views among philosophers concerning what shadows and holes are, and how or whether they move. For starters, is the circular hole in a donut part of the donut? When the donut rotates does its hole also rotate? What is a shadow made out of? Does the shadow cast by a spinning disc spin too? How about a silhouette? I present my own theory of the structure of holes and of shadows, and the nature of their motion. I reply to Roy Sorensen’s criticisms in a forthcoming paper of my views, and solve some puzzles he poses concerning shadows and their motion.

Hippias of Elis

Time & Place: Mon 27 Sep 2004 at 14:40 in EB309

Hippias of Elis cut an elegant figure as he strolled through the crowds at Olympia, dressed entirely in garments and accessories he had, himself, made. But there is more to Hippias than the man Plato portrays as vain in Hippias Minor. Hippias was not only the exemplar of self-sufficiency but ranks among the most talented and versatile of the sophists. He was perhaps the earliest chronologist, a prolific writer, and lectured on poetry, grammar, history, politics, mythology, and archaeology. It has been said that Hippias's only contribution to mathematics was the discovery of the quadratrix, but what a discovery that was! Hippias's discovery of the quadratrix was a remarkable achievement. In addition, he held a view on social law, relating to positive law and convention. Mention will be made of Plato's portrayal of Hippias. It will be seen that Hippias was more than an extremely rich and successful sophist, but that his work warrants his inclusion amongst the philosophers.

Three Basic Ontological Relations Concerning the Physical Realm

Time & Place: Mon 17 May 2004 at 14:40 in EA409

The purpose of this paper is to establish a classification of the main ontological categories based on the predication, subsumption, and inherence relation. The classification is inspired by Aristotle's fourfold division of things into objects (primary substances), object kinds (secondary substances), attributes, and attribute kinds. It is argued that first, properties and relations are respectively meanings of monadic and polyadic predicate expressions, and second, (determinate) attributes are recurrent abstract particulars so that they are neither monadic nor polyadic. It follows that attributes constitute a category quite different from that of properties and relations. On the other hand, both object kinds and attribute kinds are considered to be non-semantic universals in contradistinction to properties and relations that are semantic.

Philosophy of Literary Form: Lukács and Benjamin

Time & Place: Thu 1 Apr 2004 at 17:40 in A130

This paper is work in progress for a book with the provisional title of 'Philosophy of Literary Judgement', which looks at aesthetic philosophy, and philosophy and literature, since Vico and Kant with regard to developing a framework for reading Joyce and Beckett, and considering what they have to tell us about aesthetic and literary philosophy.

In Lukács and Benjamin themes established by Kant and Vico, then developed in German Idealism, the Jena Romantic Ironists, Kierkegaard and Nietzsche, are continued and in some respects reach a culmination. For Lukács and Benjamin literary form still expresses historical categories and the growth of consciousness, but also in ways which suggest a dissolve of the original synthesis, and maybe gives some clues to the rise of the kind of literature we see in Joyce and Beckett. Indeed there is an evolution in the thought of Lukács and Benjamin, which suggests an awareness of this dissolve. Lukács adopted Marxism, establishing an influential Marxist social and historical philosophy and Benjamin came to emphasise Marxism more over time, together with interests in mass culture. The work considered here, is still clearly German Idealist in emphasis. That is Lukács Theory of the Novel and Benjamin's Origin of German Tragic Drama. That their greatest work came early may say something about the problems in their later evolution, though they did of course continue to produce remarkable work. An incapacity to accept the kind of literature written by Joyce and Beckett is an issue for Lukács already in Theory of the Novel, and continues to be in the Marxist work which provides a moral-historical condemnation of this kind of 'alienation'. Benjamin emphasised Kafka and Proust positively and was closer to literary Modernism than Lukács, nevertheless his reading of Proust in apocalyptic-Marxist terms and of Kafka in Judaic allegorical terms may suggest some perplexity about how to deal with this work in every dimension. We might get a better grasp of Beckett and Joyce with reference to the earlier work of both. Benjamin's discussion of the Baroque and of tragic-drama and Lukács discussion of reflection in the novel, are highly suggestive and should lead us to think about how we can categorise modernism, when it seems anticipated by Romanticism in the novel and a reading of the Baroque from the point of view of Romantic aesthetics. In both cases a dissolve of given literary structure is important. In Lukács, there is a historical progress clearly inspired by Hegel, according to which the Homeric epic represents an ideal In which the individual feels at home in the world and does not even contemplate alienation from the world. The novel is partly seen in terms of a Hegelian critique of Kant, in a sense that the novel as a form is determined by the universality of abstract law alien to particularity. The novel is examined in a way which Hegel did not, and could not given its development since his time, according to the suggestion that increasingly only exist as a law breaker and outsider, and that the novel can increasingly only find unity of a non-organic kind through pure time and so on. In Benjamin, the struggle of the hero in Ancient Tragedy, and the unity of its structure, is contrasted with the passivity of the hero of the 'mourning play' in a modern world without natural justice and in which justice has become abstract divine law. A contrast itself rooted in Hegel. The shift between Tragedy and Tragic Drama parallels that in Lukács from epic to novel, but the epochs considered and other terms in the opposition, differ in exposition and need to be explored.
