The Uniqueness Thesis (U), according to Richard Feldman and Roger White, says that for a given set of evidence E and a proposition P, only one doxastic attitude about P is rational given E. Luis Rosa has recently provided two counterexamples against U which are supposed to show that even if there is a sense in which choosing between two doxastic attitudes is arbitrary, both options are equally and maximally rational. Both counterexamples work by exploiting the idea that (...) ‘ought implies can’ and trying to spell out situations in which some inferences are beyond the capabilities of some reasoners. I argue that on a descriptive account of doxastic rationality, questions of whether ‘epistemic ought implies can’ can be bracketed and that at least one of the inferential moves that Rosa describes in his cases is irrational. I further argue that a descriptive account of doxastic rationality is the appropriate notion of rationality that is to be considered when evaluating U. If my argument for a descriptive account of rationality is successful, then we have reason to revise our use of the term rationality to fit this descriptive understanding. (shrink)

In this paper, I offer two counterexamples to the so-called ‘Uniqueness Thesis.’ As one of these examples rely on the thesis that it is possible for a justified belief to be based on an inconsistent body of evidence, I also offer reasons for this further thesis. On the assumption that doxastic justification entails propositional justification, the counterexamples seem to work.

This dissertation proposes and defends a hybrid view I call Hybrid Impermissivism, which combines the following two theses: Moderate Uniqueness and Credal Permissivism. Moderate Uniqueness says that no evidence could justify both believing a proposition and its negation. However, on Moderate Uniqueness, evidence could justify both believing and suspending judgement on a proposition (hence the adjective “Moderate”). And Credal Permissivism says that more than one credal attitude could be justified on the evidence. Hybrid Impermissisim is developed into (...) a precise theory by using normative bridge principles on how rational belief and credence ought to interact. My overall conclusion is that Hybrid Impermissivism is a coherent, plausible, and conciliatory position and provides a correct characterisation of the requirements of evidence on doxastic attitudes .

I reinforce my defense of permissivism about the rationality of doxastic attitudes on the face of a certain body of evidence against criticism published in this journal by Anantharaman. After making some conceptual clarifications, I manage to show that at least one of my original arguments pro-permissivism is left unscathed by Anantharaman's points.

In recent years, permissivism—the claim that a body of evidence can rationalize more than one response—has enjoyed somewhat of a revival. But it is once again being threatened, this time by a host of new and interesting arguments that, at their core, are challenging the permissivist to explain why rationality matters. A version of the challenge that I am especially interested in is this: if permissivism is true, why should we expect the rational credences to be more accurate than the (...) irrational ones? My aim is to turn this challenge on its head and argue that, actually, those who deny permissivism will have a harder time responding to such a challenge than those who accept it. (shrink)

This paper discusses the uniqueness thesis, a core thesis in the epistemology of disagreement. After presenting uniqueness and clarifying relevant terms, a novel counterexample to the thesis will be introduced. This counterexample involves logical disagreement. Several objections to the counterexample are then considered, and it is argued that the best responses to the counterexample all undermine the initial motivation for uniqueness.

Pascal Engel (2008) has insisted that a number of notable strategies for rejecting the knowledge norm of assertion are put forward on the basis of the wrong kinds of reasons. A central aim of this paper will be to establish the contrast point: I argue that one very familiar strategy for defending the knowledge norm of assertion—viz., that it is claimed to do better in various respects than its competitors (e.g. the justification and the truth norms)— relies on a presupposition (...) that is shown to be ultimately under motivated. That presupposition is the uniqueness thesis—that there is a unique epistemic rule for assertion, and that such a rule will govern assertions uniformly. In particular, the strategy I shall take here will be to challenge the sufficiency leg of the knowledge norm in a way that at the same time counts against Williamson’s (2000) own rationale for the uniqueness thesis. However, rather than to challenge the sufficiency leg of the knowledge norm via the familiar style of ‘expert opinion’ and, more generally, ‘second-hand knowledge’ cases (e.g. Lackey (2008)), a strategy that has recently been called into question by Benton (2014), I’ll instead advance a very different line of argument against the sufficiency thesis, one which turns on a phenomenon I call epistemic hypocrisy. (shrink)

In this paper I argue for a version of the Total Evidence view according to which the rational response to disagreement depends upon one's total evidence. I argue that perceptual evidence of a certain kind is significantly weightier than many other types of evidence, including testimonial. Furthermore, what is generally called "The Uniqueness Thesis" is actually a conflation of two distinct principles that I dub "Evidential Uniqueness" and "Rationality Uniqueness." The former principle is likely true but (...) the latter almost certainly false. Seeing why the Rationality Uniqueness fails opens the door to seeing how mutual reasonable disagreement is possible even among those who share the same evidence. (shrink)

In this paper, I aim to do three things. First, I introduce the distinction between the Uniqueness Thesis (U) and what I call the Conditional Uniqueness Thesis (U*). Second, I argue that despite their official advertisements, some prominent uniquers effectively defend U* rather than U. Third, some influential considerations that have been raised by the opponents of U misfire if they are interpreted as against U*. The moral is that an appreciation of the distinction between U (...) and U* helps to clarify the contours of the uniqueness debate and to avoid a good deal of talking past each other. (shrink)

Uniqueness appears to enhance intrinsic value. A unique stamp sells for millions of dollars; Stradivarius violins are all the more precious because they are unlike any others. This observation has not gone overlooked in the value theory literature: uniqueness plays a starring role recalibrating the dominant Moorean understanding of the nature of intrinsic value. But the thesis that uniqueness enhances intrinsic value is in tension with another deeply plausible and widely held thesis, namely the (...) class='Hi'>thesis that there is a pro tanto reason to promote the good. It is argued that there is a second, distinct type of uniqueness that plays a more interesting and important axiological role: uniqueness imparts irreplaceable value. This gives occasion to develop the surprisingly undertheorized notion of irreplaceable value. (shrink)

In this paper I offer an argument for the view that every body of evidence rationalizes exactly one doxastic attitude to each proposition. This is the uniqueness thesis. I do this by identifying a family of explanatory demands facing permissivists, those who deny the uniqueness thesis. Permissivists have traditionally motivated their view by attempting to identify counterexamples to the uniqueness thesis. But they have not developed a more general account of when permissive cases arise, (...) and why. Permissivists cannot explain why permissive cases are permissive, or how permissive they are. The paper contains three sections. First, I identify the explanatory demands facing the permissivist. Second, I survey a few existing proposals in the literature for how these explanatory demands might be answered, and argue that they fail. In the third section, I consider how permissivists might “soften” these explanatory demands, by holding that the permissible range of attitudes has vague borders, or that we do not know where its borders lie. I argue against both options. To do this, I present a general argument that there cannot be vague deontic facts, by appealing to a dominance principle and basic principles of deontic logic. If there are no deontic facts, then the permissible range of attitudes could not have vague borders, so the explanatory demands facing the permissivist remain unanswered. (shrink)

The paper presents a new argument for epistemic permissivism. The version of permissivism that we defend is a moderate version that applies only to explicit doxastic attitudes. Drawing on Yalcin’s framework for modeling such attitudes, we argue that two fully rational subjects who share all their evidence, prior beliefs, and epistemic standards may still differ in the explicit doxastic attitudes that they adopt. This can happen because two such subjects may be sensitive to different questions. Thus, differing intellectual interests can (...) yield failures of uniqueness. This is not a merely pragmatic phenomenon. (shrink)

I present an argument against the thesis of Uniqueness and in favour of Permissivism. Counterexamples to Uniqueness are provided, based on ‘Safespot’ propositions – i.e. a proposition that is guaranteed to be true provided the subject adopts a certain attitude towards it. The argument relies on a plausible principle: (roughly stated) If S knows that her believing p would be a true belief, then it is rationally permitted for S to believe p. One motivation for denying this (...) principle – viz. opposition to ‘epistemic consequentialism’ – is briefly discussed. The principle is extended to cover degrees of belief and compared with a couple of other well-known constraints on rational degrees of belief. (shrink)

White, Christensen, and Feldman have recently endorsed uniqueness, the thesis that given the same total evidence, two rational subjects cannot hold different views. Kelly, Schoenfield, and Meacham argue that White and others have at best only supported the weaker, merely intrapersonal view that, given the total evidence, there are no two views which a single rational agent could take. Here, we give a new argument for uniqueness, an argument with deliberate focus on the interpersonal element of the (...) thesis. Our argument is that the best explanation of the value of promoting rationality is an explanation that entails uniqueness. (shrink)

Evidential Uniqueness is the thesis that, for any batch of evidence, there’s a unique doxastic state that a subject with that evidence should have. One of the most common kinds of objections to views that violate Evidential Uniqueness are arbitrariness objections – objections to the effect that views that don’t satisfy Evidential Uniqueness lead to unacceptable arbitrariness. The goal of this paper is to examine a variety of arbitrariness objections that have appeared in the literature, and (...) to assess the extent to which these objections bolster the case for Evidential Uniqueness. After examining a number of different arbitrariness objections, I’ll conclude that, by and large, these objections do little to bolster the case for Evidential Uniqueness. (shrink)

Kopec and Titelbaum collect five alleged counterexamples to Uniqueness, the thesis that it is impossible for agents who have the same total evidence to be ideally rational in having different doxastic attitudes toward the same proposition. I argue that four of the alleged counterexamples fail, and that Uniqueness should be slightly modified to accommodate the fifth example.

The purpose of this paper is to challenge what is often called the “Uniqueness” thesis. According to this thesis, given one’s total evidence, there is a unique rational doxastic attitude that one can take to any proposition. It is sensible for defenders of Uniqueness to commit to an accompanying principle that: when some agent A has equal epistemic reason both to believe that p and to believe that not p, the unique epistemically rational doxastic attitude for (...) A to adopt with respect to whether p is the suspension of judgment. In this paper, I offer a case wherein the agent has equal epistemic reason both to believe that p and to believe that not p, but the agent is not epistemically required to suspend judgment about whether p. Furthermore, the case is such that there seems to be no uniquely rational attitude for the agent to adopt. (shrink)

According to the proponents of Developmental Systems Theory and the Causal Parity Thesis, the privileging of the genome as “first among equals” with respect to the development of phenotypic traits is more a reflection of our own heuristic prejudice than of ontology - the underlying causal structures responsible for that specified development no more single out the genome as primary than they do other broadly “environmental” factors. Parting with the methodology of the popular responses to the Thesis, this (...) paper offers a novel criterion for ‘causal primacy’, one that is grounded in the ontology of the unique causal role of dispositional properties. This paper argues that, if the genome is conceptualised as realising dispositional properties that are “directed toward” phenotypic traits, the parity of ‘causal roles’ between genetic and extra-genetic factors is no longer apparent, and further, that the causal primacy of the genome is both plausible and defensible.

If the reliability of a source of testimony is open to question, it seems epistemically illegitimate to verify the source’s reliability by appealing to that source’s own testimony. Is this because it is illegitimate to trust a questionable source’s testimony on any matter whatsoever? Or is there a distinctive problem with appealing to the source’s testimony on the matter of that source’s own reliability? After distinguishing between two kinds of epistemically illegitimate circularity—bootstrapping and self-verification—I argue for a qualified version of (...) the claim that there is nothing especially illegitimate about using a questionable source to evaluate its own reliability. Instead, it is illegitimate to appeal to a questionable source’s testimony on any matter whatsoever, with the matter of the source’s own reliability serving only as a special case. (shrink)

It is well known in contemporary Madhyamaka studies that the seventh century Indian philosopher Candrakīrti rejects the foundationalist Abhidharma epistemology. The question that is still open to debate is: Does Candrakīrti offer any alternative Madhyamaka epistemology? One possible way of addressing this question is to find out what Candrakīrti says about the nature of buddha’s epistemic processes. We know that Candrakīrti has made some puzzling remarks on that score. On the one hand, he claims buddha is the pramāṇabhūta-puruṣa (person of (...) epistemic and moral authority), sarvākārajñatājñānaṃ (omniscient, wise), pratyakṣalakṣaṇam (exclusively perceptual in characteristic) [Candrakīrti (MABh VI.214)], and claims that there are clearly four pramāṇas—epistemic warrants—direct perception (pratyakṣa), inference (anumāna), testimony (āgama) and analogy (upamāna) [Candrakīrti (Pp I.3), cf. MacDonald 2015, pp. 287–288]. On the other hand, somewhat paradoxically, Candrakīrti claims that buddhahood is an embodiment of a complete cessation of “mind and mental processes” [Candrakīrti (MABh XI.1, 155a; MAB XI.17d)] Now how are we to make sense of these two seemingly contradictory statements? Do these statements reflect any deeper conflicts within Candrakīrti’s system or is there a coherent way to interpret these statements? The Tibetan Prāsaṅgika interpreters of Candrakīrti’s Madhyamaka largely agree that there is no internal contradiction in Candrakīrti’s system, and agree there is a way to make coherent sense of these statements. Nevertheless, the Tibetans exegetes bring to the table two radically conflicting proposals to approach Candrakīrti’s Mādhyamaka; both claiming to successfully address the apparent tension arising from Candrakīrti’s statements. One proposal is made by Tsongkhapa Losang Dakpa (Tsong kha pa bLo bzang grags pa, 1357–1419), who maintains the tension can be plausibly resolved by demonstrating that Candrakīrti’s unique non-foundationalist epistemological program renders him an epistemological coherentist. In contrast Taktsang Lotsawa Sherap Rinchen (sTag tshang Lo tsā ba Shes rab rin chen, 1405–1477) argues that according to Candrakīrti buddha is a global agnostic, on the ground of the nonexistence of mind and mental processes for those who have attained fully awakening. Taktsang instead proposes the no-mind thesis as a more plausible way to resolve the tension in Candrakīrti’s philosophy, categorically refusing to attribute to buddha any cognitive processes and epistemic warrants. This paper is an analysis of Taktsang’s no-mind thesis—the claim that buddhas utterly lack any knowledge of the world because they do not have epistemic processes and warrants to perceive the world—in what follows a rational reconstruction of his arguments is developed in order to evaluate his thesis. We shall then assess the implications of accepting Taktsang’s no-mind thesis. (shrink)

The thesis deals with the concept of truth and the paradoxes of truth. Philosophical theories usually consider the concept of truth from a wider perspective. They are concerned with questions such as - Is there any connection between the truth and the world? And, if there is - What is the nature of the connection? Contrary to these theories, this analysis is of a logical nature. It deals with the internal semantic structure of language, the mutual semantic connection of (...) sentences, above all the connection of sentences that speak about the truth of other sentences and sentences whose truth they speak about. Truth paradoxes show that there is a problem in our basic understanding of the language meaning and they are a test for any proposed solution. It is important to make a distinction between the normative and analytical aspect of the solution. The former tries to ensure that paradoxes will not emerge. The latter tries to explain paradoxes. Of course, the practical aspect of the solution is also important. It tries to ensure a good framework for logical foundations of knowledge, for related problems in Artificial Intelligence and for the analysis of the natural language. Tarski’s analysis emphasized the T-scheme as the basic intuitive principle for the concept of truth, but it also showed its inconsistency with the classical logic. Tarski’s solution is to preserve the classical logic and to restrict the scheme: we can talk about the truth of sentences of a language only inside another essentially richer metalanguage. This solution is in harmony with the idea of reflexivity of thinking and it has become very fertile for mathematics and science in general. But it has normative nature | truth paradoxes are avoided in a way that in such frame we cannot even express paradoxical sentences. It is also too restrictive because, for the same reason we cannot express a situation in which there is a circular reference of some sentences to other sentences, no matter how common and harmless such a situation may be. Kripke showed that there is no natural restriction to the T-scheme and we have to accept it. But then we must also accept the riskiness of sentences | the possibility that under some circumstances a sentence does not have the classical truth value but it is undetermined. This leads to languages with three-valued semantics. Kripke did not give any definite model, but he gave a theoretical frame for investigations of various models | each fixed point in each three-valued semantics can be a model for the concept of truth. The solutions also have normative nature | we can express the paradoxical sentences, but we escape a contradiction by declaring them undetermined. Such a solution could become an analytical solution only if we provide the analysis that would show in a substantial way that it is the solution that models the concept of truth. Kripke took some steps in the direction of finding an analytical solution. He preferred the strong Kleene three-valued semantics for which he wrote it was "appropriate" but did not explain why it was appropriate. One reason for such a choice is probably that Kripke finds paradoxical sentences meaningful. This eliminates the weak Kleene three valued semantics which corresponds to the idea that paradoxical sentences are meaningless, and thus indeterminate. Another reason could be that the strong Kleene three valued semantics has the so-called investigative interpretation. According to this interpretation, this semantics corresponds to the classical determination of truth, whereby all sentences that do not have an already determined value are temporarily considered indeterminate. When we determine the truth value of these sentences, then we can also determine the truth value of the sentences that are composed of them. Kripke supplemented this investigative interpretation with an intuition about learning the concept of truth. That intuition deals with how we can teach someone who is a competent user of an initial language (without the predicate of truth T) to use sentences that contain the predicate T. That person knows which sentences of the initial language are true and which are not. We give her the rule to assign the T attribute to the former and deny that attribute to the latter. In that way, some new sentences that contain the predicate of truth, and which were indeterminate until then, become determinate. So the person gets a new set of true and false sentences with which he continues the procedure. This intuition leads directly to the smallest fixed point of strong Kleene semantics as an analytically acceptable model for the logical notion of truth. However, since this process is usually saturated only on some transfinite ordinal, this intuition, by climbing on ordinals, increasingly becomes a metaphor. This thesis is an attempt to give an analytical solution to truth paradoxes. It gives an analysis of why and how some sentences lack the classical truth value. The starting point is basic intuition according to which paradoxical sentences are meaningful (because we understand what they are talking about well, moreover we use it for determining their truth values), but they witness the failure of the classical procedure of determining their truth value in some "extreme" circumstances. Paradoxes emerge because the classical procedure of the truth value determination does not always give a classically supposed (and expected) answer. The analysis shows that such an assumption is an unjustified generalization from common situations to all situations. We can accept the classical procedure of the truth value determination and consequently the internal semantic structure of the language, but we must reject the universality of the exterior assumption of a successful ending of the procedure. The consciousness of this transforms paradoxes to normal situations inherent to the classical procedure. Some sentences, although meaningful, when we evaluate them according to the classical truth conditions, the classical conditions do not assign them a unique value. We can assign to them the third value, \undetermined", as a sign of definitive failure of the classical procedure. An analysis of the propagation of the failure in the structure of sentences gives exactly the strong Kleene three-valued semantics, not as an investigative procedure, as it occurs in Kripke, but as the classical truth determination procedure accompanied by the propagation of its own failure. An analysis of the circularities in the determination of the classical truth value gives the criterion of when the classical procedure succeeds and when it fails, when the sentences will have the classical truth value and when they will not. It turns out that the truth values of sentences thus obtained give exactly the largest intrinsic fixed point of the strong Kleene three-valued semantics. In that way, the argumentation is given for that choice among all fixed points of all monotone three-valued semantics for the model of the logical concept of truth. An immediate mathematical description of the fixed point is given, too. It has also been shown how this language can be semantically completed to the classical language which in many respects appears a natural completion of the process of thinking about the truth values of the sentences of a given language. Thus the final model is a language that has one interpretation and two systems of sentence truth evaluation, primary and final evaluation. The language through the symbol T speaks of its primary truth valuation, which is precisely the largest intrinsic fixed point of the strong Kleene three valued semantics. Its final truth valuation is the semantic completion of the first in such a way that all sentences that are not true in the primary valuation are false in the final valuation. (shrink)

The extended mind thesis states that the mind is not brain-bound but extends into the physical world. The philosophical debate around the thesis has mostly focused on extension towards epistemic artefacts, treating the phenomenon as a special capacity of the human organism to recruit external physical resources to solve individual tasks. This paper argues that if the mind extends to artefacts in the pursuit of individual tasks, it extends to other humans in the pursuit of collective tasks. Mind (...) extension to other humans corresponds essentially to the ‘we-mode’ of cognition, the unique power of human minds to be jointly directed at goals, intentions, states of affairs, or values. Because the capacity for collective intentionality holds evolutionary and developmental primacy over human-epistemic artefacts relations, the extended mind should not be seen as a special phenomenon, but as a central aspect of the human condition. The original extended mind thesis carried important implications for how the cognitive sciences should proceed. In a version of the thesis that accommodates collective intentionality, these implications would go far deeper than originally assumed. (shrink)

The lie detector test has long been treated with suspicion by the law. Recently, several authors have called this suspicion into question. They argue that the lie detector test may have considerable forensic benefits, particularly if we move past the classic, false-positive prone, autonomic nervous system-based (ANS-based) control question test, to the more reliable, brain-based, concealed information test. These authors typically rely on a “comparative advantage” argument to make their case. According to this argument, we should not be so suspicious (...) of lie detection evidence if it has comparative advantages over the epistemic methods currently utilised by the legal system. In this article, I add to this growing support by making a novel comparative advantage argument in favour of brain-based lie detection evidence. The argument focuses on the P300 concealed information test (P300 CIT), which has several unique properties, and on the effect it may have on pre-trial bargaining in criminal cases rather than in-court evidence. The thesis is that P300 CIT could allow for innocent defendants to credibly signal their innocence to investigators and prosecutors during pre-trial bargaining more effectively than current proposed methods for doing the same thing. I defend this argument from a number of objections, and suggest that it opens up an interesting avenue in the ongoing debate about the merits of this technology. Although the argument is presented with the criminal law in mind, it could form part of a more general cumulative case in favour of this technology. (shrink)

The central thesis of this paper is that the scope and structure of Hume's Treatise of Human Nature is modelled, or planned, after that of Hobbes's The Elements of Law and that in this respect there exists an important and unique relationship between these works. This relationship is of some importance for at least two reasons. First, it is indicative of the fundamental similarity between Hobbes's and Hume's project of the study of man. Second, and what is more important, (...) by recognizing this relationship between Hume's and Hobbes's works we can come to appreciate the unity of the project of the Treatise itself. My discussion will proceed in three stages. In section I present the evidence for my central thesis. In the second section I shall consider why Hume does not, as one might expect, acknowledge this important debt to Hobbes in the Introduction to the Treatise or in the Abstract. Finally, in the third section I shall note a few points of some importance to the understanding of Hume's philosophy which this relationship between Hobbes's and Hume's work touches upon. (shrink)

A god is a cosmic designer-creator. Atheism says the number of gods is 0. But it is hard to defeat the minimal thesis that some possible universe is actualized by some possible god. Monotheists say the number of gods is 1. Yet no degree of perfection can be coherently assigned to any unique god. Lewis says the number of gods is at least the second beth number. Yet polytheists cannot defend an arbitrary plural number of gods. An alternative is (...) that, for every ordinal, there is a god whose perfection is proportional to it. The n -th god actualizes the best universe(s) in the n -th level of an axiological hierarchy of possible universes. Despite its unorthodoxy, ordinal polytheism has many metaphysically attractive features and merits more serious study. (shrink)

In his essay “Things Do Not Move,” Sengzhao (374?−414 CE), a prominent Chinese Buddhist philosopher, argues for the thesis that the myriad things do not move in time. This view is counter-intuitive and seems to run counter to the Mahayana Buddhist doctrine of emptiness. In this book chapter, I assess Sengzhao’s arguments for his thesis, elucidate his stance on the change/nonchange of things, and discuss related problems. I argue that although Sengzhao is keen on showing the plausibility of (...) the thesis, he actually views the myriad things as both changing and unchanging and upholds the nonduality of motion and rest. In fact, the nonmoving thesis follows from the discernment that things change from moment to moment without there being any enduring stuff in the process. Among philosophical works that confer a higher ontological status on nonchange over change, Sengzhao’s essay is unique and well worth pondering. (shrink)

This paper defends an interpretation of Gottlob Frege’s views on the structure of thought. I argue that Frege did not think that a thought has a unique decomposition into its component senses, but rather the same thought can be decomposed into senses in multiple, distinct ways. These multiple decompositions will often have distinct logical forms. I also argue against Michael Dummett and others that Frege was committed to the sense of a predicate being a function from the sense of a (...) name (or names) to a complete thought. I defend my Frege interpretation against a puzzle often discussed in the Frege literature; namely, that the Multiple Decompositions Thesis is incompatible with Frege’s stated view that a thought is built up out of its component senses as parts. I provide textual evidence and argument that Frege thought of the part/whole relation in such a way that a whole can be analyzed into (or built up out of) parts in multiple, distinct ways, thus dissolving the puzzle. I conclude with discussion of every sort of example of multiple decompositions that can be found in Frege's work. (shrink)

[EDIT: This book will be published open access. Check back around April 2024 to access the entire book.] One central aim of science is to provide explanations of natural phenomena. What role(s) does mathematics play in achieving this aim? How does mathematics contribute to the explanatory power of science? Rules to Infinity defends the thesis, common though perhaps inchoate among many members of the Vienna Circle, that mathematics contributes to the explanatory power of science by expressing conceptual rules, rules (...) which allow the transformation of empirical descriptions. Mathematics should not be thought of as describing, in any substantive sense, an abstract realm of eternal mathematical objects, as traditional platonists have thought. In Rules to Infinity, this view, which I call mathematical normativism, is updated with contemporary philosophical tools, and it is argued that normativism is compatible with mainstream semantic theory. This allows the normativist to accept that there are mathematical truths, while resisting the platonistic idea that there exist abstract mathematical objects that explain such truths. Furthermore, Rules to Infinity defends a particular account of the distinction between scientific explanations that are in some sense distinctively mathematical – those that explain natural phenomena in some uniquely mathematical way – and those that are only standardly mathematical, and it lays out desiderata for any account of this distinction. Normativism is compared with other prominent views in the philosophy of mathematics such as neo-Fregeanism, fictionalism, conventionalism, and structuralism. Rules to Infinity serves as an entry point into debates at the forefront of philosophy of science and mathematics, and it defends novel positions in these debates. (shrink)

Moral reasoning traditionally distinguishes two types of evil:moral (ME) and natural (NE). The standard view is that ME is the product of human agency and so includes phenomena such as war,torture and psychological cruelty; that NE is the product of nonhuman agency, and so includes natural disasters such as earthquakes, floods, disease and famine; and finally, that more complex cases are appropriately analysed as a combination of ME and NE. Recently, as a result of developments in autonomous agents in cyberspace, (...) a new class of interesting and important examples of hybrid evil has come to light. In this paper, it is called artificial evil (AE) and a case is made for considering it to complement ME and NE to produce a more adequate taxonomy. By isolating the features that have led to the appearance of AE, cyberspace is characterised as a self-contained environment that forms the essential component in any foundation of the emerging field of Computer Ethics (CE). It is argued that this goes someway towards providing a methodological explanation of why cyberspace is central to so many of CE's concerns; and it is shown how notions of good and evil can be formulated in cyberspace. Of considerable interest is how the propensity for an agent's action to be morally good or evil can be determined even in the absence of biologically sentient participants and thus allows artificial agents not only to perpetrate evil (and fort that matter good) but conversely to `receive' or `suffer from' it. The thesis defended is that the notion of entropy structure, which encapsulates human value judgement concerning cyberspace in a formal mathematical definition, is sufficient to achieve this purpose and, moreover, that the concept of AE can be determined formally, by mathematical methods. A consequence of this approach is that the debate on whether CE should be considered unique, and hence developed as a Macroethics, may be viewed, constructively,in an alternative manner. The case is made that whilst CE issues are not uncontroversially unique, they are sufficiently novel to render inadequate the approach of standard Macroethics such as Utilitarianism and Deontologism and hence to prompt the search for a robust ethical theory that can deal with them successfully. The name Information Ethics (IE) is proposed for that theory. Itis argued that the uniqueness of IE is justified by its being non-biologically biased and patient-oriented: IE is an Environmental Macroethics based on the concept of data entity rather than life. It follows that the novelty of CE issues such as AE can be appreciated properly because IE provides a new perspective (though not vice versa). In light of the discussion provided in this paper, it is concluded that Computer Ethics is worthy of independent study because it requires its own application-specific knowledge and is capable of supporting a methodological foundation, Information Ethics.

Abstract. Richard Feldman’s Uniqueness Thesis holds that “a body of evidence justifies at most one proposition out of a competing set of proposi- tions”. The opposing position, permissivism, allows distinct rational agents to adopt differing attitudes towards a proposition given the same body of evidence. We assess various motivations that have been offered for Uniqueness, including: concerns about achieving consensus, a strong form of evidentialism, worries about epistemically arbitrary influences on belief, a focus on truth-conduciveness, and consequences (...) for peer disagreement. We argue that each of these motivations either misunderstands the commitments of permissivism or is question-begging. Better understanding permissivism makes it a much more plausible position.

Stoic philosophers had to face the accusation of incoherence, self-contradiction and Paradoxes since ancient times. Plutarch in his Moralia writes against them; Cicero devotes a separate work on stoic paradoxes. Even in contemporary Literature there are still discussions on the possibility of such an incoherence and existence of paradoxes in the stoic theory. At first glance, stoic Cosmology gives the impression to both accept a kind of Determinism, and at the same time it undoubtedly argues for the moral agent’s freedom (...) of the Will. In pre-stoic or even other contemporary to Stoicism Philosophical Traditions, the definitions that these two terms/concepts are given, fairly accuse as incoherent any Theory that does not set them as “contraries”. Under these types of accusations, the stoic Cosmology and Theory of the Freedom of the Will is often to be included. This phenomenal self-contradiction inside the Principles of Stoicism becomes even more obvious in Epictetus, a philosopher of the Late Stoa. He is interested in practical ethics, thus the phenomenal contradiction gets more lucid. This would have augmented the criticism of the Stoic philosophy for incoherence, if Epictetus had not made his main philosophical aim/target : the clarification of how an agent’s Will can be Free inside a Universe ruled by Fate/Destiny ; namely, a Universe merely Determined by Nature’s/God’s Will. Epictetus’ originality appears in the way he interrelates the concept of Freedom of the Will with the concept of Destiny and Determinism, in order to accomplish their simultaneous co-existence. This approach guards him against being easily accused for incoherence and self-contradiction. Through the unique way he understands and defines the Moral Agency, which is the agent’s internal state/condition/disposition, he steers towards an integrated, accomplished, strong and coherent line of argument. This sturdy declaration is able to support the weight of the Consent to a Free Will, and thus a certain kind Freedom of the moral agent. The excellence of this line of argument is that it can bear also the burden of the Consent to the phenomenally contrary concept of Determinism and Destiny. The elements used to the construction of this argument, which is stretched throughout the whole epictetean corpus can be summarised to a few key concepts, which are: the things which are in our power and the things which are not in our power, the concept of Freedom. These concepts work towards his philosophical targeting, because of the special definition he gives them. Axiomatically Epictetus states that in order for man to be free, it is necessary to be liberated from what the body forces him to do. Desires, passions and beliefs are considered as elements which are external to the moral agent. The moral agent “shrinks” into the Will. Thus man has the capability to free himself from anything external to his Will and therefore to harmonise his own Will to the Will of Nature/God; namely, to will what Nature/God wills and thus never conflict to the external facts. Consequently, Epictetus’ solution, is to include in the category of τά οὐκ ἐφ' ἡμῖν anything that he defines as external to the prohairesis: the desires, beliefs, passions and in general anything the body entails, the external facts. Thus the prohairesis, remains unhindered and it is completely depended on man’s power ; as characteristically Epictetus writes, “not even Zeus himself can overpower” the prohairesis. -/- Dissertation for the MSc Ancient Philosophy (2008-2009) at The University of Edinburgh, supervised by Inna Kupreeva.

Moral reasoning traditionally distinguishes two types of evil: moral and natural. The standard view is that ME is the product of human agency and so includes phenomena such as war, torture and psychological cruelty; that NE is the product of nonhuman agency, and so includes natural disasters such as earthquakes, floods, disease and famine; and finally, that more complex cases are appropriately analysed as a combination of ME and NE. Recently, as a result of developments in autonomous agents in cyberspace, (...) a new class of interesting and important examples of hybrid evil has come to light. In this paper, it is called artificial evil and a case is made for considering it to complement ME and NE to produce a more adequate taxonomy. By isolating the features that have led to the appearance of AE, cyberspace is characterised as a self-contained environment that forms the essential component in any foundation of the emerging field of Computer Ethics. It is argued that this goes some way towards providing a methodological explanation of why cyberspace is central to so many of CE’s concerns; and it is shown how notions of good and evil can be formulated in cyberspace. Of considerable interest is how the propensity for an agent’s action to be morally good or evil can be determined even in the absence of biologically sentient participants and thus allows artificial agents not only to perpetrate evil but conversely to ‘receive’ or ‘suffer from’ it. The thesis defended is that the notion of entropy structure, which encapsulates human value judgement concerning cyberspace in a formal mathematical definition, is sufficient to achieve this purpose and, moreover, that the concept of AE can be determined formally, by mathematical methods. A consequence of this approach is that the debate on whether CE should be considered unique, and hence developed as a Macroethics, may be viewed, constructively, in an alternative manner. The case is made that whilst CE issues are not uncontroversially unique, they are sufficiently novel to render inadequate the approach of standard Macroethics such as Utilitarianism and Deontologism and hence to prompt the search for a robust ethical theory that can deal with them successfully. The name Information Ethics is proposed for that theory. It is argued that the uniqueness of IE is justified by its being non-biologically biased and patient-oriented: IE is an Environmental Macroethics based on the concept of data entity rather than life. It follows that the novelty of CE issues such as AE can be appreciated properly because IE provides a new perspective. In light of the discussion provided in this paper, it is concluded that Computer Ethics is worthy of independent study because it requires its own application-specific knowledge and is capable of supporting a methodological foundation, Information Ethics.

I examine the origins of ordinary racial thinking. In doing so, I argue against the thesis that it is the byproduct of a unique module. Instead, I defend a pluralistic thesis according to which different forms of racial thinking are driven by distinct mechanisms, each with their own etiology. I begin with the belief that visible features are diagnostic of race. I argue that the mechanisms responsible for face recognition have an important, albeit delimited, role to play in (...) sustaining this belief. I then argue that essentialist beliefs about race are driven by some of the mechanisms responsible for “entitativity perception”: the tendency to perceive some aggregates of people as more genuine groups than others. Finally, I argue that coalitional thinking about race is driven by a distinctive form of entitativity perception. However, I suggest that more data is needed to determine the prevalence of this form of racial thinking. (shrink)

The A-theory and the B-theory advance competing claims about how time is grounded. The A-theory says that A-facts are more fundamental in grounding time than are B-facts, and the B-theory says the reverse. We argue that whichever theory is true of the actual world is also true of all possible worlds containing time. We do this by arguing that time is uniquely groundable: however time is actually grounded, it is necessarily grounded in that way. It follows that if either the (...) A-theory or the B-theory is actually false, then it is necessarily false. (shrink)

This paper provides a qualified defense of Martin Heidegger’s controversial assertion that humans and animals differ in kind, not just degree. He has good reasons to defend the human difference, and his thesis is compatible with the evolution of humans from other animals. He argues that the human environment is the world of meaning and truth, an environment which peculiarly makes possible truthful activities such as biology. But the ability to be open to truth cannot be a feature of (...) human biology, without making such pursuits as biology, mathematics, and philosophy a biological function of a certain species, homo sapiens. To deny the human difference amounts to species relativism which leaves the normativity of truth unexplained. To reconcile the human evolutionary heritage and the uniquely human openness to meaning and truth, the paper amplifies a distinction occasionally made by Heidegger between condition and cause.

This doctoral thesis examines the phenomenon of Filipinization, specifically understood as the ideological construction of a “Filipino identity” or ‘Filipino subject-consciousness” within the highly determinate context provided by the Filipino ilustrado nationalists such as José Rizal, Marcelo H. del Pilar and their fellow propagandists inasmuch as it leads to the nineteenth (19th) century construction of the modern Philippine nation. Utilizing Jacques Derrida’s deconstructive thinking, this study undertakes a genealogical critique engaged on the concrete historical examination of what is meant (...) by the term “Filipino” across a select historical timeline (1864-1898) and the various notions of Filipino identity implied by the different contexts within which the term “Filipino” has been employed. More specifically, it undertakes a selective philosophical excavation of three seminal texts in the history of Filipinization, viz.: 1) the Manifiesto of Padre Jose Burgos; 2) the writings of the Filipino ilustrados in La Solidaridad; and 3) Jose Rizal’s Annotations on Dr. Antonio de Morga’s Sucesos de las Islas Filipinas. -/- The philosophical claim of this work is the idea that Filipinization, taken as the differential construction of Filipino identity, is the effective translation of the colonial epistemic violence of Eurocentric racism and its consequent “horror of absolutism” into the homo-hegemony of Filipino nationalisms. By fetishizing the notion of a carefully constructed and essential “Filipino-identity,” Filipinization and the current nationalist discourses that utilize them, unwittingly, stands complicit with the same colonial violence and hegemony that they wish to combat. This happens precisely when the very structures of colonial oppression, on the ideological and practical levels, are transmogrified into nationalist ideals that assume legal and political power unto themselves in a self-referential and self-legitimating fashion. -/- Three processes will demonstrate the above thesis: first, by examining historical texts and setting itself against established nationalist historiographies, a genealogical analysis of the term “Filipino” reveals it as a pliable signifier whose semantics have evolved through time. From its originary referent in the Spanish criollo (creole), it has come to refer to people who would have been otherwise entirely alien to this class, viz., the mestizos (both Spanish and Chinese), the principalia (native elite), and eventually, the lowland Catholicized natives themselves. The historical hermeneutic of this identity-discourse in Padre José Burgos’ Manifiesto yields the fact that what gives the term “Filipino” its semantic consistency as a class concept is its essential constitution as a Hispanic and Catholic identity. -/- Second, from this semantic identification of the term “Filipino” as a Hispano-Catholic identity, we proceed to clarify the meaning of Filipinization in terms of the nationalist propaganda carried out by the Filipino ilustrados in the fortnightly periodical La Solidaridad. Here, the specific ilustrado construction of Filipino identity as a Spanish citizen (ciudadano Español) is revealed precisely as a political and legal construct that served as the basis for their own politics of social inclusion/exclusion. Filipinization can only be applied to those who have been hispanized and Christianized and never to those tribes who have resisted and remained outside Spanish colonial authority. Filipinization is thus revealed as a process of Hispanization and Christianization whereby the recipients of Spanish colonial hegemony are transformed into the religiously docile bodies of the Spanish Empire. -/- From this highly determinate context, the study proceeds to examine Rizal’s ontological grounding of collective Filipino-ness in the mythological construction of the pre-hispanic past as the source of a unique Filipino ancestrality. In his work on de Morga’s Sucesos, what is revealed is a mythologization that grounds a native, essential Filipino identity within a past unscathed by the Spanish colonial experience. Such mythologization, however, can only be possible through an anachronistic nationalist interpretation of historical data. Here, Filipinization is revealed as an exclusive prerogative, a nationalist program by which Rizal and the ilustrado class can combat the evils and excesses of the Spanish colonial enterprise. Ironically, though, this same struggle for emancipation also became an instrument by which the ilustrado class can retain their unjustified position of power over those who belonged to the colonial underside, thus, securing the possibility of perpetuating their own ilustrado bourgeois class interests. -/- Such discursive complicity is the essence of the myth of Filipinization: it presents nationalist identity discourse as an anti-colonial enterprise while being underlined by an economy of motives designed to cater primarily to the exclusive interests of the elite and ilustrado class. Thus, instead of securing the genuine, inclusive emancipation of all colonial subjects and a more humane existence for the poor and suffering majority, ilustrado nationalism has, ironically, merely reinforced those operative structures of colonial discrimination and oppression when the ilustrados: 1) grounded their racial theory upon the very same discourse of Eurocentric superiority that they are precisely supposed to question and 2) claimed a patrimony over Filipinas as their exclusive sovereign inheritance. These two factors illustrate how the manifest transfer of power from the Spanish Empire to the Philippine sovereign nation (and later as a nation-state) illustrate how Filipinization merely has transmogrified the face of Spanish colonialism into its new, subtle, and worse form in Filipino nationalism. -/- In this vein, the existence of the 19th century modern Philippine nation merely masked and deferred the crisis that was supposed to transfer power from the Spanish Empire to the multitude of the poor and suffering native indio majority. This crisis became all the more difficult to address be-cause of the duplicitous character of the discourse of Filipinization itself. It has not only effectively transferred power into the hands of the nationalist elite but also captured authentic emancipatory discourse within the identity-trap against which it can only hope to get out. This study concludes with the claim about the impossibility of ever escaping and overcoming the epistemic and practical violence necessarily contained within the historical discourse of colonialism. Or simply, we have no language or discourse that would enable us to overcome the complicity of Filipinization with the very (epistemic) violence against which it has set itself. (shrink)

The Situationist International (1957-1972) was a small group of communist revolutionaries, originally organised out of the West European artistic avant-garde of the 1950s. The focus of my thesis is to explain how the Situationist International (SI) became a group able to exert a considerable influence on the ultra-left criticism that emerged during and in the wake of the May movement in France in 1968. My wager is that the pivotal period of the group is to be found between 1960 (...) and 1963, a period marked by the split of 1962. Often this is described as the transition of the group from being more concerned with art to being more concerned with politics, but as I will argue this definitional shorthand elides the significance of the Situationist critique of art, philosophy and politics. The two axes of my thesis are as follows. First, that the significant minority in the group which carried out the break of 1962, identified a homology between the earlier Situationist critique of art — embodied in the Situationist ‘hypothesis of the construction of situations’ — and Marx’s critique and supersession of the radical milieu of philosophy from which he emerged in the mid- 1840s. This homology was summarised in the expression of the Situationist project as the ‘supersession of art’ (dépassement de l’art). Secondly, this homology was practically embodied in the resolution of the debates over the role of art in the elaboration of the Situationist hypothesis, which had been ongoing since 1957. However, it was the SI’s encounter with the ultra-left group Socialisme ou Barbarie that would prove decisive. Via Guy Debord’s membership, the group was exposed to both the idea of a more general revolutionary criticism, but also ultimately what was identified as the insufficiently criticised ‘political militancy’ of this group. Indeed, in the ‘political alienation’ found in Socialisme ou Barbarie, a further homology was established between the alienation of the political and artistic avant-gardes. This identity would prove crucial to the further elaboration of the concept of ‘spectacle’. By way of an examination of the peculiar and enigmatic ‘Hamburg Theses’ of 1961, and the relationship between these ‘Theses’ and the Situationist criticism of art and politics worked out over the first five years of the group, I will argue that the break in 1962 should be conceived as one against politics as much as art (rather than just the latter, as it is more often represented). Additionally, I will outline how the SI, through the paradoxical reassertion of their artistic origins, attempted to synthesise their criticism of art with the recovery of the work of Marx beyond its mutilation as Marxism. Indeed, it was the synthesis of these critiques that enabled the considerable development of the concept of ‘spectacle’, opening the way to the unique influence the SI exerted in the re-emergence of a revolutionary movement at the end of the 1960s.

Episodic and semantic memory are often taken to be fundamentally different mental systems, and contemporary philosophers often pursue research questions about episodic memory, in particular, in isolation from semantic memory. This paper challenges that assumption, and puts pressure on philosophical approaches to memory that break off episodic memory as its own standalone topic. I present and systematize psychological and neuroscientific theories of semanticization, the thesis that memory content tends to drift from episodic to semantic in structure over time and (...) exposure to an environment. Semanticization, I argue, is a long-term interconnection between episodic and semantic systems that requires approaching both the content and function of these two memory systems as a whole. Thus we have a reason to reject projects by Michael Martin, which aims to carve out a uniquely episodic memory content, and Kourken Michaelian, which pairs episodic memory to its own unique function. Instead, seeing declarative memory as a single system with two facets or even a continuum of features allows for deeper insight into both content and function. (shrink)

Illusionism about phenomenal consciousness is the thesis that phenomenal consciousness does not exist, even though it seems to exist. This thesis is widely judged to be uniquely counterintuitive: the idea that consciousness is an illusion strikes most people as absurd, and seems almost impossible to contemplate in earnest. Defenders of illusionism should be able to explain the apparent absurdity of their own thesis, within their own framework. However, this is no trivial task: arguably, none of the illusionist (...) theories currently on the market is able to do this. I present a new theory of phenomenal introspection and argue that it might deal with the task at hand. (shrink)

It is widely held by commentators that in the Protagoras, Socrates attempts to explain the experience of mental conflict and weakness of the will without positing the existence of irrational desires, or desires that arise independently of, and so can conflict with, our reasoned conception of the good. In this essay, I challenge this commonly held line of thought. I argue that Socrates has a unique conception of an irrational desire, one which allows him to explain the experience of mental (...) conflict and weakness of the will, while still holding the Socratic thesis that we always do what we think is good. The resulting picture is both psychologically plausible and philosophically distinctive. (shrink)

The Qualitative Thesis says that if you leave open P, then you are sure of if P, then Q just in case you are sure of the corresponding material conditional. We argue the Qualitative Thesis provides compelling reasons to accept a thesis that we call Conditional Locality, which says, roughly, the interpretation of an indicative conditional depends, in part, on the conditional’s local embedding environment. In the first part of the paper, we present an argument—due to Ben (...) Holguín—showing that, without Conditional Locality, the Qualitative Thesis is in tension with a margin for error principle on rational sureness. We show Conditional Locality reconciles the Qualitative Thesis with the margin for error principle. In the second part, we argue the full range of data supports what we call the Strong Qualitative Thesis. Without Conditional Locality, the Strong Qualitative Thesis has unacceptable consequences. But with Conditional Locality, it is tenable. (shrink)

The cultural practice of flirtation has been multifariously scrutinized in various disciplines including sociology, psychology, psychoanalysis and literary studies. This paper frames the field of flirtation in Bourdieuian terms, while focusing narrowly on the semiotic economy that is defining of this cultural field. Moreover, seduction, as a uniquely varied form of discourse that is responsible for producing the cultural field of flirtation, is posited as the missing link for understanding why flirtation may be a peculiar case of non-habitus, contrary to (...) the received notion of cultural field as set of goaloriented practices and actionable habituses. This argument is pursued by highlighting the endemic traits of ambivalence and constant reversibility of signs or multimodal semiotic constellations in the discourse of seduction, while seeking to demonstrate that seduction, and by implication the cultural field of flirtation, does not necessarily partake of a teleological framework that is geared towards the consummation of sexual desire. This thesis is illustrated by recourse to a scene from the blockbuster ‘Hitch’. (shrink)

In searching for the origins of current conceptions of science in the history of physics, one encounters a remarkable phenomenon. A typical view today is that theoretical knowledge-claims have only relativized validity. Historically, however, this thesis was supported by proponents of a conception of nature that today is far from typical, a mechanistic conception within which natural phenomena were to be explained by the action of mechanically moved matter. Two of these proponents, Hermann von Helmholtz and his pupil Heinrich (...) Hertz, contributed significantly to the modernization of the conception of science. Paradigmatic for their common contribution to this development is the way in which they employed the concept of image. By considering the origin and the different meanings of this concept we may trace a line of development which begins with Helmholtz's original claim that a universally and forever valid theory provides a unique representation of nature. It continues with the realization that the status of scientific knowledge is capable of revision; and it arrives at Hertz's admission that a variety of theories over a domain of objects is possible, at least at times.

One of the leading concerns animating current philosophy of mind is that, no matter how good a scientific account is, it will leave out what its like to be conscious. The challenge has thus been to study or at least explain away that qualitative dimension. Pursuant with that aim, I investigate how philosophy of signs in the Peircean tradition can positively reshape ongoing debates. Specifically, I think the account of iconic or similarity-based reference we find in semiotic theory offers a (...) more promising variant of the phenomenal concept strategy. Philosophers who endorse this strategy think that the difficulties we have fitting conscious qualia into a scientific picture may owe to the peculiar nature of indexical concepts. They point to the fact that, when we try to convey the feel of our experiences, we employ context-dependent gestures and/or utterances that are indexed to perspectives unique to each person. However, according to the theory I defend, there are three ways signs can refer, namely by convention, causal contact, and similarity. Since similarity is not reducible to proximity, I argue that a theory of reference that turns on shared quality can bypass some of the implausible consequences that plague indexical accounts. In the first chapter, I describe the apparatus needed to make sense of this claim. In the second chapter, I present my account of iconic reference. In the third chapter, I justify my reliance on a distinction that is less than real yet more than nominal. In the fourth chapter, I sketch a trinitarian metaphysics well-suited to house the foregoing account of qualia. (shrink)

In this thesis I present a new paradigm in human evolutionary theory: the relevance of track-ways reading (TWR) to the evolution of human cognition, culture and communication. Evidence is presented that strongly indicates hominins were exploiting conspecific track-ways 4 million years ago. For a non-olfactory ape that was a specialized forager in open, featureless wetland environments, they were the only viable natural signs to exploit for safety, orienteering, and recognizable social markers. Due to the unique cognitive demands of reading (...) track-ways, as compared to scent-trails all other animals use to find each other and preferred prey species, social TWR triggered the evolution of a unique faculty for narrative elsewhere-and-when cognition in the hominin mind. Two million years later, this narrative faculty was entrenched enough to enable the rather sudden ‘explosion’ of co-operative Oldowan Lithic Culture that began at 2.6mya. This cultural adaptation was a highly successful response to catastrophic environmental change. Thereafter selection for encephalization to increase neural capacity to store and co-operatively exploit socio-ecological knowledge gained from the hominin narrative faculty (via co-evolving, increasingly efficient modes of intentional communication) drove all further biological and cultural developments in the hominin trajectory towards H.sapiens and behavioural modernity.

I defend a theory of mental representation that satisfies naturalistic constraints. Briefly, we begin by distinguishing (i) what makes something a representation from (ii) given that a thing is a representation, what determines what it represents. Representations are states of biological organisms, so we should expect a unified theoretical framework for explaining both what it is to be a representation as well as what it is to be a heart or a kidney. I follow Millikan in explaining (i) in terms (...) of teleofunction, explicated in terms of natural selection. -/- To explain (ii), we begin by recognizing that representational states do not have content, that is, they are neither true nor false except insofar as they both “point to” or “refer” to something, as well as “say” something regarding whatever it is they are about. To distinguish veridical from false representations, there must be a way for these separate aspects to come apart; hence, we explain (ii) by providing independent theories of what I call f-reference and f-predication (the ‘f’ simply connotes ‘fundamental’, to distinguish these things from their natural language counterparts). -/- Causal theories of representation typically founder on error, or on what Fodor has called the disjunction problem. Resemblance or isomorphism theories typically founder on what I’ve called the non-uniqueness problem, which is that isomorphisms and resemblance are practically unconstrained and so representational content cannot be uniquely determined. These traditional problems provide the motivation for my theory, the structural preservation theory, as follows. F-reference, like reference, is a specific, asymmetric relation, as is causation. F-predication, like predication, is a non-specific relation, as predicates typically apply to many things, just as many relational systems can be isomorphic to any given relational system. Putting these observations together, a promising strategy is to explain f-reference via causal history and f-predication via something like isomorphism between relational systems. -/- This dissertation should be conceptualized as having three parts. After motivating and characterizing the problem in chapter 1, the first part is the negative project, where I review and critique Dretske’s, Fodor’s, and Millikan’s theories in chapters 2-4. Second, I construct my theory about the nature of representation in chapter 5 and defend it from objections in chapter 6. In chapters 7-8, which constitute the third and final part, I address the question of how representation is implemented in biological systems. In chapter 7 I argue that single-cell intracortical recordings taken from awake Macaque monkeys performing a cognitive task provide empirical evidence for structural preservation theory, and in chapter 8 I use the empirical results to illustrate, clarify, and refine the theory.

What is the proper metaphysics of quantum mechanics? In this dissertation, I approach the question from three different but related angles. First, I suggest that the quantum state can be understood intrinsically as relations holding among regions in ordinary space-time, from which we can recover the wave function uniquely up to an equivalence class (by representation and uniqueness theorems). The intrinsic account eliminates certain conventional elements (e.g. overall phase) in the representation of the quantum state. It also dispenses with (...) first-order quantification over mathematical objects, which goes some way towards making the quantum world safe for a nominalistic metaphysics suggested in Field (1980, 2016). Second, I argue that the fundamental space of the quantum world is the low-dimensional physical space and not the high-dimensional space isomorphic to the ``configuration space.'' My arguments are based on considerations about dynamics, empirical adequacy, and symmetries of the quantum mechanics. Third, I show that, when we consider quantum mechanics in a time-asymmetric universe (with a large entropy gradient), we obtain new theoretical and conceptual possibilities. In such a model, we can use the low-entropy boundary condition known as the Past Hypothesis (Albert, 2000) to pin down a natural initial quantum state of the universe. However, the universal quantum state is not a pure state but a mixed state, represented by a density matrix that is the normalized projection onto the Past Hypothesis subspace. This particular choice has interesting consequences for Humean supervenience, statistical mechanical probabilities, and theoretical unity. (shrink)

There is no unique and definitive definition of phenomenology. It is rather a method and an experience always open and always renewing itself. Phenomenology involves a change in the "sense of the world": everything acquires its sense and value only when it becomes the content of the lived experience of the subject correlated to his intentional acts. This is the main thesis of the phenomenological method aiming at overcoming the traditional opposition between rationalism and empiricism. Starting from Husserl, the (...) father of this approach, the history of phenomenology undertook different and unexpected developments which in some cases were rather far away from Husserl's original thought. In the U.K. attention has been given to an analytical-epistemological phenomenology focused on the relationship between intentionality and logical semantics. In France it is mainly an anthropological-existential phenomenology. In Germany an hermeneutic phenomenology was developed, mainly by Heidegger and Gadamer. Regardless of these raw distinctions, a big question is so far unresolved: how to reconcile the phenomenological/ existential stance claiming for the irreducibility of each lived experience and the scientific paradigm? Is it possible to imagine brain mechanisms and physiological systems explaining the endless mysteries and manifold paradoxes of the human being? Phenomenology claims that a human being can never be considered as an object, as if he was a natural thing; rather the task is to understand him as the focus of a relationship linking subjective attitudes to the objects showed by the experience. In this sense, an important contribution was Merleau-Ponty's view that man is not something psychic joined to an organism, but a sort of fluctuation of the existence that sometimes is a bodily one, sometimes refers to personal acts. Consequently, he proposes to reinstate in the existence both its "physiological" and "psychic" sides both being intentionally oriented towards a world. (shrink)
