In this paper, I look at Epictetus' dichotomy of control, how it leads to freedom, and how these topics relate to modern life.

An eternal society with the abilities of ordinary humans in each year of its existence would have had the ability to actualize a logical contradiction. This fact casts doubt on the metaphysical possibility of an infinite past. In addition to using this paradox in an argument against an infinite past, one can also use the paradox mutatis mutandis as a decisive argument against the sempiternality of God.

Both professors and institutions of higher education benefit from a vision of academic life that is grounded more firmly in myth than in history. According to the myth created by that traditional vision, scholars pursue research wherever their drive to knowledge takes them, and colleges and universities transmit the fruits of that research to contemporary and future generations as the accumulated wisdom of the ages. Yet the economic and social forces operating on colleges and universities as institutions, as well as (...) on the interests of faculty members within them, are making the myth embodied in the traditional ideal of the academy more and more difficult to sustain. Questions about what an institution of higher education ought to be, about what professors ought to do, and about what relations professors ought to have to the institutions which employ them are being raised and pushed to the fore. These are not theoretical questions, but practical questions of immediate import that must be answered relatively quickly -- and wisely -- if institutions of higher education and professors are not to find themselves inextricably in the grip of forces they cannot change. The myth of disinterested academic research-however beautiful -- and however beneficial -- is under siege. (shrink)

Two controversies exist regarding the appropriate characterization of hierarchical and adaptive evolution in natural populations. In biology, there is the Wright-Fisher controversy over the relative roles of random genetic drift, natural selection, population structure, and interdemic selection in adaptive evolution begun by Sewall Wright and Ronald Aylmer Fisher. There is also the Units of Selection debate, spanning both the biological and the philosophical literature and including the impassioned group-selection debate. Why do these two discourses exist separately, and interact relatively little? (...) We postulate that the reason for this schism can be found in the differing focus of each controversy, a deep difference itself determined by distinct general styles of scientific research guiding each discourse. That is, the Wright-Fisher debate focuses on adaptive process, and tends to be instructed by the mathematical modeling style, while the focus of the Units of Selection controversy is adaptive product, and is typically guided by the function style. The differences between the two discourses can be usefully tracked by examining their interpretations of two contested strategies for theorizing hierarchical selection: horizontal and vertical averaging.

An understanding of the ethical problems that have arisen in the funding of scientific research at universities requires some attention to doctrines that have traditionally been held about science itself. Such doctrines, we hope to show, are themselves central to many of these ethical problems. It is often thought that the questions examined by scientists, and the theories that guide scientific research, are chosen for uniquely scientific reasons, independently of extra-scientific questions of value or merit. We shall argue that this (...) is an illusion. It is an illusion to think, especially in the present era, that science can even have a coherent direction apart from extra-scientific considerations.

Overview of the Stoic position. Looks at the roots of their determinism in their theology, their response to the 'lazy argument' that believing that all things are fated makes action pointless, their analysis of human action and how it allows actions to be 'up to us,' their rejection of the Principle of Alternate Possibilities, their rejection of anger and other negative reactive attitudes, and their contention that submission to god's will brings true freedom.

ABSTRACT Wilfrid Sellars argued that Kant’s account of the conceptual structures involved in experience can be given a linguistic turn so as to provide an analytic account of the resources a language must have in order to be the bearer of empirical knowledge. In this paper I examine the methodological aspects of Kant’s transcendental philosophy that Sellars took to be fundamental to influential themes in his own philosophy. My first aim here is to clarify and argue for the plausibility of (...) what I claim is Sellars’ interpretation of Kant’s ‘analytic’ transcendental method in the first Critique, based ultimately on non-trivial analytic truths concerning the concept of an object of our possible experience. Kant’s ‘transcendental proofs’ thereby avoid a certain methodological trilemma confronting the candidate premises of any such proof, taken from Sellars’ 1970s undergraduate exam question on Kant. In part II of the essay I conclude by highlighting in general terms how Kant’s method, as interpreted in the analytic manner explained in part I, was adapted by Sellars to produce some of the more influential aspects of his own philosophy, expressed in terms of what he contends is their sustainable reformulation in light of the so-called linguistic turn in twentieth-century philosophy.

Abstract: This paper traces a Kantian and pragmatist line of thinking that connects the ideas of conceptual content, object cognition, and modal constraints in the form of counterfactual sustaining causal laws. It is an idea that extends from Kant’s Critique of Pure Reason through C. I. Lewis’s Mind and the World-Order to the Kantian naturalism of Wilfrid Sellars and the analytic pragmatism of Robert Brandom. Kant put forward what I characterize as a modal conception of objectivity, which he developed as (...) an extended argument stretching from the transcendental deduction through the analogies of experience to the regulative maxims of reason and reflective judgment. In related ways in Lewis and Sellars, the very idea of an object of knowledge (and of intentionality more generally) is connected with a certain lawfulness or modal constraint the necessary representation of which, they argue, is an achievement of conceptualization. While Sellars agreed with the spirit of Lewis’s famous pragmatic conception of the a priori, Sellars’s conception of meaning and conceptual content differed in crucial ways with important consequences for this issue. I argue furthermore that a certain phenomenalist temptation threatens to spoil this insight both among some of Kant’s interpreters and in Lewis’s thought. Finally, I point out that Brandom’s “Kant-Sellars thesis” provides new support for this line of thought. Although questions concerning idealism continue to raise controversies for neo-Kantians and pragmatists, the line of thought itself represents a distinctive and still promising approach to questions concerning intentionality and conceptual content.

This chapter argues that the only tenable unconscious inferences theories of cognitive achievement are ones that employ a theory internal technical notion of representation, but that once we give cash-value definitions of the relevant notions of representation and inference, there is little left of the ordinary notion of representation. We suggest that the real value of talk of unconscious inferences lies in (a) their heuristic utility in helping us to make fruitful predictions, such as about illusions, and (b) their providing (...) a high-level description of the functional organization of subpersonal faculties that makes clear how they equip an agent to navigate its environment and pursue its goals.

This article is the preface to a completed book manuscript, United Nations Human Rights Ethics. Based on the indivisibility of human rights, the Four Freedoms Speech, and the Preamble of the Universal Declaration, the book takes freedom of expression as the one human right. Other rights are modes of this one. For example, one exercises freedom of expression (speech) by exercising the right to life, access to courts, etc.. The book argues that human rights are primarily an ethical concept (introduced (...) by Rousseau) rather than a concept of international law. (shrink)

This chapter provides an outline of consent in the history of medical ethics. In doing so, it ranges over attitudes towards consent in medicine in ancient Greece, medieval Europe and the Middle East, as well as the history of Western law and medical ethics from the early modern period onwards. It considers the relationship between consent and both the disclosure of information to patients and the need to indemnify physicians, while attempting to avoid an anachronistic projection of concern with patient (...) autonomy too far back into the historical record. The chapter also includes a survey of the development of the social and intellectual infrastructure that underpins modern medical consent. It concludes with a brief discussion of possible future directions for ethical approaches to medical consent and competence that would depart from the models that arose in the twentieth-century.

The relationship between economics and the philosophy of natural science has changed substantially during the last few years. What was once exclusively a one-way relationship from philosophy to economics now seems to be much closer to bilateral exchange. The purpose of this paper is to examine this new relationship. First, I document the change. Second, I examine the situation within contemporary philosophy of science in order to explain why economics might have its current appeal. Third, I consider some of the (...) issues that might jeopardize the success of this philosophical project. (shrink)

We develop some of Williamson’s ideas regarding how propositional calculus aids in comprehending Aristotelian logic. Specifically, we enhance the utilisation of truth tables to examine the structure of opposition diagrams. Using ‘conditioned truth tables’, we establish logical dependency relationships between the truth values of different propositions. This approach proves effective in interpreting various texts of the Organon concerning the doctrine of opposition.

According to the “standard framing” of racial appeals in political speech, politicians generally rely on coded language to communicate racial messages. Yet recent years have demonstrated that politicians often express quite explicit forms of racism in mainstream political discourse. The standard framing can explain neither why these appeals work politically nor how they work semantically. This paper moves beyond the standard framing, focusing on the politics and semantics of one type of explicit appeal, candid racial communication. The linguistic vehicles of (...) CRC are neither true code words, nor slurs, but a conventionally defined class of “racialized terms.”. (shrink)

ABSTRACT: Sellars once remarked on the “astonishing extent to which in ethics as well as in epistemology and metaphysics the fundamental themes of Kant’s philosophy contain the truth of the variations we now hear on every side” (SM x). Also astonishing was Sellars’ 1970 Presidential Address to the American Philosophical Association (APA), which borrowed its title from the phrase in Kant’s Paralogisms, “...this I or he or it (the thing) which thinks...” (B404). In its compact twenty-five pages Sellars managed to (...) sketch novel yet plausible reconstructions of central aspects of Kant’s views on self-knowledge, persons, freedom, and morality, along the way suggesting how all of those Kantian views could plausibly be rendered consistent with a naturalistic ontology. In this chapter I focus on Sellars’ APA address as an occasion for reflection on how both Kant and Sellars offer insights into how we ought best to conceive the nature of and the relationships between our thinking selves, our practical agency, and our entirely natural, material embodiment.

These comments, which include informal offhand asides made during delivery, derive from an ‘Author Meets Critics’ session on Robert Brandom’s book, From Empiricism to Expressivism: Brandom Reads Sellars’ (2015), held at Kent State University and published subsequently in Sellars and Contemporary Philosophy (2017).

This paper challenges Mäki's argument about commonsensibles by offering a case study from contemporary microeconomics – contemporary revealed preference theory (hereafter CRPT) – where terms like "preference," "utility," and to some extent "choice," are radical departures from the common sense meanings of these terms. Although the argument challenges the claim that economics is inhabited solely by commonsensibles, it is not inconsistent with such folk notions being common in economic theory.

Although epistasis is at the center of the Fisher-Wright debate, biologists not involved in the controversy are often unaware that there are actually two different formal definitions of epistasis. We compare concepts of genetic independence in the two theoretical traditions of evolutionary genetics, population genetics and quantitative genetics, and show how independence of gene action (represented by the multiplicative model of population genetics) can be different from the absence of gene interaction (represented by the linear additive model of quantitative genetics). (...) The two formulations converge with weak selection but not with strong selection or, for multiple loci, when the aggregated interaction terms are not negligible. As a result of the different formulations of gene interaction, the presence or absence of linkage disequilibrium,/D/, does not necessarily indicate the presence or absence of fitness epistasis. Indeed, linkage disequilibrium is generated in ‘additive’ models in quantitative genetics whenever two (or more) loci experience simultaneous selection. As a research strategy, it is often practical, for theoretical or experimental reasons, to minimize gene interaction by assuming independence of gene action in regard to fitness, or by assuming linear additive effects of multiple loci on a phenotype. However, minimizing the role of epistasis in theoretical investigations hinders our understanding of the origins of diversity and the evolution of complex phenotypes. (shrink)

The paper traces the sequence of events which brought Popperian philosophy (including Lakatos) to its position on the issues of excess content, novelty and scientific progress. The general approach is to analyze Popper's and Lakatos's positions on these issues as an appropriate response to a particular philosophical problem situation in which they found themselves. The paper closes with a discussion of how these issues relate to economics and economic methodology.

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

In this editorial, we argue that midwives should focus on climate change, a link which has been underexplored.

It is tempting to think that one’s perceptual evidence comprises just what issues from perceiving with each of the respective sensory modalities. However, empirical, rational, and phenomenological considerations show that one’s perceptual evidence can outstrip what one possesses due to perceiving with each separate sense. Some novel perceptual evidence stems from the coordinated use of multiple senses. This paper argues that some perceptual evidence in this respect is distinctively multisensory.

Economic liberty is best understood in opposition to economic domination. This article develops a radical republican conception of such domination. In particular, I argue that radical republicanism provides a more satisfactory account of individual economic freedom than the market-friendly liberties of working, transacting, holding, and using championed by Nickel and Tomasi. So too, it avoids the pitfalls of other conceptions of economic liberty which emphasize real freedom, alternatives to immiserating work, or unalienated labor. The resulting theory holds that economic domination (...) occurs when someone’s access to civic capabilities is contingent on the arbitrary economic power of others. Socialist institutions—suitably configured—can deliver on this individual economic freedom, allowing the dominating power of proprietors, shareholders, landlords, and managers to be kept in check, and providing an unconditional minimum that allows individual citizens to be less beholden to others in meeting many of their most fundamental civic needs. Thus, I conclude that socialism can be championed as a politics of individual economic liberty. (shrink)

Recent scholarship in intellectual humility (IH) has attempted to provide deeper understanding of the virtue as personality trait and its impact on an individual's thoughts, beliefs, and actions. A limitations-owning perspective of IH focuses on a proper recognition of the impact of intellectual limitations and a motivation to overcome them, placing it as the mean between intellectual arrogance and intellectual servility. We developed the Limitations-Owning Intellectual Humility Scale to assess this conception of IH with related personality constructs. In Studies 1 (...) (n= 386) and 2 (n = 296), principal factor and confirmatory factor analyses revealed a three-factor model – owning one's intellectual limitations, appropriate discomfort with intellectual limitations, and love of learning. Study 3 (n = 322) demonstrated strong test-retest reliability of the measure over 5 months, while Study 4 (n = 612) revealed limitations-owning IH correlated negatively with dogmatism, closed-mindedness, and hubristic pride and positively with openness, assertiveness, authentic pride. It also predicted openness and closed-mindedness over and above education, social desirability, and other measures of IH. The limitations-owning understanding of IH and scale allow for a more nuanced, spectrum interpretation and measurement of the virtue, which directs future study inside and outside of psychology.

Review Article on Mirowski's More Heat Than Light (1989).

Abstract: This paper examines Mark Blaug's position on the normative character of Paretian welfare economics: in general, and specifically with respect to his debate with Pieter Hennipman over this question during the 1990s. The paper also clarifies some of the confusions that emerged within the context of this debate, and closes by providing some additional arguments supporting Blaug's position that he himself did not provide.

Abstract: The paper argues that mainstream economics and mainstream philosophy of natural science had much in common during the period 1945-1965. It examines seven common features of the two fields and suggests a number of historical developments that might help explain these similarities. The historical developments include: the Vienna Circle connection, the Samuelson-Harvard-Foundations connection, and the Cold War operations research connection.

Central to Sellars’ account of human cognition was a clear distinction, expressed in varying terminology in his different works, “between conceptual and nonconceptual representations.” Those who have come to be known as ‘left-wing Sellarsians’, such as Richard Rorty, Robert Brandom, and John McDowell, have tended to reject Sellars’ appeals to nonconceptual sensory representations. So-called ‘right-wing Sellarsians’ such as Ruth Millikan and Jay Rosenberg, on the other hand, have embraced and developed aspects of Sellars’ account, in particular the central underlying idea (...) that human perceptual cognition involves a certain naturalistic ‘mapping’ correspondence or structural ‘picturing’ isomorphism between internal mental representations and the layout and behavior of objects in the surrounding environment. Sellars, despite his defenses of nonconceptual representational content throughout his career, has with no small irony come to be cited as one of the “founding fathers of conceptualism.” While recognizing the strong conceptualist elements in Sellars’ Kantian account of perceptual cognition, I argue that a central core of Sellars’ account of nonconceptual sensory contents does not by itself fall afoul of the philosophical worries raised by the left-leaning Sellarsians, and that in fact it has significant merits in its own right.

Abstract: Don Ross’ Economic Theory and Cognitive Science (2005) provides an elaborate philosophical defense of neoclassical economics. He argues that the central features of neoclassical theory are associated with what he calls the Robbins-Samuelson argument pattern and that it can be reconciled with recent developments in experimental and behavioral economics, as well as contemporary cognitive science. This paper argues that Ross’ Robbins-Samuelson argument pattern is not in the work of either Robbins or Samuelson and in many ways is in conflict (...) with their own versions, and defenses, of neoclassical theory.

Appeals to nature are ubiquitous in Epicurean ethics and politics. The foundation of Epicurean ethics is its claim that pleasure is the sole intrinsic good and pain the sole intrinsic evil, and this is supposedly shown by the behavior of infants who have not yet been corrupted, "when nature's judgement is pure and whole." Central to their recommendations about how to attain pleasure is their division between types of desires: the natural and necessary ones, the natural but non-necessary ones, and (...) the vain and empty ones. Elsewhere, the Epicureans talk about the "natural goods" of political power and fame, and they contrast "natural wealth" with wealth as "defined by empty opinion." Finally, in their politics, Epicurus claims that the "the justice of nature is a pledge of reciprocal usefulness, [i.e.,] neither to harm one another nor to be harmed." This paper explores two questions regarding these various appeals to nature. The first is: what is it for these things to be natural, i.e., what notion of "natural" or "nature" is at play here? (Furthermore, is there a single notion being used across these appeals, and if not, how are they related?) The second is: what normative work does a thing's being natural do? That is, what reason, if any, does a desire's being natural give me for pursuing the object of that desire and trying to fulfill that desire, as opposed to not doing so and trying to eliminate it, and similarly for the other appeals to nature?

Anaxarchus accompanied Pyrrho on Alexander the Great’s expedition to India and was known as “the Happy Man” because of his impassivity and contentment. Our sources on his philosophy are limited and largely consist of anecdotes about his interactions with Pyrrho and Alexander, but they allow us to reconstruct a distinctive ethical position. It overlaps with several disparate ethical traditions but is not merely a hodge-podge; it hangs together as a unified whole. Like Pyrrho, he asserts that things are indifferent in (...) value and that realizing this indifference leads to contentment. But this doctrine of indifference is rooted in Democritean atomism. And in his pursuit of pleasure and dismissiveness of conventional standards of what is just, noble, and pious, Anaxarchus is closer to fifth century thinkers such as Aristippus, Antiphon, and Critias.

This article addresses two areas of continuing controversy about consent in clinical research: the question of when consent to low risk research is necessary, and the question of when consent to research is valid. The article identifies a number of considerations relevant to determining whether consent is necessary, chief of which is whether the study would involve subjects in ways that would (otherwise) infringe their rights. When consent is necessary, there is a further question of under what conditions consent is (...) valid or successful in waiving a right. The most influential account of validity conditions is non-moralized, in the sense that the conditions make no essential reference to whether the researcher soliciting consent has obtained it in a way that wrongs the subject. The article examines the implications of this account, and compares it with recent accounts that moralize some of the validity conditions. -/- . (shrink)

Harrison Frye claims that socialist republicanism may be unable to reduce domination due to efficiency costs and accountability deficits imposed by public ownership. I argue that the empirical and theoretical grounds for expecting such a decline in economic efficiency are weak. Moreover, the egalitarian distributive effects of public ownership are likely to be more important for insulating people from domination. So too, workers, consumers, and citizens are not well-protected from domination by the accountability of managers to profit-seeking shareholders. I conclude (...) that the investor-owned firm will do far more to exacerbate dominating power than to constrain it. (shrink)

The norms of simplicity, convenience, unfussiness, and self-control guide Diogenes the Cynic, Zeno of Citium, Chrysippus, Seneca, Musonius Rufus, Epictetus, and Marcus Aurelius in approaching food. These norms generate the precept that meat and dainties are luxuries, so Stoics should eschew them. Considerations of justice, environmental harm, anthropogenic global climate change, sustainability, food security, feminism, harm to animals, personal health, and public health lead contemporary Stoics to condemn the meat industrial complex, debunk carnism, and select low input, plant-based foods.

ABSTRACT: It is a familiar story that Kant’s defence of our synthetic a priori cognition in the Critique of Pure Reason suffered sharp criticism throughout the extended philosophical revolutions that established analytic philosophy, the pragmatist tradition, and the phenomenological tradition as dominant philosophical movements in the first half of the twentieth century. One of the most important positive adaptations of Kant’s outlook, however, was the combined analytic and pragmatist conceptions of the a priori that were developed by the American philosophers (...) C. I. Lewis (1883–1964) and Wilfrid Sellars (1912–1989), most notably in Lewis’s 1929 classic, Mind and the World Order, followed by Sellars’ critical reworking of Lewis’s outlook in ‘Is There a Synthetic A Priori?’ (1953) and other mid-century articles. Both Lewis and Sellars defended central aspects of Kant’s analysis of our a priori knowledge of mind-independent physical objects and necessary causal connections. But both also radically transformed Kant’s view by defending the idea that there are alternative a priori conceptual frameworks that are subject to an ongoing process of reassessment and replacement on overall pragmatic and explanatory grounds. Furthermore, while Sellars’ answer to his question, ‘Is There a Synthetic A Priori?’ thus represented a partial endorsement of Lewis’s pragmatic relativization of the a priori, I argue that Sellars’ account of meaning diverged from Lewis in ways that constituted a significant improvement upon the previous ‘analytic’ defenses of the a priori, not only in Lewis but in general. This arguably has implications for wider disputes concerning the nature and possibility of a priori knowledge in non-formal domains. (shrink)

In Outlines of Pyrrhonism, Sextus Empiricus takes pains to differentiate the skeptical way of life from other positions with which it is often confused, and in the course of this discussion he briefly explains how skepticism differs from Cyrenaicism. Surprisingly, Sextus does not mention an important apparent difference between the two. The Cyrenaics have a positive epistemic commitment--that we can apprehend our own affections. Although we cannot know whether the honey is really sweet, we can know infallibly that right now (...) we are being sweetened. By contrast, Sextus says explicitly that, as skeptics, Pyrrhonists apprehend nothing whatsoever. A case can (and has) been made that Sextus does not mention this difference because, on this matter, there really isn't an important difference between the two: the skeptic is perfectly able to report how things appear to him, e.g., that the honey seems sweet, and it is crucial for the skeptic that he not abolish the appearances. But, I argue, what the skeptics are doing when they report how things appear to them is importantly different from the sort of immediate, infallible apprehension of one's own affections claimed by the Cyrenaics, as the latter involves theoretical commitments regarding the nature of one's affections that the skeptic eschews.

ABSTRACT: I contend that Sellars defends a uniquely Kantian naturalist outlook both in general and more particularly in relation to the nature and status of what he calls ‘epistemic principles’; and I attempt to show that this remains a plausible and distinctive position even when detached from Sellars’s quasi-Kantian transcendental idealist contention that the perceptible objects of the manifest image strictly speaking do not exist, i.e., as conceived within that common sense framework. I first explain the complex Kant-inspired sense in (...) which Sellars did not take the latter thesis concerning the objects of the manifest image to apply, at least in certain fundamental respects, to persons. In this primary Kantian sense, I suggest, persons as thinkers and agents exist univocally across both the manifest and scientific images, and this in principle would enable an integration of persons within a multi-leveled naturalistic ontology, one that is independent of Sellars’s quasi-Kantian transcendental idealist thesis. Finally, I examine in some detail how this defensible blend of Kantian and naturalist themes turns out to be what is fundamental in Sellars’s complex and controversial views on the nature and status of epistemic principles.

The first part of this paper looks into the question of Lucretius’ philosophical sources and whether he draws almost exclusively from Epicurus himself or also from later Epicurean texts. I argue that such debates are inconclusive and likely will remain so, even if additional Epicurean texts are discovered, and that even if we were able to ascertain Lucretius’ philosophical sources, doing so would add little to our understanding of the De Rerum Natura. The second part of the paper turns to (...) a consideration of what Lucretius does with his philosophical sources. The arguments within the De Rerum Natura are not original. Nonetheless, the way Lucretius presents these arguments establishes him as a distinctive philosopher. Lucretius deploys non-argumentative methods of persuasion such as appealing to emotions, redeploying powerful cultural tropes, and ridicule. These methods of persuasion do not undercut or displace reasoned argumentation. Instead, they complement it. Lucretius’ use of these methods is rooted in his understanding of human psychology, that we have been culturally conditioned to have empty desires, false beliefs, and destructive emotions, ones that are often subconscious. Effective persuasion must take into account the biases, stereotypes, and other psychological factors that hinder people from accepting Epicurus’ healing gospel. (shrink)

This paper focuses on two questions: (I) why do the Cyrenaics deny that we can gain knowledge concerning "external things," and (II) how wide-ranging is this denial? On the first question, I argue that the Cyrenaics are skeptical because of their contrast between the indubitable grasp we have of own affections, versus the inaccessibility of external things that cause these affections. Furthermore, this inaccessibility is due to our cognitive and perceptual limitations--it is an epistemological doctrine rooted in their psychology--and not (...) (pace Zilioli) due to any metaphysical theses regarding the external world. On the second question, I argue (pace Tsouna and Warren) that the scope of the Cyrenaics' skepticism is quite wide. Our reports on the Cyrenaics are inconsistent, but the most charitable and plausible reading results in attributing to the Cyrenaics skepticism not merely about the properties of external things (e.g., that the fire that warms me is really hot) of also of their nature and identity (e.g., that the object that warms me is a fire). However, it does not extend to skepticism regarding the existence of an external world. (shrink)
