"All political action has . . . in itself a directedness towards knowledge of the good: of the good life, or of the good society. For the good society is the complete political good. If this directedness becomes explicit, if men make it their explicit goal to acquire knowledge of the good life and of the good society, political philosophy emerges. . . . The theme of political philosophy is mankind's great objectives, freedom and government or empire--objectives which are capable (...) of lifting all men beyond their poor selves. Political philosophy is that branch of philosophy which is closest to political life, to non-philosophic life, to human life."--From "What Is Political Philosophy?" What Is Political Philosophy? --a collection of ten essays and lectures and sixteen book reviews written between 1943 and 1957--contains some of Leo Strauss's most famous writings and some of his most explicit statements of the themes that made him famous. The title essay records Strauss's sole extended articulation of the meaning of political philosophy itself. Other essays discuss the relation of political philosophy to history, give an account of the political philosophy of the non-Christian Middle Ages and of classic European modernity, and present his theory of esoteric writing.

""Catching Ourselves in the Act" is no less than an attempt to explain intelligence. Delightful how the author dismantles traditional views in.

Jennifer Lackey (2018) has developed an account of the primary form of group assertion, according to which groups assert when a suitably authorized spokesperson speaks for the group. In this paper I pose a challenge for Lackey's account, arguing that her account obscures the phenomenon of group silencing. This is because, in contrast to alternative approaches that view assertions (and speech acts generally) as social acts, Lackey's account implies that speakers can successfully assert regardless of how their utterances are taken (...) up by their audiences. What reflection on group silencing shows us, I argue, is that an adequate account of group assertion needs to find a place for audience uptake. (shrink)

According Philip Pettit, suitably organised groups not only possess ‘minds of their own’ but can also ‘make up their minds’ and 'speak for themselves'--where these two capacities enable them to perform as conversable subjects or 'persons'. In this paper I critically examine Pettit's case for group personhood. My first step is to reconstruct his account, explaining first how he understands the two capacities he considers central to personhood – the capacity to ‘make up one’s mind’, and the capacity to ‘speak (...) for oneself’ – before showing how he thinks these can be manifested in groups. With Pettit’s account duly reconstructed, I then turn to criticism, arguing that Pettit’s construal of making up one’s mind does not do proper justice to our first-personal self-understanding, nor to our characteristic interpersonal forms of engagement. This leads me, finally, to consider an alternative construal of ‘making up one’s mind’ and ‘speaking for oneself’ that is associated with the work of Richard Moran and whichargue, could usefully be exteextended to groups.

In the present article two possible meanings of the term mathematical structure are discussed: a formal and a nonformal one. It is claimed that contemporary mathematics is structural only in the nonformal sense of the term. Bourbaki's definition of structure is presented as one among several attempts to elucidate the meaning of that nonformal idea by developing a formal theory which allegedly accounts for it. It is shown that Bourbaki's concept of structure was, from a mathematical point of view, a (...) superfluous undertaking. This is done by analyzing the role played by the concept, in the first place, within Bourbaki's own mathematical output. Likewise, the interaction between Bourbaki's work and the first stages of category theory is analyzed, on the basis of both published texts and personal documents. (shrink)

This article explores the changing relationships between geometric and arithmetic ideas in medieval Europe mathematics, as reflected via the propositions of Book II of Euclid’s Elements. Of particular interest is the way in which some medieval treatises organically incorporated into the body of arithmetic results that were formulated in Book II and originally conceived in a purely geometric context. Eventually, in the Campanus version of the Elements these results were reincorporated into the arithmetic books of the Euclidean treatise. Thus, while (...) most of the Latin versions of the Elements had duly preserved the purely geometric spirit of Euclid’s original, the specific text that played the most prominent role in the initial passage of the Elements from manuscript to print—i.e., Campanus’ version—followed a different approach. On the one hand, Book II itself continued to appear there as a purely geometric text. On the other hand, the first ten results of Book II could now be seen also as possiblytranslatable into arithmetic, and in many cases even as inseparably associated with their arithmetic representation.

Unrealistic optimism is a bias that leads people to believe, with respect to a specific event or hazard, that they are more likely to experience positive outcomes and/or less likely to experience negative outcomes than similar others. The phenomenon has been seen in a range of health-related contexts—including when prospective participants are presented with the risks and benefits of participating in a clinical trial. In order to test for the prevalence of unrealistic optimism among participants of early-phase oncology trials, we (...) conducted a survey with patients over 18 years of age who were enrolled in a phase I, phase I/II, or phase II clinical cancer trial in the New York City area between August 2008 and October 2009. Participants in our study were asked to compare their own chances of experiencing a range of risks and benefits related to the trial they were enrolled in with the chances of the other trial participants. We found a significant optimistic bias in their responses. Respondents tended to overestimate the benefits of the trial they were enrolled in and underestimate its risks. In addition, we found no significant relationship between respondents’ understanding of the trial’s purpose and how susceptible they were to unrealistic optimism. Our findings suggest that improving the consent process for oncology studies requires more than addressing deficits in understanding. (shrink)

In the pioneering article and two papers, written jointly with McKinsey, Tarski developed the so-called algebraic and topological frameworks for the Intuitionistic Logic and the Lewis modal system. In this paper, we present an outline of modern systems with a topological tinge. We consider topological interpretation of basic systems GL and G of the provability logic in terms of the Cantor derivative and the Hausdorff residue.

In this paper I trace Husserl’s transformation of his notion of phantasy from its strong leanings towards empiricism into a transcendental phenomenology of imagination. Rejecting the view that this account is only more incompatible with contemporary neuroscientific research, I instead claim that the transcendental suspension of naturalistic (or scientific) pretensions precisely enables cooperation between the two distinct realms of phenomenology and science. In particular, a transcendental account of phantasy can disclose the specific accomplishments of imagination without prematurely deciding upon a (...) particular scientific paradigm for its experimental investigation; a decision that is best left to the sciences themselves.

It is often claimed that the intentions of physicians are multiple, ambiguous, and uncertain—at least with respect to end-of-life care. This claim provides support for the conclusion that the principle of double effect is of little or no value as a guide to end-of-life pain management. This paper critically discusses this claim. It argues that proponents of the claim fail to distinguish two different senses of “intention,” and that, as a result, they are led to exaggerate the extent to which (...) clinical intentions in end-of-life contexts are ambiguous and uncertain. It argues further that physicians, like others who make life and death decisions, have a duty to get clear on what their intentions are. Finally, it argues that even if the principle of double effect should be rejected, clinical intentions remain ethically significant because they condition the meaning of extraordinary clinical interventions, such as that of palliative sedation.

In order to develop the ontology of tendencies for use in the representation of medical knowledge, tendencies are compared with other kinds of entities possessing the realizable-realization structure, specifically: dispositions, propensities, abilities and virtues. The peculiarities of tendencies are discussed and a standard schema of tendency ascription is developed in order to represent the relations between the ascriptions of tendency tokens to particulars and the ascriptions of tendency types to universals. Two nonstandard cases and their epistemic variants are discussed.

Recent years have witnessed a growing concern that terminally illpatients are needlessly suffering in the dying process. This has ledto demands that physicians become more attentive in the assessment ofsuffering and that they treat their patients as `whole persons.'' Forthe most part, these demands have not fallen on deaf ears. It is nowwidely accepted that the relief of suffering is one of the fundamentalgoals of medicine. Without question this is a positive development.However, while the importance of treating suffering has generally (...) beenacknowledged, insufficient attention has been paid to the question ofwhether different types of terminal suffering require differnt responsesfrom health care professionals. In this paper we introduce a distinctionbetween two types of suffering likely to be present at the end of life,and we argue that physicians must distinguish between these types if theyare to respond appropriately to the suffering of their terminally illpatients. After introducing this distinction and explaining its basis,we further argue that the distinction informs a (novel) principle ofproportionality, one that should guide physicians in balancing theircompeting obligations in responding to terminal suffering. As weexplain, this principle is justified by reference to the intereststerminally ill patients have in restoration, as well as in therelief of suffering, at the end of life. (shrink)

In this paper, we defend the ethics of clinical research against the charge of paternalism. We do so not by denying that the ethics of clinical research is paternalistic, but rather by defending the legitimacy of paternalism in this context. Our aim is not to defend any particular set of paternalistic restrictions, but rather to make a general case for the permissibility of paternalistic restrictions in this context. Specifically, we argue that there is no basic liberty-right to participate in clinical (...) research and that considerations of distributive fairness justify some paternalistic protections of research subjects.

Is a bank note identical with the piece of paper of which it consists? On the one hand, John Searle, in his reply to Barry Smith, suggests that they are “one and the same object” that is a social or non-social object only under certain descriptions. On the other hand, Lynne Rudder Baker puts forward the claim that bank note and paper are distinct entities that are bound together by the relation of material constitution. I suggest two possible analyses for (...) Searle’s description relativity claim, the Alternative Subject Analysis and the Predicate Modification Analysis. On both accounts his identity claim gets into serious trouble. While Baker’s definition of material constitution deals well with the bank note example, it fails to account for the constitution of bearerless social entities and groups. I point out five respects in which social constitution can differ from Baker’s account of material constitution and discuss compositional, institutional and interactional constitution as additional varieties of social constitution.

Being an "untimely review", this paper reviews Aristotle's 'Categories' as if they were published today, in the era of computerised information, where categorisation becomes more and more essential for information retrieval. I suggest a systematic ordering of Aristotle's list of categories and argue that Aristotle's discussion of ontological dependency and his focus on concrete entities are still a source of new insight and can indeed be read as a contribution to the emerging field of applied ontology and ontological engineering.

The term “exploitation” has gained wide currency in recent discussions of biomedical and research ethics. This is due in no small measure to the influence of Alan Wertheimer’s path-breaking work on the topic (Wertheimer 1999, 2011). Wertheimer presented a clear and compelling non-Marxist account of the concept of exploitation—one that stressed the connection between exploitation and unfair distributive outcomes. On this account, when one party exploits another, she takes advantage of the other to gain unfairly. A number of contemporary bioethicists (...) have accepted Wertheimer’s account of exploitation and have proceeded to apply it to a range of issues in research ethics (Hawkins and Emanuel 2008; Miller and Brody ..

Margaret Gilbert has defended the claim that her plural subject theory can give a reasonable account of retrospective (or backward-looking) collective responsibility. On one occasion, publishing in this periodical, she writes that she deliberately left out the discussion of prospective (or forward-looking) collective responsibility, or the “responsibilities” of a collective. In the present paper, I want to show that plural subject theory, in fact, also allows accounting for prospective responsibilities of groups and institutions. In order to do so, I will (...) first sketch the social ontological background of my discussion which is, in fact, an amended version of Gilbert’s theory of plural subjects (§ 2). Based on the assumption that a prospective responsibility accrues from some kind of commissioning, I will then discuss a variety of possible sources of prospective collective responsibilities: self-commissioning, third-party commissioning and what I will call commissioning by unique capability (§ 3). Having done so, I will discuss some consequences of this account and defend it against objections (§ 4). (shrink)

The movement in bioethics toward disclosure of financial conflicts of interest is well and good, most of the time. But in some cases, disclosure is not only unnecessary but destructive. When bioethicists advance arguments whose premises and logical moves are open to scrutiny, disclosure—far from clearing the air of bias—introduces bias.

In this paper, I draw from Kantian and Husserlian reflections on the self-awareness of thinking for a contribution to the cognitive phenomenology debate. In particular, I draw from Kant’s conceptions of inner sense and apperception, and from Husserl’s notions of lived experience and self-awareness for an inquiry into the nature of our awareness of our own cognitive activity. With particular consideration of activities of attention, I develop what I take to be Kant’s and Husserl’s “agentive” and “proprietary” accounts. These, I (...) believe, augment contemporary discussions in interesting ways and further bolster the case for cognitive phenomenology. Moreover, the historical comparison highlights a number of assumptions made today that were not yet part of the framework at the time of Kant or at the time of Husserl. This helps reflect on the legitimacy of these assumptions. (shrink)

It has long been a standard practice for the natural sciences to classify things. Thus, it is no wonder that, for two and a half millennia, philosophers have been reflecting on classifications, from Plato and Aristotle to contemporary philosophy of science. Some of the results of these reflections will be presented in this chapter. I will start by discussing a parody of a classification, namely: the purportedly ancient Chinese classification of animals described by Jorge Luis Borges. I will show that (...) many of the mistakes that account for the comic features of this parody appear in real-life scientific databases as well. As examples of the latter, I will discuss the terminology database of the National Cancer Institute (NCI) of the United States, the NCI Thesaurus. (shrink)

In an era of rapidly rising health care costs, physicians and policymakers are searching for new and effective ways to contain health care spending without sacrificing the quality of services provided. These proposals are increasingly articulated in terms of an ethical duty of stewardship. The duty of stewardship in medicine, however, is not at present well understood, and it is frequently conflated with other duties. This article presents a critical analysis of the notion of stewardship, which shows that it has (...) an important and distinctive place in medical ethics. It claims that stewardship in medicine concerns the responsible use of a society’s medical resources and it discusses the extent to which medical professionals are the proper stewards of these resources. The article argues that the duty of stewardship is best understood as a duty that applies in a space between the obligations of health care providers to provide beneficent care to their patients on the one hand and the obligations of citizens to bring about and support a just health care system on the other. Seen with clear eyes, stewardship in medicine is neither a consequence of beneficent medical care nor a substitute for justice. (shrink)

Throughout the long centuries of western metaphysics the problem of the infinite has kept surfacing in different but important ways. It had confronted Greek philosophical speculation from earliest times. It appeared in the definition of the divine attributed to Thales in Diogenes Laertius (I, 36) under the description "that which has neither beginning nor end. " It was presented on the scroll of Anaximander with enough precision to allow doxographers to transmit it in the technical terminology of the unlimited (apeiron) (...) and the indeterminate (aoriston). The respective quanti tative and qualitative implications of these terms could hardly avoid causing trouble. The formation of the words, moreover, was clearly negative or privative in bearing. Yet in the philosophical framework the notion in its earliest use meant something highly positive, signifying fruitful content for the first principle of all the things that have positive status in the universe. These tensions could not help but make themselves felt through the course of later Greek thought. In one extreme the notion of the infinite was refined in a way that left it appropriated to the Aristotelian category of quantity. In Aristotle (Phys. III 6-8) it came to appear as essentially re quiring imperfection and lack. It meant the capacity for never-ending increase. It was always potential, never completely actualized. (shrink)

Used informally, the Reductio ad Absurdum (RAA) consists in reasoning appealing to the logically implied, absurd consequences of a hypothetical proposition, in order to refute it. This kind of reasoning resembles the Argument from Consequences, which appeals to causally induced consequences. These types of argument are sometimes confused, since it is not worked out how these different kinds of consequences should be distinguished. In this article it is argued that the logical consequences in RAA-argumentation can take different appearances and that (...) it therefore must be concluded that RAA cannot be characterised by a specific content, but must instead be characterised as an argument form. Furthermore, clues are provided to distinguish RAA reasoning from the Argument from Consequences. (shrink)

Article Title: ‘Being and Becoming in the Theory of Group Agency’This paper explores a bootstrapping puzzle which appears to afflict Philip Pettit’s theory of group agency. Pettit claims that the corporate persons recognised by his theory come about when a set of individuals ‘gets its act together’ by undertaking to reason at the collective level. But this is puzzling, because it is hard to see how the step such a collective must take to become a group agent – the collectivisation (...) of reason – can be taken without them already being an agent. I explore this puzzle by recounting Pettit’s account of the emergence of group agents. According to Pettit this process has two stages: a first stage in which a collective incurs the distinctive pressure exemplified by the Doctrinal Paradox, and a second in which the collective responds to that pressure by instituting decision-making mechanisms designed to secure collective rationality. After arguing that this second, response stage in Pettit’s account is not coherent, I conclude with the tentative suggestion that the personhood of groups should be seen as depending not only on the efforts of group members but also on the recognitive attitudes of other persons in a wider discursive community.

Some commentators have recently proposed that “clinical equipoise,” although widely accepted, is not necessary for morally acceptable research on human subjects. If this concept is rejected, however, we may find that trials not in the best medical interests of their subjects—”bad deal trials”—could be justified. To avoid exploiting participants, we must find a way to distribute the risks fairly, even if it means embracing radical changes in the way clinical research is conducted.
