According to the traditional Bayesian view of credence, its structure is that of precise probability, its objects are descriptive propositions about the empirical world, and its dynamics are given by conditionalization. Each of the three essays that make up this thesis deals with a different variation on this traditional picture. The first variation replaces precise probability with sets of probabilities. The resulting imprecise Bayesianism is sometimes motivated on the grounds that our beliefs should not be more precise than the evidence (...) calls for. One known problem for this evidentially motivated imprecise view is that in certain cases, our imprecise credence in a particular proposition will remain the same no matter how much evidence we receive. In the first essay I argue that the problem is much more general than has been appreciated so far, and that it’s difficult to avoid without compromising the initial evidentialist motivation. The second variation replaces descriptive claims with moral claims as the objects of credence. I consider three standard arguments for probabilism with respect to descriptive uncertainty—representation theorem arguments, Dutch book arguments, and accuracy arguments—in order to examine whether such arguments can also be used to establish probabilism with respect to moral uncertainty. In the second essay, I argue that by and large they can, with some caveats. First, I don’t examine whether these arguments can be given sound non-cognitivist readings, and any conclusions therefore only hold conditional on cognitivism. Second, decision-theoretic representation theorems are found to be less convincing in the moral case, because there they implausibly commit us to thinking that intertheoretic comparisons of value are always possible. Third and finally, certain considerations may lead one to think that imprecise probabilism provides a more plausible model of moral epistemology. The third variation considers whether, in addition to conditionalization, agents may also change their minds by becoming aware of propositions they had not previously entertained, and therefore not previously assigned any probability. More specifically, I argue that if we wish to make room for reflective equilibrium in a probabilistic moral epistemology, we must allow for awareness growth. In the third essay, I sketch the outline of such a Bayesian account of reflective equilibrium. Given that this account gives a central place to awareness growth, and that the rationality constraints on belief change by awareness growth are much weaker than those on belief change by conditionalization, it follows that the rationality constraints on the credences of agents who are seeking reflective equilibrium are correspondingly weaker.

In our everyday discourse, most of us use modal statements to express possibility, necessity, or contingency. Logicians, linguists, and philosophers of language tend to use the possible world discourse to analyse the semantics of this kind of sentences. There is a disadvantage of this method: in the usual Quinean meta-ontology it commits the users to the existence of possible worlds. Even though there are many theories on metaphysics of these possible worlds, I will focus on the fictionalist approach, which aims (...) to suspend the undesired ontological commitment. Therefore it is an anti-realist theory. The fictionalist strategy is based on the idea that according to our common-sense ontology, fictions and fictional entities do not exist, and one can treat the possible world discourse as a fiction, and the possible worlds as fictional entities. However, in the last two decades, realist theories about fictions and fictional entities have arisen, especially the abstract artefact theory. In this paper I try to revise the fictionalist approach to modality by keeping the main idea that possible worlds are fictional entities, while accepting that fictional entities are abstract artefacts. The result is a new realist theory of modal fictionalism. (shrink)

Suppose that an altruistic agent who is uncertain between evidential and causal decision theory finds herself in a situation where these theories give conflicting verdicts. We argue that even if she has significantly higher credence in CDT, she should nevertheless act in accordance with EDT. First, we claim that the appropriate response to normative uncertainty is to hedge one's bets. That is, if the stakes are much higher on one theory than another, and the credences you assign to each of (...) these theories are not very different, then it is appropriate to choose the option that performs best on the high-stakes theory. Second, we show that, given the assumption of altruism, the existence of correlated decision makers will increase the stakes for EDT but leave the stakes for CDT unaffected. Together these two claims imply that whenever there are sufficiently many correlated agents, the appropriate response is to act in accordance with EDT. (shrink)

Leo Strauss’ controversial theory of esoteric philosophy, as presented in Persecution and the Art of Writing, sparked a fierce debate. Opponents and proponents of the theory utilised a wide range of perspectives to support their arguments. By investigating esoteric philosophy from a sociolinguistic perspective, this paper introduces a novel perspective to the Strauss dispute. In PAW Strauss is mistaken regarding esotericism and its role in philosophy. On one hand it is reasonable to endorse Strauss’ persuasive account on the origins of (...) esoteric writing. The Straussian account provides a plausible sociological background as to why philosophy, per se became an esoteric fliedH. On the other hand it seems as Strauss ascribed undue significance to possible clandestine massages that may be found within works of philosophy because philosophy is mostly already done in an esoteric linguistic space.

Considering the short history of the feminist philosophy of language, Rae Langton’s article “Speech Acts and Unspeakable Acts” was highly influential as one of the first positive research programs in the movement. In that paper, Langton – using John L. Austin’s speech act theory – tries to interpret Catharine MacKinnon’s thesis: pornography is a speech that subordinates and silences women. Despite the importance of the subject, those unfamiliar with certain historical and contextual features of the topic would hardly understand it. (...) My paper aims to introduce some of the major accounts in this special area in the intersection of speech act theory and feminist philosophy. Rather than just reconstructing Langton’s arguments and the most common objections against it, I will take a more holistic approach, examining its surrounding literature as well. This article has six sections. In Section 1, I contrast the conservative and liberal arguments against pornography and sketch MacKinnon’s liberal critique. In Section 2, I give alternative interpretations of MacKinnon’s thesis, “pornography is harm.” In Section 3, I try to make sense of the prima facie implausible assumption that pornography is speech. In Section 4 and 5, I will analyze the Langtonian theories about subordination and silencing. Finally, in Section 6, I will mention the most challenging problems for Langton’s approach, considering the verbal nature or pornography, the limits of the protection of free speech, and the different positions on sexual consent.

Traditional Bayesianism requires that an agent’s degrees of belief be represented by a real-valued, probabilistic credence function. However, in many cases it seems that our evidence is not rich enough to warrant such precision. In light of this, some have proposed that we instead represent an agent’s degrees of belief as a set of credence functions. This way, we can respect the evidence by requiring that the set, often called the agent’s credal state, includes all credence functions that are in (...) some sense compatible with the evidence. One known problem for this evidentially motivated imprecise view is that in certain cases, our imprecise credence in a particular proposition will remain the same no matter how much evidence we receive. In this article I argue that the problem is much more general than has been appreciated so far, and that it’s difficult to avoid it without compromising the initial evidentialist motivation. _1_ Introduction _2_ Precision and Its Problems _3_ Imprecise Bayesianism and Respecting Ambiguous Evidence _4_ Local Belief Inertia _5_ From Local to Global Belief Inertia _6_ Responding to Global Belief Inertia _7_ Conclusion.

Autonomous Weapons Systems (AWS) have not gained a good reputation in the past. This attitude is odd if we look at the discussion of other-usually highly anticipated-AI-technologies, like autonomous vehicles (AVs); whereby even though these machines evoke very similar ethical issues, philosophers' attitudes towards them are constructive. In this article, I try to prove that there is an unjust bias against AWS because almost every argument against them is effective against AVs too. I start with the definition of "AWS." Then, (...) I arrange my arguments by the Just War Theory (JWT), covering jus ad bellum, jus in bello and jus post bellum problems. Meanwhile, I draw attention to similar problems against other AI-technologies outside the JWT framework. Finally, I address an exception, as addressed by Duncan Purves, Ryan Jenkins and Bradley Strawser, who realized the unjustified double standard, and deliberately tried to construct a special argument which rules out only AWS.

Raymond Aron was a student of Léon Brunschvicg, a representative of French historical epistemology. This article explores Aron’s relation to this tradition through three claims. First of all, it contests that Raymond Aron’s philosophy of history constituted a complete break with this tradition. Secondly, resituating Aron in this tradition is valuable, because it highlights how Aron’s own philosophy of history is to be understood as a normative project, seen as an alternative to that of Brunschvicg. (...) Finally, Aron’s philosophy can still hold valuable lessons for present-day historical epistemology and history and philosophy of science in general. (shrink)

Aron’s writings are lauded for their contributions to liberal political theory, international relations, and sociology. I argue that his early thought also offers phenomenological considerations for a relativist view of historical meaning, whose important role in the text’s argument has been suppressed by received interpretations. Drawing a direct link between introspective, intersubjective, and historical understanding, Aron argues that the “objectification” of intentions necessarily transforms their meaning. This impedes an objective account of historical subjects’ lived experience. Some of the (...) Introduction’s appraisals of historical understanding rely on Aron’s phenomenological observations, and indicate that the intentionality of historical understanding circumscribes claims to historical objectivity. These results highlight the broader implications of largely overlooked phenomenological commitments in Aron’s thought, offer a fresh interpretation of the Introduction, and suggest that the standard account of Aron’s relation to the phenomenological movement should be reconsidered.

This paper analyses the interpretation of the Marxist dialectic proposed by three important French philosophers of the twentieth century: Maurice Merleau-Ponty (1908-1961), Jean-Paul Sartre (1905-1980) and Raymond Aron (1905-1983). Starting from different theoretical and political points of view, they criticize the historical determinism of the Marxist dialectic and propose three different “philosophies of freedom.” In the Adventures of the Dialectic (1955), Merleau-Ponty criticizes a theory of human history based only on economic structure, and denounces the violence of the Soviet (...) communism. He also accuses his friend Sartre – who had a more favourable attitude towards Soviet communism – of “ultrabolshevism.” Merleau-Ponty was subsequently active in the French non-communist Left. The existentialist philosopher Sartre always sympathized with the Left, and supported the French Communist Party (PCF) until the 1956 Soviet invasion of Hungary. In his Critique of Dialectical Reason (1960), Sartre also underlined the failure of the Soviet revolution, and criticized the violence of Marxist revolutionary thought. The last part of this paper deals with the philosopher and political sociologist Raymond Aron, who had a lifelong, sometimes fractious, friendship with Sartre. He always defended a “skeptical and anti-ideological” liberal position. In his best known book The Opium of the Intellectuals (1955), Aron argues that in post-war France, Marxism was the opium of the intellectuals. In this book, Aron chastised French intellectuals for what he described as their harsh criticism of capitalism and democracy and their simultaneous defense of Marxist oppression, atrocities, and intolerance. In opposition to the dialectical ideology of Marxism, Aron proposes an antitotalitarian philosophical and political theory based on the development of individual liberties. (shrink)

Induced by intake of the psychedelic substances LSD, psilocybin, DMT and mescaline, psychedelic experiences have been extensively described by subjects as entailing a most unusual increase in the scope and quality of their consciousness. Accordingly, psychedelic experiences have been widely characterised as an “expansion of consciousness.” This article poses the following question, as yet unaddressed in contemporary philosophy and the tradition of phenomenology: to what exactly does “expansion of consciousness” refer as a general characterisation of psychedelic experiences, and what role (...) might attention play therein? On the basis of Aron Gurwitsch’s phenomenology of attention, the following thesis is presented: (a) “expansion of consciousness” refers to a particular restructuration of consciousness in psychedelic experiences. (b) This occurs by means of certain extreme transformations in direction, scope, mode and degree of attention. In order to explicate this thesis, the characteristic features of psychedelic experiences that pertain to expansion of consciousness and attention are first systematically identified from a survey of subject reports. Second, it is demonstrated that the few previous attempts to understand expansion of consciousness in terms of attention as a filter/reducing-valve, spotlight or zoom-lens each fail to explain how consciousness is structured in psychedelic experiences. Third, it is argued that psychedelic expansion of consciousness is a general restructuration of consciousness by means of extreme attentional transformations. In conclusion, brief consideration is given to the question of whether psychedelic expansion of consciousness can have epistemic and ethical value for life. (shrink)

ABSTRACT With the aim of showing what it takes to see the world and others as they are, this article provides a phenomenological account of what Iris Murdoch has memorably called “the work of attention.” I first show that Aron Gurwitsch’s analyses of attention provide a basis on which to reject a voluntaristic account of attention according to which seeing things as they are is as simple as directing one’s attention to something. Then, in order to elucidate the work (...) that is involved in paying attention, I draw on Edmund Husserl’s descriptions of the activity characteristic of attentive consciousness. I then show how a Husserlian account of the work of attention can help make sense of Murdoch’s pessimistic claim that our consciousness is not “a transparent glass through which it views the world” while also indicating how we, by paying attention, can do better.

The aim of this essay is explore what demands living in liberty places on citizens in Montesquieu’s The Spirit of the Laws. In contrast to the ideas of liberty from many of the thinkers that were to follow him, Montesquieu’s notion of liberty requires that citizens subject themselves to the regulative relationships required by his normative conception of the law. For Montesquieu, living in liberty is not just a situation in which one avoids what the law forbids and is otherwise (...) left ’free’ without interference and coercion. For Montesquieu, liberty is a positively elaborated ideal with normative demands and a set of “necessary relations” that citizens must form. The result is that a life of liberty is defined in a significant way by the laws that bind a citizen because liberty is not the freedom to construct different ways of life, but the freedom to live securely within a particular way of life. I highlight this overlooked feature of The Spirit of the Laws by mobilizing Aron, Althusser and Durkheim’s work on the law in Montesquieu to draw out the implications of Montesquieu’s notion of law for liberty.

Aron Gurwitsch made two main contributions to phenomenology. He showed how to import Gestalt theoretical ideas into Husserl’s framework of constitutive phenomenology. And he explored the light this move sheds on both the overall structure of experience and on particular kinds of experience, especially perceptual experiences and conscious shifts in attention. The primary focus of this paper is the overall structure of experience. I show how Gurwitsch’s Gestalt theoretically informed phenomenological investigations provide a basis for defending what I will (...) call Phenomenal Holism, the view that all the parts of a total phenomenal state metaphysically depend on it. To illustrate how the ideas developed along the way can be used in advancing work on the phenomenology of particular kinds of experience, I draw on them in defending Husserl’s view that we can be aware of abstract objects against a phenomenological objection.

Evidentialists say that a necessary condition of sound epistemic reasoning is that our beliefs reflect only our evidence. This thesis arguably conflicts with standard Bayesianism, due to the importance of prior probabilities in the latter. Some evidentialists have responded by modelling belief-states using imprecise probabilities (Joyce 2005). However, Roger White (2010) and Aron Vallinder (2018) argue that this Imprecise Bayesianism is incompatible with evidentialism due to “inertia”, where Imprecise Bayesian agents become stuck in a state of ambivalence towards hypotheses. (...) Additionally, escapes from inertia apparently only create further conflicts with evidentialism. This dilemma gives a reason for evidentialist imprecise probabilists to look for alternatives without inertia. I shall argue that Henry E. Kyburg’s approach offers an evidentialist-friendly imprecise probability theory without inertia, and that its relevant anti-inertia features are independently justified. I also connect the traditional epistemological debates concerning the “ethics of belief” more systematically with formal epistemology than has been hitherto done. (shrink)

This doctoral thesis was prepared in 1975-77 at Ecole des Hautes Etudes en Sciences Sociales, Paris, under the supervision of Prof. Raymond ARON. It was submitted in 1977 in fulfilment of the requirements for a Ph.D. degree in Social Sciences (Doctorat de 3e cycle en sciences sociales). The oral examination (soutenance de thèse) was held in January 1978, with the examination committee consisting of Prof. Aron, Bartoli, Boudon and Brochier. This 250 page unpublished dissertation was the first study (...) ever written in French on Karl Marx's Grundrisse - a 1857-58 manuscript preparatory to Marx's main economic work, Capital. The dissertation reviews Marx's successive projects for his economic work since the 1844 Manuscripts and then proceeds to a presentation and critical discussion of Grundrisse. The proposed interpretation explains the linkage that Marx operated in 1857-58 between Ricardo's economics and Hegel's dialectics, and it emphasizes that Marx was at that time primarily trying to reconstruct the dynamics of capitalism, without going to the stage of developing a formal theory of value and exploitation, as he will eventually do in Capital.

This essay is a short but impacting observation of the economy of the Middle Ages in light of recent economic historians’ discoveries: not only are some conventional beliefs such as the absence of a financial and trading economy of the period discredited, but a more nuanced view of feudalism also emerges from such revelations. The new, groundbreaking work of Michael McCormick is pitted against Henri Pirenne’s classic theory; in addition, seminal works by Marc Bloch, S.R. Epstein, and lesser known work (...) by Aron Gurevich provide a more authentic view of Middle-Age economy. Finally, contrary to Marxist historiography, this essay postulates that to some extent feudalism fomented the development of capitalism. (shrink)
