Comme de nombreux penseurs antiques avant et après eux et contrairement à Socrate, Calliclès et Diogène ont déclaré avoir fondé leur éthique sur l’observation de la nature. Et pourtant, les deux discours normatifs qui sont tirés d’une nature que l’on pourrait a priori croire être la même sont on ne peut plus opposés. Calliclès croit que l’homme est appelé à dominer autrui ; Diogène pense plutôt qu’il doit se dominer lui-même ; le premier est un hédoniste débridé, le second croit que le bonheur ne s’achète qu’au prix du sacrifice des désirs artificiels. Comment expliquer cette dichotomie ? Nous empruntons deux routes explicatives. D’abord, nous montrons que pour Calliclès et Diogène, la notion de nature non seulement diffère, mais est observée sous un angle différent. La première est celle des tyrans et de dieux anthropomorphes, la seconde, celle de petits animaux et de dieux autarciques. La première concerne la relation des hommes entre eux ; la seconde, celle de l’homme avec lui-même. Ensuite, nous exposons la différence des présupposés normatifs qui précèdent ou accompagnent l’observation de la nature ; nous contrastons, pour ce faire, les formes d’anticonventionnalisme et d’anti-intellectualisme défendues par Calliclès et Diogène. SUMMARY. Like many ancient thinkers before and after them and contra Socrates, Callicles and Diogenes said they based their ethics on the observation of nature. And yet, the two normative discourses that are derived from nature that we might a priori believe to be the same could not be more opposed. Callicles believes that people are called to dominate others, Diogenes rather thinks people must dominate themselves. The first is an unbridled hedonist, the second believes that happiness can be bought only at the price of sacrificing artificial desires. How to explain this dichotomy? We take two explanatory routes. First, we show that for Callicles and Diogenes, the notion of nature not only differs but is observed from a different angle. The first one is the nature of tyrants and anthropomorphic gods, the second that of small animals and autarkic gods. The first focuses on the relationship between people, the second focuses on the relationship of a person with themselves. Secondly, we expose the difference in normative assumptions that precede or accompany the observation of nature; in order to do so, we contrast anticonventionalism and anti-intellectualism forms proper to both Callicles and Diogenes.

I offer an unorthodox argument for the thesis that prostitution is not just a normal job. It has the advantage of being compatible with the claim that humans should have full authority over their sexual life. In fact, it is ultimately the emphasis on this authority that leads the thesis that prostitution is a normal job to collapse. Here is the argument: merchants cannot (both legally and morally) discriminate whom they transact with on the basis of factors like the ethnicity or the religion of their client; but if prostitutes are ‘sex merchants’, then they cannot (both legally and morally) discriminate whom they have sex with on the basis of these factors. Yet everyone should have the full discretionary power to refuse to have sex under any circumstances.

Ce compte-rendu résume les quatre dimensions de la philosophie de l’ action défendue dans Action, Knowledge and Will : physique, éthique, psychologique et intellectuel. Cela dit, les deux contributions principales du livre recensé relèvent de liens entre les différentes dimensions de l’ action. Il s’agit d’une distinction et d’une connexion. Premièrement, Hyman croit qu’il faut distinguer la dimension éthique et la dimension physique de l’ action. Plus précisément, il pense que le concept de volonté et le concept de volontaire doivent être différenciés du concept d’ action ou de celui d’agencité, et d’actif. Deuxièmement, Hyman nous propose de connecter la dimension intellectuelle de l’ action avec la connaissance en avançant une théorie de la connaissance comme étant l’habileté d’être guidé par des faits.

No one is responsible for their conduct because free will is an illusion, say some skeptics. Even when it seems that we have several options, we only have one. Hence, says the free will skeptic, we should reform our practices which involve responsibility attributions, such as punishment and blame. How seriously should we take this doctrine? Is it one that we could live by? One thorn in the side of the skeptic concerns deliberation. When we deliberate about what to do—what film to go see, whom to befriend, which doctrine to follow—we must presume that our options are open to us. But then, every time that skeptics deliberate, they presume something which is incompatible with their doctrine, i.e. that they have several options. In a word, skeptics cannot deliberate qua skeptics. Some philosophers have responded that deliberators don’t have to presume that their options are open; they only have to presume that their choice will be efficacious. I argue that this proposal uses resources which, if they are available and successful, can be employed to refute skepticism. The upshot is that free will skeptics are pushing for a doctrine that is either false or in tension with deliberation.

In this leçon inaugurale (inaugural lecture) at the University of Neuchâtel, I explain how we can tackle the problem of determinism by asking whether it would give us a justification, an excuse, or an exemption. This strategy builds on Peter Strawson's in Freedom and Resentment, but completes it by (1) proposing a theory of excuses ; (2) proposing that lacking alternatives might give a weak justification--i.e. it might exclude wrongdoing. This forces us to make the best of two philosophical traditions, namely semi-compatibilism (à la Frankfurt/Fischer) and compatibilism (à la Lewis/Vihvelin). My proposal is that whereas compatibilism may have the upper hand, semi-compatibilists have always been right about excuses.

Suppose I am a leeway sceptic: I think that, whenever I face a choice between two courses of action, I lack true alternatives. Can my practical deliberation be rational? Call this the Deliberation Question. This paper has three aims in tackling it. Its constructive aim is to provide a unified account of practical deliberation. Its corrective aim is to amend the way that philosophers have recently framed the Deliberation Question. Finally, its disputative aim is to argue that leeway sceptics cannot deliberate entirely rationally about what to do, because of the connection between deliberating and deciding.

We have no reason to believe that reasons do not exist. Contra Bart Streumer’s recent proposal, this has nothing to do with our incapacity to believe this error theory. Rather, it is because if we know that if a proposition is true, we have no reason to believe it, then we have no reason to believe this proposition. From a different angle: if we know that we have at best misleading reasons to believe a proposition, then we have no reason to believe it. This has two consequences. Firstly, coming close to believing the error theory is idle or pointless. Secondly, philosophers who argue that believing sweeping theories like determinism or physicalism is self-defeating because they are either false or believed for no reason pursue a worthwhile argumentative strategy.

Free will sceptics deny the existence of free will, that is the command or control necessary for moral responsibility. Epicureans allege that this denial is somehow self-defeating. To interpret the Epicurean allegation charitably, we must first realise that it is propositional attitudes like beliefs and not propositions themselves which can be self-defeating. So, believing in free will scepticism might be self- defeating. The charge becomes more plausible because, as Epicurus insightfully recognised,there is a strong connection between conduct and belief—and so between thecontent of free will scepticism (since it is about conduct) and the attitude of believing it. Second, we must realise that an attitude can be self- defeating relative to certain grounds. This means that it might be self-defeating to be a free will sceptic on certain grounds, such as the putative fact that we lack leeway or sourcehood. This charge is much more interesting because of the epistemic importance of leeway and sourcehood. Ultimately, the Epicurean charge of self-defeat fails. Yet, it delivers important lessons to the sceptic. The most important of them is that free will sceptics should either accept the existence of leeway or reject the principle that ‘“ought” implies “can”’.

Le solidarisme de Léon Bourgeois constitue une tentative convaincante de surmonter l’opposition traditionnelle entre libertés individuelles et justice sociale. Bourgeois tente de relever ce défi en faisant appel aux nouvelles découvertes scientifiques en sociologie comme en biologie. En bref, l’observation de la nature nous montrerait que les humains sont en rapport de solidarité les uns avec les autres. De ce fait, on pourrait tirer un devoir de solidarité que l’État serait à même d’imposer aux individus. Fonder une théorie politique sur des théories scientifiques présente un double risque : d’une part, subir l’influence des biologistes collectivistes et de leur vision organiciste de la société ; d’autre part et surtout, se rendre coupable du sophisme naturaliste. Nous exposerons comment Bourgeois tombe initialement dans le piège du sophisme naturaliste avant de s’en extirper. Entre son texte Solidarité (1987) et son Essai d’une philosophie de la solidarité (1907), la progression est frappante. Au final, donc, Bourgeois nous semble présenter une théorie politique qui, tout en s’inspirant des sciences, ne s’y assujettit pas.

A version of the principle of alternate possibilities claims that one is only blameworthy for actions which one was able to avoid. Much of the discussion about PAP concerns Frankfurt’s counterexamples to it. After fifty years of refined debates, progress might seem hopeless. Yet, we can make headway by asking: “what’s our reason for believing PAP?” The best answer is this: lacking eligible alternatives—alternatives whose cost is not too high to reasonably opt for—is a good excuse. Yet, this principle is subject to straightforward counterexamples, unless it is given an epistemicised reading. And in this latter case, it does not support PAP. So, PAP is unsupported, at least for now.

Free will sceptics claim that we lack free will, i.e. the command or control of our conduct that is required for moral responsibility. There are different conceptions of free will: it is sometimes understood as having the ability to choose between real options or alternatives; and sometimes as being the original or true source of our own conduct. Whether conceived in the first or in the second way, free will is subject to strong sceptical arguments. However, free will sceptics face a difficulty: doubting the existence of free will might itself be problematic, whether free will exists or not. Three main considerations are offered in support of this claim. Firstly, it is said that free will sceptics confuse contexts: even if they are right to doubt the existence of free will in the philosophy classroom, they are wrong to do so in other contexts, such as day-to-day interactions or a court of law. Secondly, it is said that free will scepticism is incompatible with inescapable and indispensable human practices such as practical deliberation or moral criticism and evaluation. For, to deliberate about what to do, we must presume that we have true options or alternatives. And to judge that some human practices are wrong, we need to assume the existence of moral responsibility. Thirdly, free will scepticism is sometimes said to be self-defeating, on the grounds that it cannot be rational to believe free will scepticism, because free will is required for rationality. This thesis critically assesses these arguments. None takes free will scepticism down, but all are instructive about how not to be a sceptic. They trace the ‘contours’ of free will scepticism by discrediting some conceptions of free will and some arguments for free will scepticism.

Here is a skeptical trilemma. We know that we are responsible. We do not know that determinism is false. Yet, if we do not know that determinism is false, we do not know that we are responsible. If we want to avoid the skeptical conclusion of rejecting the first claim, we ought to reject the third. It does not follow that compatibilism is true. But it follows that libertarianism, the view that we are responsible even though responsibility requires indeterminism, is unknowable, at least for now. To see this, we need to compare different forms of skepticism and their response.
