- The Evil Demon argument as based on closure plus meta-coherence(2018) Guillon, J.B. (Jean-Baptiste)Descartes’s Evil Demon argument has been the subject of many reconstructions in recent analytic debates. Some have proposed a reconstruction with a principle of Infallibility, others with a principle of Closure of Knowledge, others with more original principles. In this paper, I propose a new reconstruction, which relies on the combination of two principles, namely the Meta-Coherence principle (defended by Huemer) and the principle of Closure of Justification (best defended by Hawthorne). I argue that the argument construed in this way is the best interpretation of what is really at play in the Evil Demon intuition, and also that this argument is dialectically much stronger than previous reconstructions. If this is right, then the “Closure plus Meta-Coherence” argument is what anti-sceptics should really be attacking.
- If presentism is false, then I don’t exist. On common-sense presentism(Springer Nature, 2024) Guillon, J.B. (Jean-Baptiste)For many presentist philosophers, e.g. Zimmerman (Contemp Debates Metaphys 10:211–225, 2008), a central motivation in favour of presentism is that it is supposed to be part of common sense. But the fact that common-sense intuitions are indeed presentist is usually taken for granted (and sometimes also conceded by eternalists). As has been shown in other domains of philosophy (e.g. free will), we should be careful when attributing some supposed intuitions to common sense, and Torrengo (Phenomenology and Mind 12: 50–55, 2017) and Le Bihan (Igitur-Arguments Philos 9(1):1–23, 2018) have legitimately raised doubts about the assumption that common sense is presentist. In this paper, I take up this challenge and try to show that our common-sense intuitions do imply presentism. More precisely, the intuitions that I take to imply presentism are fundamental intuitions about our selves as conscious beings. The upshot is that presentism is so much embedded within our conception of our selves that if presentism is false, then I don’t exist!
- Réflexivité épistémique et défense forte du sens commun. Remarques sur l’épistémologie de Pascal Engel(2017) Guillon, J.B. (Jean-Baptiste)Dans cet article, je discute l’épistémologie de Pascal Engel, en particulier sa stratégie de réponse aux arguments sceptiques dans Va Savoir !. Après avoir présenté de manière synthétique (section 1) les grands axes de cette stratégie (c’est-à-dire la stratégie du « mooréanisme internaliste »), je reviens avec plus d’attention sur deux éléments de cette stratégie avec lesquels je suis en désaccord : (i) le rejet par Engel de tout principe de réflexivité épistémique, et (ii) le rejet par Engel d’une défense « forte » du sens commun. Je défends qu’un certain principe de réflexivité (à savoir le principe de MétaCohérence, défendu par Michael Huemer) ne peut pas être raisonnablement rejeté (section 2) ; puis je montre que l’épistémologie d’Engel ne permet pas d’apporter une réponse satisfaisante au défi sceptique que pose le principe de Méta-Cohérence (section 3). Enfin, je soutiens que la seule manière de répondre de manière satisfaisante à ce défi est de recourir (comme Reid, mais pas comme Moore, Lemos ou Engel) à une défense « forte » du sens commun, c’est-à-dire à une stratégie dans laquelle les propositions de sens commun sont justifiées parce que elles sont de sens commun (section 4).
- Divine Providence: fine-grained, coarse-grained, or something in between?(The John Paul II Catholic University of Lublin, 2020) Guillon, J.B. (Jean-Baptiste)Dariusz Łukasiewicz has investigated in depth the “Argument from Chance” which argues that the data revealing chance in the world are incompatible with Divine Providence. Łukasiewicz agrees that these data undermine the traditional model of Providence—a fine-grained model in which every single detail is controlled by God—but maintains that they are not incompatible with a coarse-grained model—in which God leaves to chance many aspects of history (including some horrendous evils). Furthermore, Łukasiewicz provides independent reasons to prefer this coarse-grained model. Even though I agree that a maximally fine-grained model is undermined by the scientific data, I argue that this is no sufficient reason to adopt a model as coarse-grained as Łukasiewicz’s. I propose a model of intermediate level of fine-grainedness which could avoid the drawbacks of both extremes, and seems to me to provide a more traditional approach to the problem of evil.
- The Dynamic Strategy of Common Sense Against Radical Revisionism(Springer, 2023) Guillon, J.B. (Jean-Baptiste)Common-sense philosophers typically maintain that common-sense propositions have a certain kind of epistemic privilege that allows them to evade the threats of skepticism or radical revisionism. But why do they have this special privilege? In response to this question, the “Common-Sense Tradition” contains many different strands of arguments. In this paper, I will develop a strategy that combines two of these strands of arguments. First, the “Dynamic Argument” (or the “starting-point argument”), inspired by Thomas Reid and Charles S. Peirce (but which will be strengthened with the help of Gilbert Harman’s epistemology of belief revision). Second, G.E. Moore’s “greater certainty argument” (interpreted along the lines of Soames’ and Pollock’s construal). This combined strategy, I will argue, is the strong core of Common-Sense Philosophy, and relies on extremely modest and widely held assumptions.
- A Common Sense Defence of Ostrich Nominalism(2021) Guillon, J.B. (Jean-Baptiste)When the meta-philosophies of Nominalism and Realism are compared, it is often said that Nominalism is motivated by a methodology of ontological economy, while Realism would be motivated by an appeal to Common Sense. In this paper, I argue that this association is misguided. After briefly comparing the meta-philosophy of Common Sense and the meta-philosophy of economy, I show that the core motivation in favour of Realism relies in fact in a principle of economy which violates the methodology of Common Sense. I conclude that Common Sense philosophers should endorse Nominalism (and more precisely Ostrich Nominalism).
- Van Inwagen on introspected freedom(2013) Guillon, J.B. (Jean-Baptiste)Any philosopher who defends Free Will should have an answer to the epistemological question: “how do we know that we have such a capacity?” A traditional answer to this question is that we have some form of introspective access to our own Free Will. In recent times though, many philosophers have considered any such introspectionist theory as so obviously wrong that it hardly needs discussion, especially when Free Will is understood in libertarian terms. One of the rare objections to appear as an explicit argument was proposed by van Inwagen in his Essay on Free Will. In this paper, I address van Inwagen’s anti-introspection argument; I argue that it is both inconsistent with his overall treatment of the Existence Question (namely, with his defence of the existence of Free Will from reflections about morality), and inconclusive in itself (at least for anyone not ready to endorse general scepticism about perception). In passing, I give a clarification of the notion of Introspection, in the case of Freedom, that also sets a more favourable stage for the evaluation of further objections.
- Coincidence as parthood(2021) Guillon, J.B. (Jean-Baptiste)There are three families of solutions to the traditional Amputation Paradox: Eliminativism, Contingent Identity Theories, and Theories of Coincident Entities. Theories of Coincident Entities challenge our common understanding of the relation between identity and parthood, since they accept that two things can be mereologically coincident without being identical. The contemporary discussion of the Amputation Paradox tends to mention only one theory of Coincident Entities, namely the Constitution View, which violates the mereological principle of Extensionality. But in fact, there is another theory, namely the Unique Part View, which violates another mereological principle (the Weak Supplementation Principle). In this paper, I argue that the contemporary focus on the Constitution View is unmotivated, at least when we are confronted with the Amputation Paradox, and that a balanced comparison of the two views (as solutions to this specific paradox) should favour the Unique Part View.
- “You Would Not Seek Me If You Had Not Found Me”—Another Pascalian Response to the Problem of Divine Hiddenness(2021) Guillon, J.B. (Jean-Baptiste)One version of the Problem of Divine Hiddenness is about people who are looking for God and are distressed about not finding him. Having in mind such distressed God-seekers, Blaise Pascal imagined Jesus telling them the following: “Take comfort; you would not seek me if you had not found me.” This is what I call the Pascalian Conditional of Hiddenness (PCH). In the first part of this paper, I argue that the PCH leads to a new interpretation of Pascal’s own response to the problem, significantly different from Hick’s or Schellenberg’s interpretations of Pascal. In short: for any person who is distressed about not finding God, and who (for this reason) seriously considers the Argument from Hiddenness, the PCH would show that their own distress constitutes evidence that God is in fact not hidden to them (because this desire for God has been instigated in them by God himself). In the second part of the paper, I set aside the exegetical question and try to develop this original strategy as a contemporary response to one version of the Problem of Divine Hiddenness, which I call the “first-person problem.” I argue that the PCH strategy offers a plausibly actual story to respond to the first-person problem. As a result, even if we need to complement the PCH strategy with other more traditional strategies (in order to respond to other versions of the problem), the PCH strategy should plausibly be part of the complete true story about Divine Hiddenness.
