This article is aimed at those interested in the philosophy of Gilles Deleuze and the sciences—and this includes philosophers of science working out of the analytic tradition. Deleuze's writings are riddled with references to science and mathematics. And yet, the relation between these references and his philosophical thought is not well understood. In this essay, I investigate the nature of this relation—and I do so by asking whether it is naturalistic. Importantly, I draw on insights from contemporary philosophy of science to contribute to a proper understanding of this issue. I show that and how commentators are hamstrung by their lack of engagement with the philosophy of science; I present an interpretation of Deleuze's philosophical project as attempting to articulate an immanent and primitive form of objective modality; I draw together parts of Deleuze's corpus that are relevant to his treatment of the sciences but are nonetheless rarely studied in conjunction (including his and Guattari's distinction between ‘major’ and ‘minor’ science and his under-scrutinized statement of interest in ‘the metaphysics science needs’); and I propose a naturalistic interpretation of his engagements with science.
Although Husserlian phenomenology appears to require that practitioners bracket all metaphysical questions and claims, this requirement runs against the evidence of experience in which objects themselves are presented as constituents of experience. Moreover, to completely bracket metaphysical considerations would suggest that phenomenology is compatible with metaphysical views it should in principle deny. Nonetheless, permitting metaphysical claims threatens to contravene the critical limits of phenomenology, to invite claims that would require a perspective different in kind than our own to verify. These tensions raise an important question, namely, what are the metaphysical implications of the phenomenologically intuitive claim that objects themselves are constituents of experience? To answer this question, I draw on a broad swath of thought on transcendental idealism and phenomenology. I argue that a modest metaphysics of appearance is warranted within the critical limits of Husserlian phenomenology. Through discussing and addressing the problems that typically plague transcendental arguments, I show that Husserlian phenomenology permits stronger claims about objects of experience than deflationary accounts allow but does not permit claims about intrinsic properties allowed by some forms of transcendental idealism.
How does the publication of Confessions of the Flesh impact feminist critique of Foucault's History of Sexuality project? The paper addresses this question in two ways: by asking how reflection on continuities and ruptures has, and can, be productive for feminist critique; and by revisiting the role of women in all four volumes. The terms of their inclusion have been considered an omission, particularly because the project omits same-sex eros between women. Where women appear, they are framed as spouses, or as subordinated to some form of authority. And yet, insofar as the project contains more than one genealogical dimension, Foucault's “marriages” also belong to proximate plurigenealogies. In Confession's focus on the conditions for a juridical and divided self's subjectivation by will and desire, even the limited parameters within which women appear in the project incite the following question. What are the implications of Confessions of the Flesh's juridical self for genealogies of female subjectivation?
Many persons find it intuitive that being friends with someone with immoral beliefs is wrong as such. I contest this claim, instead I argue that there is nothing necessarily wrong with such friendships. In coming to this conclusion I examine a number of arguments, including two of the most notable contributions put forward by Mason (2021) and Isserow (2018), that attempt to elucidate the wrongness involved in such friendships and find they do not successfully do so. I conclude by offering some arguments as to why such friendships are not necessarily wrong.
To commemorate the centenary of Ernst Cassirer's Philosophy of Symbolic Forms this essay focuses on how Cassirer in the development of a distinctive philosophical method analyzed the newest development within philosophy and science. Discussing Einstein's theory of relativity and Russell's formal logic Cassirer found tools to expand the critique of reason into a critique of culture. The course of argumentation is as follows. At the outset Cassirer's outline of the idea of The Philosophy of Symbolic Forms in the 1920 book Einstein's Theory of Relativity is presented as a reaction to the increasing distance between theoretical physics and ordinary experience. The Philosophy of Symbolic Forms can be read as an answer to an inner methodological demand within critical idealism. I encircle this motif in Cassirer's comment that Plato's idealism, understood as the dianoia of thought, is reiterated in Kant's transcendental philosophy and Herman Cohen's reception of Kant. This leads to a discussion of how Cassirer breaks away from Cohen by the positive reception of Russell's symbolic logic. Finally, I present the theory of functional concepts developed by Cassirer (1910) in the book Substance and Function as a prerequisite for the conception of a plural but systematic philosophy of symbolic forms.
What are Carnap's views on the epistemology of mathematics? Did he believe in a priori justification, and if so, what is his account of it? One might think that such questions are misguided, since in the 1930s Carnap came to reject traditional epistemology as a confused mixture of logic and psychology. But things are not that simple. Drawing on recent work by Richardson and Uebel, I will show that Carnap's mature metaphilosophy leaves room for two distinct notions of a priori justification: one propositional, the other doxastic. The latter is especially interesting since it comes closest to a traditional understanding of a priority. On the other hand, Carnap has little to say about doxastic justification in his writings. This lacuna can be filled by drawing on an unpublished exchange with Irving M. Copi. In it, so I will show, Carnap endorses the view that agents can come to know all mathematical truths a priori. This fact, so I will further argue, can be used to adjudicate a dispute between Ricketts and Friedman about the nature and viability of Carnap's philosophy of mathematics—specifically his reliance on infinitary methods.
In an archived draft at the Bibliothèque nationale de France, Foucault describes two questions haunting him since 1963: “Why are we obliged to tell the truth about ourselves? Which truth?” Foucault poses these two questions in 1980 in drafts for his lectures at the University of California, Berkeley, and I see in these two questions two argumentative threads that weave through Foucault's changing History of Sexuality series over his last decade. These two threads correspond to the dimorphism Foucault frames in Part III of Confessions of the Flesh between confessing monks and married men, that correlates with the distinction between “veridiction” and “juridiction” as two forms relating subjectivity and sexuality. To help tease out these threads, I make two recommendations for how to read Confessions of the Flesh in this following review essay: (1) situate Confessions of the Flesh in relation to Foucault's History of Sexuality series which spans his last decade from 1974 to 1984 and (2) untangle two major threads of Confessions of the Flesh in Foucault's treatment of Cassian and Augustine, as progenitors of veridiction and juridiction respectively, which together produce the conditions for modern disciplinary subjects.
