Convergence to the truth is viewed with some ambivalence in philosophy of science. On the one hand, methods of inquiry that lead to the truth in the limit are prized as marks of scientific rationality. But an agent who, by using some method, expects to always converge to the truth seems to fail a minimum standard of epistemic modesty. This point was recently brought home by Gordon Belot in his critique of Bayesian epistemology. In this paper I will study convergence to the truth theorems within the framework of Edward Nelson’s radically elementary probability theory. This theory provides an enriched conceptual framework for investigating convergence and gives rise to an appropriately modest from of Bayesianism.
The seminar is concerned with applying formal methods to fundamental issues, with an emphasis on probabilistic reasoning, decision theory and games. In this context “logic” is broadly interpreted as covering applications that involve formal representations. The topics of interest have been researched within a very broad spectrum of different disciplines, including philosophy (logic and epistemology), statistics, economics, and computer science. The seminar is intended to bring together scholars from different fields of research so as to illuminate problems of common interest from different perspectives. Throughout each academic year, meetings are regularly presented by the members of the seminar and distinguished guest speakers.

This paper considers Cornelius Castoriadis’s articulation of social imaginary significations with an emphasis on their link to the radical imaginary. Castoriadis wrote on social imaginary significations for more than thirty years, and his understanding of them changed significantly during this time, yet this is not reflected in debates on his work. The paper argues that there are three distinct phases in his reflections. The first phase can be dated 1964-1970. This early phase is characterized by Castoriadis’s break from Marx and subsequent settling of accounts with Marxism. Central to Castoriadis’s critique of Marx was the recognition of history (or: the social-historical) as the domain of meaning and unmotivated creation as the work of the radical imaginary. Importantly, Castoriadis also considered the intertwining of the imaginary with the symbolic, on the one hand, and with social doing, on the other. Castoriadis’s approach in this early phase can be considered phenomenological in the broad sense that Merleau-Ponty gave it in the Phenomenology of Perception. The second phase is dated 1970-1975; that is, the period in which Castoriadis wrote the second part of The Imaginary Institution of Society wherein he announced his turn to ontology. This is his most self-contained and systematic articulation of social imaginary significations. Castoriadis extends and develops his notion of magma in relation to social imaginary significations and emphasizes the social imaginary creation of a world ex nihilo as an ontological creation, whilst the radical imaginary is presented as a part of his emergent general ontology of à-être. The third ‘kaleidoscopic’ phase is dated 1976-1997 and may be understood as a period of consolidation and expansion. Although his basic understanding of social imaginary significations did not dramatically alter (although further developments are visible), his thought went in a myriad of different directions and patterns – hence kaleidoscopic — that nonetheless shaped a wider background against which his elucidation of social imaginaries were configured. His reconsideration of the sacred, the ‘ground power’ of institutions, and the development of a poly-regional ontology of the for-itself were key to this changing background. The paper will conclude with a critical engagement with the implications of the changing permutations of the imaginary element for Castoriadis’s thought.

Jacob Soll, in conversation with Pierre Force, John Shovlin, Carl Wennerlind, and Emmanuelle Saada
After two government bailouts of the U.S. economy in less than twenty years, free market ideology is due for serious reappraisal. In Free Market: the History of an Idea, Jacob Soll details how we got to this current crisis, and how we can find our way out by looking to earlier iterations of free market thought. Contrary to popular narratives, early market theorists believed that states had an important role in building and maintaining free markets. But in the eighteenth century, thinkers insisted on free markets without state intervention, leading to a tradition of ideological brittleness. That tradition only calcified in the centuries that followed. Tracing the intellectual evolution of the free market from Cicero to Milton Friedman, Soll argues that we need to go back to the origins of free market ideology in order to truly understand it—and to develop new economic concepts to face today’s challenges.
Jacob Soll is professor of history and accounting at the University of Southern California. He has been awarded numerous prestigious prizes including two NEH Fellowships, the Jacques Barzun Prize, a Guggenheim Fellowship, and, in 2011, the MacArthur Fellowship. He also advises political and financial leaders across the globe to promote accounting standards and financial transparency.
Joining Jacob Soll to discuss his book will be: Pierre Force, Professor of French and History at Columbia; John Shovlin, Professor of History at NYU; and Carl Wennerlind, Professor of History at Barnard College. Emmanuelle Saada, Professor of History and French at Columbia, will moderate the discussion.
This event is co-sponsored by the Maison Française and the Department of History.

ABSTRACT: Buddhist philosophers often draw a distinction between two different kinds of truth: conventional truth (saṃvṭi-satya) and ultimate truth (paramārtha-satya). Abhidharma Buddhists philosophers typically understand this distinction in terms of an ontological distinction between two different kinds of entities: ultimately real entities (paramārtha-sat) and conventionally real entities (saṃvṛti-sat). Similar to contemporary philosophical discussions about ordinary objects, Buddhist philosophers debate the ontological status of conventional entities and the semantics of discourse concerning them. Mark Siderits (2015, 2021, 2022) has influentially argued for an eliminitivist position he calls “Buddhist reductionism” that interprets the Abhidharma position as one that denies conventional entities exist but that retains discourse involving apparent reference to them. However, in a recent article Kris McDaniel (2019), a prominent defender of ontological pluralism, challenges that view by proposing that the Abhidharma Buddhist distinction between conventional truth and ultimate truth be “defined up” from a more basic distinction between two different ways an entity can exist: conventionally or ultimately. In this paper I argue that Saṃghabhadra’s account of conventional reality and truth does lends itself well to McDaniel’s proposal but I will also argue that the account of conventional and ultimate truth that results differs in important ways from the models he offers. I will end by offering a modification of McDaniel’s account of conventional truth that is derived from Saṃghabhadra’s pluralist ontology. That view will, unlike the views suggested by both Siderits and McDaniel, allow for there to be ultimate truths about what is conventionally true.

How does the imagination change us? Why should picturing ourselves a certain way have any real effect on what we are? These questions are central to debates in Buddhist tantric literature regarding the generation stage (utpattikrama), wherein practitioners visualize themselves as buddhas ensconsed in magnificent mandala-palaces. For some, this practice is what sets Buddhist tantra apart: through this “yoga of the imagination,” as David Shulman puts it, a practitioner can achieve buddhahood in a single lifetime. And yet, as the Buddhist tantric author Indrabhūti (8th century) argues, a pauper who imagines himself to be a king does not thereby become one—so, in the same way, practitioners who visualize themselves as buddhas will not thereby become buddhas. The mental imagery (ākāra) involved in this practice is just so much unreal fabrication. Why should it have real transformative effects? I’ll consider here how these debates played out in Sanskrit Buddhist tantric texts from the 10th–11th centuries. I’ll focus on early authors in the Kālacakra tradition, who upheld Indrabhūti’s critique of the generation stage, and authors like Ratnākaraśānti, Vāgīśvarakīrti, and Advayavajra (aka Maitrīpa), who each in their own way critiqued mental imagery yet defended the importance and effectiveness of generation-stage practice. In the first part of the paper, I’ll consider arguments against mental imagery as these appear in generation-stage practice texts and the early Kālacakra tradition. In the second part, I’ll turn to why we might think unreal mental imagery can nevertheless have real transformative effects, paying special attention to the ways Buddhist tantric authors writing in Sanskrit take up ideas from the tradition of dramatic theory (nāṭyaśastra) and Sanskrit culture more broadly.
