The rich philosophical and mathematical disputes that took place between Isaac Newton and Gottfried Leibniz at the start of the eighteenth century have received more historical attention than any other exchange in the history of philosophy. Nevertheless, in this talk, Robert Iliffe discusses a prominent but neglected aspect of their disagreement, namely the mutual claim that their opponents’ conceptual foundations were fictional, and were the product both of diseased thinking and of illegitimately organized intellectual structures. Newton assailed Leibniz’s allegedly debased metaphysics in various prominent places, and mobilized allies such as Roger Cotes and John Keill to do the same. Nevertheless, by far the most sophisticated critique of illicit philosophical assumptions was launched against Newton by Leibniz in his correspondence with Samuel Clarke. In the Fifth letter to Clarke, Leibniz identified core Newtonian positions as infantile, vulgar, and profoundly irreligious, asserting that they were dangerous fictions that were less plausible and much less edifying than the rational romances of writers in the previous century. Although Leibniz saved his most potent intellectual weapons for his final letter to Clarke, Robert Iliffe suggests that his attack on the fictional status of Newton’s work was no mere codicil to his general critique of Newton’s philosophy, but instead lay at the heart of it. This famous debate, while of course somewhat sui generis, is indicative of more general and dynamic features of intellectual debate.

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.

Presented by Columbia University Dept. of Philosophy

The COVID-19 pandemic is said to be a once-in-a-century incident, and it brought to us a sense of crisis at various levels. What is a crisis, though? Can any unnerving moment or period be called a crisis, or are there different dimensions of a crisis to which we need to be attentive? Is solidarity possible after experiencing a crisis like Covid-19? Can Buddhism make any contribution to facilitating solidarity? This presentation explores the meaning and nature of a crisis and our responses to it by drawing on modern Korean political thinker Pak Ch’iu’s (1909–1949) analysis of crisis and feminist-Buddhist thinker Kim Iryŏp’s (1896–1971) Buddhist philosophy. By doing so, this presentation considers what social, political, existential, and even religious meaning we can draw from our experience of crises, and what questions these insights present to us.

Well-being, also known as prudential value, refers to whatever makes a life non-instrumentally good for the person living it. Well-being is the object of immense practical, philosophical, and scientific concern. Assessments of well-being help to guide our decisions in everyday life, from relationships, to health decisions, to education and career choices. Well-being is increasingly the object of governmental and institutional policy, and even policies that are not aimed directly at promoting it can be evaluated in terms of their impacts on well-being. Colleges and universities routinely offer programs designed to help students maintain their well-being in the face of academic and personal stress. However, debates over the nature of well-being have raged since the beginning of philosophical inquiry, leaving us in a bad position when it comes to making headway on addressing those practical and scientific concerns. The goal of this talk is to show how the application of naturalistic methodology can help us to resolve the philosophical stalemate and thus to make progress in our practical and scientific projects relating to well-being.

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.
