Roderick Chisholm

In this paper, I offer an understanding of G.E. Moore’s epistemology as presented in, “A Defence of Common Sense” and “Proof of an External World”. To frame the discussion, I look to Roderick Chisholm’s essay, The Problem of the Criterion. I begin by looking at two ways that Chisholm believes one can respond to the problem of the criterion, and, referring back to Moore’s essays, explain why it is not unreasonable for Chisholm to believe that he is following a line (...) of reasoning that Moore might take. I then show why I believe Chisholm is actually trying to do something quite different from what Moore was, and thus misses Moore’s actual point. I conclude that Moore is best understood as rejecting traditional epistemological concerns. By forcing Moore to deal with a traditional epistemological problem, it will become clear how bold Moore’s “epistemology” is. (shrink)

This paper explores a particularist element in the theory of method of Imre Lakatos, who appealed to the value-judgements of élite scientists in the appraisal of competing theories of method. The role played by such value-judgements is strongly reminiscent of the epistemological particularism of Roderick Chisholm. Despite the existence of a clear parallel between the particularist approaches of both authors, it is argued that Lakatos’s approach is subject to a weakness that does not affect the approach of Chisholm.

In this paper I focus on the conditions that have to be met for Chisholm’s Paradox (CP) to occur. My claim is that identity and structure are notions closely related to each other. I propose a discussion in which the minimal framework for CP is set, then analyze the paradox in terms of S5, and suggest that in order to capture the core of the paradox one should use a dynamic valuation function for the model. Identity appears, at this point, (...) to be dependent upon a structuralist point of view. (shrink)

Since it was presented in 1963, Chisholm’s paradox has attracted constant attention in the deontic logic literature, but without the emergence of any definitive solution. We claim this is due to its having no single solution. The paradox actually presents many challenges to the formalization of deontic statements, including (1) context sensitivity of unconditional oughts, (2) formalizing conditional oughts, and (3) distinguishing generic from nongeneric oughts. Using the practical interpretation of ‘ought’ as a guideline, we propose a linguistically motivated logical (...) solution to each of these problems, and explain the relation of the solution to the problem of contrary-to-duty obligations.

Cet article esquisse une réponse particulariste et naturaliste au relativisme épistémique. La réponse est basée sur une analyse spécifique de la source de relativisme épistémique. Selon cette analyse, le relativisme épistémique doit être considérée en lien proche avec le scepticisme pyrrhonien, car le relativisme est basée sur le problème du critère qui a été propose par les ces anciens sceptiques. L’article commence avec une caractérisation du relativisme épistémique. Puis il présente un argument pour le relativisme épistémique sur la base du (...) problème du critère. La réponse au problème du critère proposée par Roderick Chisholm est ensuite considérée. La réponse de Chisholm est fondée sur un particularisme épistémique. Apres avoir présenté l’approche de Chisholm, l’article propose une réponse au relativisme épistémique qui combine le particularisme de Chisholm avec une approche naturaliste et fiabiliste aux questions épistémiques. Quelques remarques à propos du lien entre Chisholm et la réponse proposée au relativisme épistémique sont aussi offertes. (shrink)

In previous work, I have sought to show that the basic argument for epistemic relativism derives from the problem of the criterion that stems from ancient Pyrrhonian scepticism. Because epistemic relativism depends upon a sceptical strategy, it is possible to respond to relativism on the basis of an anti-sceptical strategy. I argue that the particularist response to scepticism proposed by Roderick Chisholm may be combined with a naturalistic and reliabilist conception of epistemic warrant as the basis for a satisfactory response (...) to epistemic relativism. In this paper, I outline this particularist response to relativism, and provide further commentary on the relationship between naturalism and particularism. In addition, I set the approach in contrast with reflective equilibrium approaches in epistemology. I also briefly explore the connection between the particularist response to relativism and G. E. Moore’s defense of an external world. (shrink)

What is the relationship between saying ‘I know that Q’ and guaranteeing that Q? John Austin, Roderick Chisholm and Wilfrid Sellars all agreed that there is some important connection, but disagreed over what exactly it was. In this paper I discuss each of their accounts and present a new one of my own. Drawing on speech-act theory and recent research on the epistemic norms of speech acts, I suggest that the relationship is this: by saying ‘I know that Q’, you (...) represent yourself as having the authority to guarantee that Q.

Roderick M. Chisholm (1916-1999) was one of the most important philosophical thinkers of the 20th century. His influence on epistemology (the theory of knowledge) and metaphysics cannot be understated; indeed, it is difficult to conceive of what these fields would be like today without the impact of Chisholm. Were there a Nobel Prize in philosophy, Chisholm surely would have won it.
