In lieu of an abstract, here is a brief excerpt of the content:64. ON HUME'S IS-OUGHT THESIS The famous thesis of Hume about "is" and "ought" I take to be, as I believe it has generally been taken to be: (1) For any factual statement e and any ethical statement h, h is not deducible from e. My object in these brief notes is neither to defend nor to attack (1), but just to point out certain mistakes which have been (...) made, or are apt to be made, about (1), or about what Hume's thesis is. A. Max Black has taken Hume's thesis to be that "only statements of fact can follow- from statements of facti* ¡ a thesis, Black thinks, which Popper and "many other philos c be ; osophers" believe. That is. Black took Hume's thesis to (2)For any factual e and any non-factual h, h is not deducible. from e. It is certain, however, that Popper does not believe (2), and I hope it is untrue that many other philosophers believe it. For (2) is obviously false, and on the contrary, every factual statement has at least one nonfactual consequence; since from any factual statement 'f, the statement *f or not-f, which is not factual, is deducible. But this leaves Hume's thesis (1) untouched, since there is no excuse for confusing it with the foolish thesis (2). B. If a statement h is not deducible from a statement e, then given e, the falsity of h is possible; or in other words, h has less than maximum probability in relation to e. So part at least of the content of Hume's thesis (1) is: (3)For any factual e and ethical h, P(h/e). (shrink)

The aim of this article is twofold. First, it is argued that while the principle of ‘ought implies can’ is certainly plausible in some form, it is tempting to misconstrue it, and that this has happened in the way it has been taken up in some of the current literature. Second, Kant's understanding of the principle is considered. Here it is argued that these problematic conceptions put the principle to work in a way that Kant does not, so that there (...) is an important divergence here which can easily be overlooked.

Professionals have a role obligation to satisfy certain standards when performing their work. However, as professionals, can they perform morally praiseworthy acts that are not within the scope of duty? According to applied professional ethics, the answer is yes, whereas some theoretical accounts of supererogation deny this possibility. I examine and ultimately reject two very different theoretical accounts that deny professional supererogation. First, a recent interpretation of Aristotle uses examples from the professional context to illustrate that the moral category of (...) supererogation is not needed to describe heroic acts. Second, David Heyd’s account of supererogation argues that the category applies to natural duties alone and not to professional as professionals. Contrary to these claims, I argue that it is not only conceptually coherent to allow for the possibility of going beyond the call of duty but also morally important for assessments of responsibility and blame in professional life.

The two theories of verbal cognition, namely abhihitānvaya and anvitābhidhāna, first put forth by the Bhāṭṭa and Prābhākara Mīmāṃsakas respectively in the second half of the first millennium C.E., can be considered as being foundational as all subsequent thinkers of the Sanskritic intellectual tradition engaged with and elaborated upon these while debating the nature of language and meaning. In this paper, I focus on the first chapter of Śālikanātha’s Vākyārthamātṛkā and outline the process of anvitābhidhāna described therein. Śālikanātha explains this (...) as comprising three steps, and thereafter discusses each of these three to elaborate upon and philosophically defend this conception of how one cognizes sentential meaning. The aim of this paper is to present Śālikanātha’s three-step model, and thus demonstrate especially the distinct conception of abhidhāna for the Prābhākara Mīmāṃsakas as complex and chronologically extended as contrasted with the Bhāṭṭa conception of abhidhāna as non-complex and instantaneous. Such an understanding of the disparate semantic contents with which the Bhāṭṭas and Prābhākaras use the identical term abhidhāna is crucial for any correct study of their respective doctrines.

The Mīmāṃsā school of Indian philosophy has for its main purpose the interpretation of injunctions that are found in a set of sacred texts, the Vedas. In their works, Mīmāṃsā authors provide some of the most detailed and systematic examinations available anywhere of statements with a deontic force; however, their considerations have generally not been registered outside of Indological scholarship. In the present article we analyze the Mīmāṃsā theory of Vedic injunctions from a logical and philosophical point of view. The (...) theory at issue can be regarded as a system of reasoning based on certain fundamental principles, such as the distinction between strong and weak duties, and on a taxonomy of ritual actions. We start by reconstructing the conceptual framework of the theory and then move to a formalization of its core aspects. Our contribution represents a new perspective to study Mīmāṃsā and outlines its relevance, in general, for deontic reasoning. (shrink)

Although not entirely mainstream, uses of formal methods for the study of the history of philosophy, the history of logic in particular, represent an important trend in recent philosophical historiography. In this chapter, I discuss what can be achieved by the application of formal methods to the history of philosophy, addressing both motivations and potential pitfalls. The first section focuses on methodological aspects, and the second section presents three case studies of historical theories which have been investigated with formal tools: (...) Aristotle’s syllogistic, Anselm’s ontological argument, and medieval theories of supposition. (shrink)
