Manley and Wasserman (2008) join the chorus of opposition to the possibility of conditional analysis of dispositions. But that score cannot be settled without more careful attention to the implicit philosophical methodology. Some of the opposition to such an analysis badly overestimates the effect of counterexamples, as if the Gettier example were sufficient to refute the possibility of conjunctive analysis of knowledge. A general objection to a form of analysis must satisfy a number of constraints, and Manley and Wasserman join (...) the chorus too in failing to satisfy them. Most significant is the optional presupposition that the conditional used in analysis will exhibit some sort of centring. We show that even a careful effort to repair and reform Manley and Wasserman's objection to provide a satisfactory argument requires, ultimately, appeal to centring. Worse, the particular positive proposal they offer is vulnerable to a minor variant of their own counterexample. (shrink)

The crucial feature of obligation sentences to which the puzzles point is that such sentences, and evaluative sentences more generally, are defeasible. They may be warranted, given some information, only to be defeated by further information. A theory that recognizes this no longer needs to see conditional obligation as anything more than a simple combination of unary obligation and the conditional.

To say that this lump of sugar is soluble is to say that it would dissolve, if submerged anywhere, at any time and in any parcel of water. To say that this sleeper knows French, is to say that if, for example, he is ever addressed in French, or shown any French newspaper, he responds pertinently in French, acts appropriately or translates correctly into his own tongue.

John McDowell, Richard Rorty, and Robert Brandom invoke Sellars's arguments against the Myth of the Given as having shown that the Given is nothing more than a myth. But most of Sellars's arguments attack logical atomism, not the framework of givenness as such. Moreover, they do not succeed. At crucial points the arguments confuse the perspectives of a knower and those attributing knowledge to a knower. Only one argument—the “inconsistent triad” argument—addresses the Myth of the Given as such, and there (...) are several ways of escaping its conclusion. Invocations of Sellars's refutation of the Myth of the Given are empty. (shrink)

Pragma-dialectics is dynamic, context-sensitive, and multi-agent; it promises theories of fallacy and argumentative structure. But pragma-dialectic theory and practice are not yet fully in harmony. Key definitions of the theory fall short of explicating the analyses that pragma-dialecticians actually do. Many discussions involve more than two participants with different and mutually incompatible standpoints. Success in such a discussion may be more than success against each opponent. Pragma-dialectics does well at analyzing arguments advanced by one party, directed at another party; it (...) does much less well at analyzing arguments directed at several opponents at once or at convincing an audience. I suggest a strategy of construing fallacies as defeasible arguments relying on reasonable default principles but applying them in circumstances in which they are undercut or overridden. (shrink)

This paper presents a nonmonotonic deontic logic based on commonsense entailment. It establishes criteria a successful account of obligation should satisfy, and develops a theory that satisfies them. The theory includes two conditional notions of prima facie obligation. One is constitutive; the other is epistemic, and follows nonmonotonically from the constitutive notion. The paper defines unconditional notions of prima facie obligation in terms of the conditional notions.

I extend theories of nonmonotonic reasoning to account for reasons allowing free choice. My approach works with a wide variety of approaches to nonmonotonic reasoning and explains the connection between reasons for kinds of action and reasons for actions or subkinds falling under them. I use an Anderson–Kanger reduction of reason statements, identifying key principles in the logic of reasons.

Free choice permission, a crucial test case concerning the semantics/ pragmatics boundary, usually receives a pragmatic treatment. But its pragmatic features follow from its semantics. We observe that free choice inferences are defeasible, and defend a semantics of free choice permission as strong permission expressed in terms of a modal conditional in a nonmonotonic logic.

I investigate substitutional interpretations of quantifiers that count existential sentences true just in case they have true instances in a parametric extension of the language. I devise a semantics meeting four criteria: (1) it accounts adequately for natural language quantification; (2) it provides an account of justification in abstract sciences; (3) it constitutes a continuous semantics for natural and formal languages; and (4) it is purely substitutional, containing no appeal to referential interpretations. The prospects for a purely substitutional theory of (...) quantification are thus no worse than for a referential account. (shrink)

In Acts 17, Paul offers general framework for demonstrating the existence of God—a supernatural being, a creator, designer, and ultimate purpose of the universe, who cannot be identified with anything natural but instead underlies and explains the natural world as a whole. What Paul says, combined with unstated theses about causation and explanation that his Stoic and Epicurean audience would have shared, adds up to a powerful argument for God’s existence. Cosmological and design arguments emerge as special cases.

In this paper I shall attempt to outline a nominalistic theory of mathematical truth. I call my theory nominalistic because it avoids a real (see [4]) ontological commitment to abstract entities. Traditionally, nominalists have found it difficult to justify any reference to infinite collections in mathematics. Even those who have tried to do so have typically restricted themselves to predicative and, thus, denumerable realms. I Indeed, many have linked impredicative definitions to platonism; nominalists have tended to agree with Weyl that (...) impredicative analysis is "a house built on sand" in a "logician's paradise."2 As a result, they have either worried about how much of mathematics empirical science requires (e.g., [34]) or renounced mathematical truth altogether (e.g., [12], [17]). My theory, in contrast, seeks a nominalistic interpretation of the entire body of classical mathematics. It tries to secure for the nominalist not merely the natural numbers but the reals, the ordinals, and inaccessible cardinals as well. If I am right, then nominalists can declare, with Goodman and Quine, that "any system that countenances abstract entities we deem unsatisfactory as a final philosophy" ([17],105), and, at the same time, with Hilbert, that "no one shall drive us out of the paradise which Cantor has created for us" ([20], 141). I cannot hope to convince you, in this small space, that my goal is fully achievable. Here I shall try to justify a smaller contention: that if we can explain our knowledge of logic (and of language generally), we can also explain our knowledge of mathematics. Given a nominalistic theory of logic, therefore, we can construct a nominalistic theory of mathematical truth. I shall thus argue for an epistemological thesis of logicism: any epistemology that suffices for our knowledge of logic also suffices for mathematics. (shrink)

This paper develops a metaphysically flexible theory of quantification broad enough to incorporate many distinct theories of objects. Quite different, mutually incompatible conceptions of the nature of objects and of reference find representation within it. Some conceptions yield classical first-order logic; some yield weaker logics. Yet others yield notions of validity that are proper extensions of classical logic.

Christine Korsgaard sees normative generalizations as provisionally universal, in the sense that exceptions to them have reasons for being exceptions and that they could in principle be revised into more specific and precise absolutely universal rules. Do exceptions to normative generalizations have such explanations? Can such generalizations always be revised into or replaced by absolutely universal rules? The answer depends on the structure of practical space, and, specifically, the degree to which normative relations are definable. Distinguishing degrees of definability in (...) practical space opens up paths for generalist and particularist conceptions of normativity. (shrink)

This study described the relationships between academic class and student moral sensitivity and reasoning and between curriculum design components for ethics education and student moral sensitivity and reasoning. The data were collected from freshman (n = 506) and senior students (n = 440) in eight baccalaureate nursing programs in South Korea by survey; the survey consisted of the Korean Moral Sensitivity Questionnaire and the Korean Defining Issues Test. The results showed that moral sensitivity scores in patient-oriented care and conflict were (...) higher in senior students than in freshman students. Furthermore, more hours of ethics content were associated with higher principled thinking scores of senior students. Nursing education in South Korea may have an impact on developing student moral sensitivity. Planned ethics content in nursing curricula is necessary to improve moral sensitivity and moral reasoning of students. (shrink)

Simple Logic succeeds in conveying the standard topics in introductory logic with easy-to-understand explanations of rules and methods, whilst featuring a multitude of interesting and relevant examples drawn from both literary texts and contemporary culture.

Conditionality is a modal feature (in only the trivial sense, in the case of the material conditional). For φ to be conditioned on ψ is for the appearance of φ and ψ to be connected in some way over some region of modal space.
