Anscombe thought that practical knowledge – a person’s knowledge of what she is intentionally doing – displays formal differences to ordinary empirical, or ‘speculative’, knowledge. I suggest these differences rest on the fact that practical knowledge involves intention analogously to how speculative knowledge involves belief. But this claim conflicts with the standard conception of knowledge, according to which knowledge is an inherently belief-involving phenomenon. Building on John Hyman’s account of knowledge as the ability to use a fact as a reason, I develop an alternative, two-tier, epistemology which allows that knowledge might really come in a belief-involving and an intention-involving form.

Two ideas shape the epistemology of testimony. One is that testimony provides a unique kind of knowledge. The other is that testimonial knowledge is a social achievement. In traditional terms, those who affirm these ideas are anti-reductionists, and those who deny them are reductionists. There is increasing interest, however, in the possibility of affirming these ideas without embracing anti-reductionism. Thus, Sanford Goldberg uses the idea of epistemic buck-passing to argue that even reductionists can accept the uniqueness of testimonial knowledge, and Jennifer Lackey gives both speaker and hearer an essential role in testimonial justification, rejecting both reductionism and anti-reductionism in favor of what she calls dualism. After distinguishing a weaker and a stronger notion of buck-passing, we show how anti-reductionists can use the stronger notion to motivate their position, and to answer Goldberg’s and Lackey’s challenges.

Since Benacerraf’s ‘What Numbers Could Not Be, ’ there has been a growing interest in mathematical structuralism. An influential form of mathematical structuralism, modal structuralism, uses logical possibility and second order logic to provide paraphrases of mathematical statements which don’t quantify over mathematical objects. These modal structuralist paraphrases are a useful tool for nominalists and realists alike. But their use of second order logic and quantification into the logical possibility operator raises concerns. In this paper, I show that the work of both these elements can be done by a single natural generalization of the logical possibility operator.

Intention Cognitivism – the doctrine that intending to V entails, or even consists in, believing that one will V – is an important position with potentially wide-ranging implications, such as a revisionary understanding of practical reason, and a vindicating explanation of ‘Practical Knowledge.’ In this paper, I critically examine the standard arguments adduced in support of IC, including arguments from the parity of expression of intention and belief; from the ability to plan around one’s intention; and from the explanation provided by the thesis for our knowledge of our intentional acts. I conclude that none of these arguments are compelling, and therefore that no good reason has been given to accept IC.

The movement of people across borders is one of the most pressing issues of our time. Yet it is still unclear how migration should be regulated to be fair to the sending societies, the host societies and the individual migrant. What is at issue? Are we discussing migration from an ethical or from a political philosophical perspective, or both? Are we discussing migration from a global justice perspective or social justice perspective? Do we consider political legitimacy and democratic self-determination as part of our analysis? How should we balance demands of justice in immigration compared to those of emigration?

The debate concerning the ontological status of musical works is perhaps the most animated debate in contemporary analytic philosophy of music. In my view, progress requires a piecemeal approach. So in this article I hone in on one particular musical work concept – that of the classical Western art musical work; that is, the work concept that regulates classical art-musical practice. I defend a fictionalist analysis – a strategy recently suggested by Andrew Kania as potentially fruitful – and I develop a version of such an analysis in line with a broad commitment to philosophical naturalism.

It is a central tenet of ethical intuitionism as defended by W. D. Ross and others that moral theory should reflect the convictions of mature moral agents. Hence, intuitionism is plausible to the extent that it corresponds to our well-considered moral judgments. After arguing for this claim, I discuss whether intuitionists offer an empirically adequate account of our moral obligations. I do this by applying recent empirical research by John Mikhail that is based on the idea of a universal moral grammar to a number of claims implicit in W. D. Ross’s normative theory. I argue that the results at least partly vindicate intuitionism.
