The rationality of individual agents is secured for the most part by their make-up or design. Some agents, however – in particular, human beings – rely on the intentional exercise of thinking or reasoning in order to promote their rationality further; this is the activity that is classically exemplified in Rodin’s sculpture of Le Penseur. Do group agents have to rely on reasoning in order to maintain a rational profile? Recent results in the theory of judgment aggregation show that under a range of plausible conditions they do. In a slogan: group agents are made, not born.

Modal functionalism is the view that talk about possible worlds should be construed as talk about fictional objects. The version of modal fictionalism originally presented by Gideon Rosen adopted a simple prefixing strategy for fictionalising possible worlds analyses of modal propositions. However, Stuart Brock and Rosen himself in a later article have independently advanced an objection that shows that the prefixing strategy cannot serve fictionalist purposes. In this paper we defend fictionalism about possible worlds by showing that there are other strategies besides the prefixing strategy for fictionalising talk about possible worlds, and that these strategies are proof against the objection advanced by Brock and Rosen

As the first ontologist, Parmenides has a special place in the history of philosophy, not only because of his originality, but also because of the greatness of his particular attempt in the philosophy of being. His stature is such that any later attempt in the inquiry into being must measure itself against his achievement. His famous philosophical poem, which we have in fragments, is a permanent challenge to later philosophers. Thus Plato could describe Parmenides as ‘a man to be respected and at the same time feared’. And in our own day Martin Heidegger has said that.

This essay emerges from consideration of a question in the epistemology of ethics or morality. This is not the common claim-centered question as to how moral claims are confirmed and whether their mode of confirmation gives us grounds to be confident about the prospects for ethical discourse. Instead, I am concerned with the less frequently posed concept-centered question of where in human experience moral terms or concepts are grounded — that is, where in experience the moral becomes salient to us. This question was central to moral epistemology in the form it took among thinkers such as Locke, Hume, and Kant, and it remains of the first importance today

Philosophy can serve two roles in relation to moral thinking: first, to provide a meta-ethical commentary on the nature of moral thought, as the methodology or the philosophy of science provides a commentary on the nature of scientific thought; and second, to build on the common presumptions deployed in people's moral thinking about moral issues, looking for a substantive moral theory that they might support. The present essay addresses the nature of this second role; illustrates it with substantive theories that equate moral obligations respectively with requirements of nature, self-interest, benevolence, reason and justifiability; and outlines a novel competitor in which the focus is shifted to requirements of co-reasoning and respect

Taken as a model for how groups should make collective judgments and decisions, the ideal of deliberative democracy is inherently ambiguous. Consider the idealised case where it is agreed on all sides that a certain conclusion should be endorsed if and only if certain premises are admitted. Does deliberative democracy recommend that members of the group debate the premises and then individually vote, in the light of that debate, on whether or not to support the conclusion? Or does it recommend that members individually vote on the premises, and then let their commitment to the conclusion be settled by whether or not the group endorses the required premises? Deliberative-democratic theory has not addressed this issue, and this is a problem. The discursive dilemma of my title--a generalisation of the doctrinal paradox from analytical jurisprudence--shows that the procedures distinguished can come apart. Thus deliberative democrats must make up their minds on where they stand in relation to the issue; they cannot sit on the fence. This paper is an attempt to address the issue and look at the grounds on which it may be resolved.

Group agents have been represented as expressive fictions by those who treat ascriptions of agency to groups as metaphorical; as pragmatic fictions by those who think that the agency ascribed to groups belongs in the first place to a distinct individual or set of individuals; and as theoretical fictions by those who think that postulating group agents serves no indispensable role in our theory of the social world. This paper identifies, criticizes and rejects each of these views, defending a strong realist position
