It is widely held that free speech is a distinctive and privileged social kind. But what is free speech? In particular, is there any unified phenomenon that is both free speech and which is worthy of the special value traditionally attached to free speech? We argue that a descendent of the classic Millian justification of free speech is in fact a justification of a more general social condition; and, via an argument that 'free speech' names whatever natural social kind is justified by the best arguments, that free speech is therefore this more general condition. This condition involves not merely the orthodox freedom (in some sense) of speakers to distribute words, but also two less frequently acknowledged dimensions of free speech: audience understanding and consideration. We conclude with some discussion of the policy implications of this conception of free speech.

This paper proffers an account of why interdisciplinary research on, inter alia, the nature of time can be fruitful even if the disciplines in question have different explanatory pro-jects. We suggest that the special sciences perform a subject setting role for lower-level disciplines such as physics. In essence, they tell us where, amongst a theory of the physical world, we should expect to locate phenomena such as temporality; they tell us what it would take for there to be time. Physical theory tells us whether there is anything like that in the world and what its hidden nature is. Only working in tandem can physics and the special sciences locate and describe the phenomenon that is time.

that there is something rationally or conceptually defective in judging that an act is right without being in any way motivated towards it—is one which has tended to lead either to error theories of ethics on the one hand, or acceptance of the truth of internalism on the other. This paper argues that it does play a kind of subject-setting role, but that our responses to cases can be rationalised without requiring that internalism is true for ethical realism to be vindicated. Instead what is required is that something like internalism be believed to be true. The widespreadness of the internalist intuition is part of what makes it the case that some actions are right and others wrong. Of course these beliefs might be false—as the present author holds—consistent with ethical realism, just so long as they are widely held, and whatever else it takes to vindicate realism is the case. In such a situation, widespread false belief would be part of what makes it so that some acts are right, and others wrong.

This paper identifies problems with indexicalism and abverbialism about temporary intrinsic properties, and solves them by disentangling two senses in which a particular may possess a property simpliciter. The first sense is the one identified by adverbialists in which a particular possesses at all times the property as a matter of foundational metaphysical fact regardless of whether it is manifest. The second involves building on adverbialism to produce a semantics for property-manifestation according to which different members of a family of second-order properties of the foundational property are relevant to property manifestation at different times.
