This paper challenges a standard interpretation according to which Frege's conception of logic (early and late) is at odds with the contemporary one, because on the latter's view logic is formal, while on Frege's view it is not, given that logic's subject matter is reality's most general features. I argue that Frege -- in Begriffsschrift -- retained the idea that logic is formal; Frege sees logic as providing the 'logical cement' that ties up together the contentful concepts of specific sciences, not the most general truths. Finally, I discuss how Frege conceives of the application of Begriffsschrift, and of its status as a 'lingua characteristica'. [ABSTRACT FROM AUTHOR]

Some philosophers (‘nihilists’) deny the existence of composite material objects. Other philosophers (‘universalists’) hold that whenever there are some things, they compose something. The purpose of this paper is to scrutinize an objection to these revisionary views: the objection that nihilism and universalism are both unacceptably uncharitable because each of them implies that a great deal of what we ordinarily believe is false. Our main business is to show how nihilism and universalism can be defended against the objection. A secondary point is that universalism is harder to defend than nihilism. [ABSTRACT FROM AUTHOR]

One of the most influential arguments in favour of perdurantism is the Argument from Vagueness. The argument proceeds in three stages: The first aims to establish atemporal universalism. The second presents a parallel argument in favour of universalism in the context of temporalized parthood (‘diachronic universalism’). The third argues that diachronic universalism entails perdurantism. I offer a novel objection to the argument. I show that on the correct way of formulating diachronic universalism the principle does not entail perdurantism. On the other hand, if diachronic universalism is formulated as Sider (incorrectly) proposes, the argument fails to establish his principle, and thus perdurantism. [ABSTRACT FROM PUBLISHER]
