Some philosophers have argued that the open-endedness of the set concept has revisionary consequences for the semantics and logic of set theory. I consider (several variants of) an argument for this claim, premissed on the view that quantification in mathematics cannot outrun our conceptual abilities. The argument urges a non-standard semantics for set theory that allegedly sanctions a non-classical logic. I show that the views about quantification the argument relies on turn out to sanction a classical semantics and logic after all. More generally, this article constitutes a case study in whether the need to account for conceptual progress can ever motivate a revision of semantics or logic. I end by expressing skepticism about the prospects of a so-called non-proof-based justification for this kind of revisionism about set theory. 相似文献

The paper aims to develop a resemblance theory of properties that technically improves on past versions. The theory is based
on a comparative resemblance predicate. In combination with other resources, it solves the various technical problems besetting
resemblance nominalism. The paper’s second main aim is to indicate that previously proposed resemblance theories that solve
the technical problems, including the comparative theory, are nominalistically unacceptable and have controversial philosophical
commitments. 相似文献

Although the case for the judgment-dependence of many other domains has been pored over, surprisingly little attention has
been paid to mathematics and logic. This paper presents two dilemmas for a judgment-dependent account of these areas. First,
the extensionality-substantiality dilemma: in each case, either the judgment-dependent account is extensionally inadequate
or it cannot meet the substantiality condition (roughly: non-vacuous specification). Second, the extensionality-extremality
dilemma: in each case, either the judgment-dependent account is extensionally inadequate or it cannot meet the extremality
condition (roughly: absence of independent explanation). The paper concludes with a moral concerning the judgment-dependence
of a posteriori areas of discourse that emerges from consideration of these two a priori cases. 相似文献

The paper raises some difficulties for the typical motivations behind set reductionism, the view that sets are reducible to entities identified independently of set theory. 相似文献

I explain why Ross Cameron's definition of ultimate ontological basis is incorrect, and propose a different definition in terms of ontological dependence, as well as a definition of reality's fundamental layer. These new definitions cover the conceptual possibility that self-dependent entities exist. They also apply to different conceptions of the relation of ontological dependence. 相似文献
