counterpart theory

名詞

不可算名詞

(metaphysics) An alternative to standard possible worlds semantics in which an individual can exist in only one world, while other possible worlds contain (different) counterparts to that individual, and in which the modality operators (necessity, possibility) are replaced by quantifiers over possible worlds.

日本語の意味

（形而上学）個体が一つの世界にのみ存在し、他の可能世界ではその個体の異なる対応体（カウンターパート）が存在するという立場。ここでは必然性や可能性といったモダリティ・オペレーターの代わりに、各可能世界に対する量化が採用される理論。

In metaphysics, counterpart theory holds that an individual can exist in only one world while other possible worlds contain distinct counterparts to that individual, and that necessity and possibility are to be understood as quantification over possible worlds.

形而上学において、対応者理論は、個体が一つの世界でのみ存在し、他の可能な世界にはその個体の異なる対応者が存在し、必要性や可能性がこれらの世界に関する量化として理解されると主張する。

意味（1）

(metaphysics) An alternative to standard possible worlds semantics in which an individual can exist in only one world, while other possible worlds contain (different) counterparts to that individual, and in which the modality operators (necessity, possibility) are replaced by quantifiers over possible worlds.

If counterpart theory calls for the rejection of some popular modal principles, that needn't worry us. But if it forces us to reject principles of the logic of identity and quantification, that is more serious.
