Abstract

Dicephalus conjoined twins, conjoined twins fused below the neck, pose a unique problem for animalism, the view that each of us is identical to a living human organism. If dicephalus twins are, or share, the same human organism, then at least some of us are not numerically identical to living human organisms. Some animalists have responded by arguing that dicephalus twins are numerically distinct but overlapping human organisms. Another option is to say that dicephalus twins are merely conjoined: they are intimately connected with one another, but they do not overlap or share any of their parts. In this paper, I argue that there are both metaphysical and practical or ethical considerations that weigh in favor of the non-overlapping option. Animalists who already have good reason to think that there are two living human organisms in a case of dicephalus twins should prefer the non-overlapping option to the overlapping option.

连体双胞胎没有相同的器官

双头连体双胞胎，颈部以下的连体双胞胎，给动物主义带来了一个独特的问题，即我们每个人都与活着的人类有机体完全相同。如果双头双胞胎是，或者共享相同的人类有机体，那么至少我们中的一些人在数字上与活着的人类有机体不相同。一些动物学家对此的回应是，双头双胞胎在数字上是不同的，但它们是重叠的人类有机体。另一种说法是，双头双胞胎仅仅是连体：它们彼此紧密相连，但它们没有重叠或共享任何身体部位。在本文中，我认为有形而上学和实践或伦理的考虑，有利于不重叠的选择。动物学家已经有充分的理由认为，在双头双胞胎的情况下，有两个活的人类有机体，他们应该更喜欢不重叠的选项，而不是重叠的选项。

期刊介绍： Philosophical Studies was founded in 1950 by Herbert Feigl and Wilfrid Sellars to provide a periodical dedicated to work in analytic philosophy. The journal remains devoted to the publication of papers in exclusively analytic philosophy. Papers applying formal techniques to philosophical problems are welcome. The principal aim is to publish articles that are models of clarity and precision in dealing with significant philosophical issues. It is intended that readers of the journal will be kept abreast of the central issues and problems of contemporary analytic philosophy. Double-blind review procedure The journal follows a double-blind reviewing procedure. Authors are therefore requested to place their name and affiliation on a separate page. Self-identifying citations and references in the article text should either be avoided or left blank when manuscripts are first submitted. Authors are responsible for reinserting self-identifying citations and references when manuscripts are prepared for final submission.
