Perdurance is a mode of persistence. The heart of perdurance is a space-time analogy: a perduring object is extended in time in a way that is analogous to how a composite object is extended in space. This paper is a discussion of perdurance in light of the distinction between mereologically structured and unstructured objects. I show that while the standard formulation of perdurance captures the space-time analogy for unstructured objects, it fails to capture the space-time analogy for temporally and spatially structured objects. I conclude that there are substantially different ways for an object to be space-like temporally extended.

持久性和结构

Perdurance是一种坚持的方式。持久性的核心是时空类比：持久性对象在时间上的扩展方式类似于复合对象在空间中的扩展方式。这篇论文是根据分体结构化对象和非结构化对象之间的区别来讨论持久性的。我表明，虽然持久性的标准表述捕捉到了非结构化对象的时空类比，但它未能捕捉到时间和空间结构化对象的时空类比。我的结论是，一个物体在时间上像空间一样扩展有多种不同的方式。
