Examples

  • All of these cases illustrate the notion of parthood that forms the focus of mereology.

  • Still others take cases like this to motivate revisionary views about the nature of persistence, parthood, modality, identity, or existence.

    Material Constitution

  • Second, the extensionality principle is formulated in terms of a two-place parthood relation.

    Material Constitution

  • This is, for example, van Inwagen's (1990) view of the matter, which results in a fuzzification of parthood that parallels in many ways to the fuzzification of membership in Zadeh's (1965) set theory, and it is this sort of intuition that also led to the development of such formal theories as Polkowsky and Skowron's (1994) “rough mereology” or Smith's (2005) theory of

  • Others, such as Morreau (2002: 338), argue instead that the link between vague parthood and vague composition is unwarranted: perhaps the de re indeterminacy of (59) is inherited by some instances of

  • Ï (y, x) = 1, then x = y and one could argue that the very same conditions may be taken to fix the basic properties of parthood regardless of whether Ï is bivalent.

  • Clearly, the properties of such restricted relations may not coincide with those of parthood broadly understood, so the principles of mereology should not be expected to carry over automatically.

  • We conclude by briefly considering a question that is not directly related to specific mereological principles but, rather, to the underlying notion of parthood that mereology seeks to systematize.

  • On the other hand, one may wonder about the possibility of unordinary cases of symmetric parthood relationships.

  • Vice versa, one could frame a mereological theory by taking proper parthood as a primitive instead.
