Philosophy Lexicon of Arguments

Parts, philosophy: in contrast to elements of a set, parts of a whole can stand in hierarchical relations. There may be dependencies, in particular ontological dependencies between parts and whole, as well as between parts of a whole, because parts may not exist if a questionable part does not exist. See also extrinsic, transitivity, reflexivity, symmetry, mereology, set theory, elements, order, overlap, dependency, ontological dependence.

Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments.

Schwarz I 34
Endurantism/Van Inwagen/Schwarz: e.g. caterpillar/butterfly: thesis: there is no insect, nothing that exists beyond the pupation.

Recombination/Mereology/Schwarz: the existence of temporal parts follows directly from the mereological universalism together with the rejection of the presentism. Then there are also e.g. aggregates from Socrates and Eiffel Tower (mereological sum) Socrates is a temporal part of it which at some point ceases to exist. Just as e.g. is a dried-out lake that however fills up again at the rainy season (Eiffel Tower).

Temporal Parts/van Inwagen: (van Inwagen 1981) van Inwagen basically rejects temporal parts.
SchwarzVsvan Inwagen: then he must radically limit the mereological universalism or be a presenter.
Perdurantism/Lewis/Schwarz: pleads for its contingency. Question/Schwarz: what should be contingent? Should there be possible worlds where the ordinary things have no temporal parts? Or should specific things be atomic in time and never change their form? Lewis seems to allow only the latter.

Schwarz I 34
Temporal Parts/Mereology/Schwarz: but if one accepts aggregates from Socrates and the Eiffel Tower, one could still deny that Socrates himself has temporal parts.
Lewis: does himself also not assert that necessarily everything that exists over time consists of temporal parts (1986f,x,1986e,205,1994 §1) VsStowe: temporal parts are not intended to provide an analysis of the enduring existence
Lewis: (1083d,76,similar Armstrong 1980,76): e.g. a child, Frieda1 suddenly disappears, while another child, Frieda2, suddenly appears. This may contradict the laws of nature, but it is logically possible.
Schwarz I 35
Perhaps no one notices anything. And there is nothing to notice.
Vs: this is not convincing.
EndurantismVs: cannot accept the premises
van InwagenVs: Frieda1 and Frieda2 cannot exist strung together, yet remain different. (2000,398)
