Modal part/Simons: E.g. a class of counterparts might be considered as a whole with different modal components - modal parts: in various possible worlds.
Modality/Metaphysics/metaphysical/nature/necessity/Simons: a given atom could not have other particles - they are essential parts (components). - On the other hand: the given particles could have belonged to another atom. - It is not essential for them to be part of this atom. - "given"._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
