@JLNobody,
Quote:Olivier, you are right: it is not possible to speak of changes where no objects are involved, but that is only with reference to speaking/thinking a language with its own internal (subject-predicate) logic and assuming that "objects" have some kind of solid essence rather than being events or processes. Your realism is far too naive (in the technical sense of naive realism) for anything but the most rigid and conventional of formulations.
I see. Your irrealism is far too thick to be even thinkable.
A process or event can be considered an object -- no difficulty here. "Essence" is a word I leave to those interested in theology and ontology. But solidity is an important characteristic of some objects, I think. That's why you can sit or lean on some objects, that's how you can use them as tools (a liquid screwdriver wouldn't work very well). Denying the solidity of some objects is much easier than actually vaporising them through that thought... Like passing through a solid wall is much harder than talking of the theoretical non-solidity of walls...
But of course, that's only a problem for the realists among us, who stupidly think that our world view should account for experience and facts.
