Single Idea 13182
[filed under theme 9. Objects / E. Objects over Time / 1. Objects over Time
]
Full Idea
Everything accidental or changeable ought to be a modification of something essential or perpetual.
Gist of Idea
Changeable accidents are modifications of unchanging essences
Source
Gottfried Leibniz (Letters to Burcher De Volder [1706], 1704.06.30)
Book Ref
Leibniz,Gottfried: 'Philosophical Essays', ed/tr. Arlew,R /Garber,D [Hackett 1989], p.180
A Reaction
Clear evidence that Leibniz is very much a traditional Aristotelian essentialist, and not as modal logicians tend to characterise him, as a super-essentialist who thinks all properties are essential. They are necessary for identity, but that's different.
