8607 | Supervenience is reduction without existence denials, ontological priorities, or translatability [Lewis] |
Full Idea: Supervenience is a stripped down form of reductionism, unencumbered by dubious denials of existence, claims of ontological priority, or claims of translatability. | |
From: David Lewis (New work for a theory of universals [1983], 'Dup,Sup,Div') | |
A reaction: Interesting. It implies that the honest reductionist (i.e. me) should begin by asserting supervience, and only at a second stage go on to deny a bit of existence, loudly affirm priorities, and offer translations. Honest toil. |
8606 | A supervenience thesis is a denial of independent variation [Lewis] |
Full Idea: A supervenience thesis is a denial of independent variation. | |
From: David Lewis (New work for a theory of universals [1983], 'Dup,Sup,Div') | |
A reaction: Not everyone agrees on this. This says if either A or B change, the change is reflected in the other one. But the other view is of one-way dependence. A only changes if B changes, but B can also make changes that don't affect A. |
