Class membership is not transitive, unlike being part of a part of the whole [Lesniewski, by George/Van Evra]
|
|
Full Idea:
Lesniewski distinguished the part-whole relationship from class membership. Membership is not transitive: if s is an element of t, and t of u, then s is not an element of u, whereas a part of a part is a part of the whole.

A reaction:
If I am a member of a sports club, and my club is a member of the league, I am not thereby a member of the league (so clubs are classes, not wholes). This distinction is clearly fairly crucial in ontology.

Davidson gave up reductive accounts of intention, and said it was a primitive [Davidson, by Wilson/Schpall]
|
|
Full Idea:
Later Davidson dropped his reductive treatment of intentions (in terms of 'pro-attitudes' and other beliefs), and accepted that intentions are irreducible, and distinct from pro-attitudes.

report of Donald Davidson (Intending [1978]) by Wilson,G/Schpall,S - Action 2
|
|
A reaction:
Only a philosopher would say that intentions cannot be reduced to something else. Since I have a very physicalist view of the mind, I incline to reduce them to powers and dispositions of physical matter.
