Single Idea 15222

[filed under theme 9. Objects / E. Objects over Time / 2. Objects that Change ]

Full Idea

Some individuals to gain or lose certain capacities or powers, but do not thereby lose their identity. They still have the same nature. A drug, or photographic paper, may lose effectiveness over time.

Gist of Idea

Some individuals can gain or lose capacities or powers, without losing their identity

Source

Harré,R./Madden,E.H. (Causal Powers [1975], 1.II.C)

Book Ref

A Reaction

Damn! I thought I was the first to spot this problem! I, however, take it to be much more metaphysically significant than Harré and Madden do. The question is whether those properties were essential, since they can be lost. Essential but not necessary!

16159 For animate things, only the form, not the matter or properties, must persist through change [Aristotle, by Frede,M]
16173 Coming to be is by shape-change, addition, subtraction, composition or alteration [Aristotle]

15220 To say something remains the same but lacks its capacities and powers seems a contradiction [Harré/Madden]
15222 Some individuals can gain or lose capacities or powers, without losing their identity [Harré/Madden]
15296 A particular might change all of its characteristics, retaining mere numerical identity [Harré/Madden]

16193 'Adverbialism' explains change by saying an object has-at-some-time a given property [Hawley]

16202 The problem of change arises if there must be 'identity' of a thing over time [Hawley]
18930 Change is instantiation of a non-uniform distributional property, like 'being red-then-orange' [Cameron]
