But I think “equality” and “identity” are being conflated in this discussion. Identity leads to unanswerables like the Ship of Theseus. Equality (or even approximate equality where that is well-defined) is more tractable and often what we are really interested in. Best wishes, -wReceived on Thursday, 29 November 2018 17:57:31 UTC
