An exploration of timeless philosophical issues about persistence, change, time and sameness. Gallois offers a critical survey of various rival views and puts forward his own theory: that it is coherent and helpful to suppose that things can be identical at one time, but distinct at another.

The book is well-organised and clearly written ... Gallois is very clever and ingenious in his defence of the Occasional Identity Thesis and is broadly fair to his opponents, about whose positions he is well-informed. His arguments are rigorous and well-constructed and his mastery of some tricky points of logic is impressive.

Klappentext

Occasions of Identity is an exploration of timeless philosophical issues about persistence, change, time, and sameness. Andre Gallois offers a critical survey of various rival views about the nature of identity and change, and puts forward his own original theory. He supports the idea of occasional identities, arguing that it is coherent and helpful to suppose that things can be identical at one time but distinct at another. Gallois defends this view, demonstrating how it can solve puzzles about persistence dating back to the Ancient Greeks, and investigates the metaphysical consequences of rejecting the necessity and eternity of identities.
