In this consists identity, when the ideas a thing is attributed to vary not at all from what they were at that moment, wherein we consider their former existence, and to which we compare the present.

A Reaction

Since we recognise that we might, in odd circumstances, have the identical idea while the object has been swapped, this is wrong. It sounds like the identity of indiscernibles. Identity is a concept applied to reality, not to ideas.


The 16 ideas with the same theme [general ideas about sameness of objects over time]:

Something must be unchanging to make recognition and knowledge possible [Aristotle on Parmenides]
Identity means that the idea of a thing remains the same over time [Locke]
Changeable accidents are modifications of unchanging essences [Leibniz]
A change more obviously destroys an identity if it is quick and observed [Hume]
Changing a part can change the whole, not absolutely, but by its proportion of the whole [Hume]
Continuity is needed for existence, otherwise we would say a thing existed after it ceased to exist [Reid]
An a priori principle of persistence anticipates all experience [Kant]
No one seems to know the identity conditions for a material object (or for people) over time [Kripke]
'What is it?' gives the kind, nature, persistence conditions and identity over time of a thing [Wiggins]
A thing 'perdures' if it has separate temporal parts, and 'endures' if it is wholly present at different times [Lewis]
If things change they become different - but then no one thing undergoes the change! [Gallois]
Gallois hoped to clarify identity through time, but seems to make talk of it impossible [Hawley on Gallois]
A continuous object might be a type, with instances at each time [Ladyman/Ross]
Most criteria for identity over time seem to leave two later objects identical to the earlier one [Cameron]
Endurance and perdurance just show the consequences of A or B series time [Ingthorsson]
Science suggests causal aspects of the constitution and persistance of objects [Ingthorsson]
