Full Idea
The number of my perceptions which I can remember at any time always falls far short of the number of those which have actually occurred in my history, and those which I cannot remember are no less constitutive of my self than those which I can.
Gist of Idea
Personal identity is my perceptions, but not my memory, as I forget too much

A Reaction
Ayer is summarising Hume's criticism of Locke. It implies that Hume agrees with Locke on the 'consciousness' theory, which is a theory which should appeal to all empiricists. It is nonsense, though. I am not my awareness of some passing gnat.
