"Our reasoning on this point, as on so many others, is in conformity with Hume´s. He, too, rejected the notion of a substantive ego on the ground that no such entity was observable. For, he said, whenever he entered most intimately into what he called himself, he always stumbled on some particular perception or other - of heat or cold, light or shade, love or hatred, pain or pleasure. He never could catch himself at any time without a perception. And this led him to assert that a self was 'nothing but a bundle or collection of different perceptions.'"
A. J. Ayer (1910-1989) british philosopher in Language, Truth and Logic
