Introduction to Philosophy

 

'When I enter most intimately into what I call myself, I also stumble on some particular perception or other ... I can never catch myself at any time without a perception ... If anyone upon serious and unprejudiced reflection, thinks he has a different notion of himself, I must confess I can no longer reason with him. He may perhaps, perceive something simple and continu'd, which he calls himself; tho' I am certain there is no such principle in me.' Hume Treatise Book I Section VI.
