I never can catch myself at any time without a perception, and never can observe any thing but the perception.

When my perceptions are removed for any time, as by sound sleep; so long am I insensible of myself, and may truly be said not to exist.

And were all my perceptions removed by death, and coued I neither think, nor feel, nor see, nor love, nor hate after the dissolution of my body, I should be entirely annihilated, nor do I conceive what is farther requisite to make me a perfect non-entity.

If any one, upon serious and unprejudiced reflection thinks he has a different notion of himself, I must confess I call reason no longer with him.

All I can allow him is, that he may be in the right as well as I, and that we are essentially different in this particular.
