Experience is a principle, which instructs me in the several conjunctions of objects for the past.

Habit is another principle, which determines me to expect the same for the future; and both of them conspiring to operate upon the imagination, make me form certain ideas in a more intense and lively manner, than others, which are not attended with the same advantages.

Without this quality, by which the mind enlivens some ideas beyond others (which seemingly is so trivial, and so little founded on reason) we coued never assent to any argument, nor carry our view beyond those few objects, which are present to our senses.

Nay, even to these objects we coued never attribute any existence, but what was dependent on the senses; and must comprehend them entirely in that succession of perceptions, which constitutes our self or person.

Nay farther, even with relation to that succession, we coued only admit of those perceptions, which are immediately present to our consciousness, nor coued those lively images, with which the memory presents us, be ever received as true pictures of past perceptions.
