The objects it presents are fixt and unalterable.

The impressions of the memory never change in any considerable degree; and each impression draws along with it a precise idea, which takes its place in the imagination as something solid and real, certain and invariable.

The thought is always determined to pass from the impression to the idea, and from that particular impression to that particular idea, without any choice or hesitation.
But not content with removing this objection, I shall endeavour to extract from it a proof of the present doctrine.

Contiguity and resemblance have an effect much inferior to causation; but still have some effect, and augment the conviction of any opinion, and the vivacity of any conception.

If this can be proved in several new instances, beside what we have already observed, it will be allowed no inconsiderable argument, that belief is nothing but a lively idea related to a present impression.
To begin with contiguity; it has been remarked among the Mahometans as well as Christians, that those pilgrims, who have seen MECCA or the HOLY LAND, are ever after more faithful and zealous believers, than those who have not had that advantage.
