Once a person has made some sort of stable, symbolic connection between two things, the connection will influence his subsequent behavior and will generate its own 'proof.' This is why it is idle and foolish to try to 'refute' religious, political, and similar beliefs with empirical arguments about referents that are symbols to the believer but not to the non-believer.

It is as if the Photograph always carries its referent with itself, both affected by the same amorous or funereal immobility, at the very heart of the moving world: they are glued together, limb by limb, like the condemned man and the corpse in certain tortures; or even like those pairs of fish (sharks, I think, according to Michelet) which navigate in convoy, as though united by an eternal coitus.
