3729. CONCERNING IDEAS. That man has ideas unknown to him, formed of [various] composites, and which are peculiar to everyone, may appear if one will call to mind cities, places, and other things [which he has witnessed]. Something [uniformly] occurs by which he distinguishes, by which he knows, whether it be taken from any particular place, or from anything seen, and [he will recollect] that he there met with something which impressed the idea somewhat deeply upon him. This fact takes precedence, but not the name or word; as, for instance, when thinking of Milan, the first thing that occurs, as being impressed upon him, is, that there men are often assassinated at night; when of Prague, that there are among the streets passage-ways through their houses for nocturnal homicides; when of the Jews there, that they covertly put Christians to death; and so of other places.
