317. [309.] Unless one acquires for himself a concept of these two kinds of degrees, he cannot have an idea of the inner and outer elements in a person, thus neither an idea of the soul and body, and not even one of cause and effect.

Nor can he have any idea of correspondences, representations, influx, order, thus any idea of those matters which have to do with order, both in the natural world and in the spiritual world, thus scarcely a correct idea of anything.
