The doctrine of emanation is correctly described as of oriental origin.
They differ, however, fundamentally in this respect, that, whereas evolution regards the process as from the indeterminate lower towards the determinate higher, emanation regards it as from the highest to the indefinitely lower.
Plato, whose philosophy was strongly opposed to the evolution theory, distinctly inclines to the emanation idea in his doctrine that each particular thing is what it is in virtue of a pre-existent idea, and that the particulars are the lowest in the scale of existence, at the head of, or above, which is the idea of the good.
In 1901 Elster and Geitel found that a radioactive emanation is present in the atmosphere.
Edwards supposes in the nature of God an original disposition to an " emanation " of His being, and it is the excellency of this divine being, particularly in the elect, which is, in his view, the final cause and motive of the world.
