Sentence:  Now these plans, models, original patterns, existing in God's mind before He made a single plant or a single animal, are what we mean by <WSD>"Archetypes</WSD>". An <WSD>archetype</WSD>, therefore, is not a real, actual, objective thing, existing independent of the copy, or of God. It is only a plan, a model, an original pattern in God's mind—an idea, or thought of God. 
Meaning of the word marked with <WSD> tags:  An original model of which all other similar concepts, objects, or persons are merely copied, derivative, emulated, or patterned; a prototype. (from mid 16th c.)
