Primitive. Descriptive of the original, or undifferentiated, human psyche. (See also archaic.)
I use the term “primitive” in the sense of “primordial,” and . . . do not imply any kind of value judgment. Also, when I speak of a “vestige” of a primitive state, I no not necessarily mean that this state will sooner or later come to an end. On the contrary, I see no reason why it should not endure as long as humanity lasts.[“A Review of the Complex Theory,”CW8, par. 218.]
