The transference is more than projection, being something archetypal, unconscious, and metaphorical, and as such represents phenomena and processes. The positive and negative projections only give it their appearance and sign. Because it transcends them, the term transference can legitimately be distinguished from the term projection, and used to designate the successive stages of the individuation process as it occurs in relation to the analyst.... Projections are aids to the "work," they reflect it but are not to be identified with it, and so the transference of the individuation process goes on behind, or one could also say within, them.
— Edward F. Edinger
Edinger is marking a distinction that psychotherapy routinely collapses. The ordinary clinical understanding of transference treats it as a matter of misdirected feeling — you see your father in the analyst, the analyst holds your hunger for the mother, and the work consists of gradually withdrawing those projections until the other person becomes merely themselves. That is not wrong, but it is partial. What Edinger points to is the process running beneath the projections, using them the way a river uses its banks — shaped by them, visible through them, but not reducible to them.
The individuation process needs a vessel, and the analytical relationship furnishes one. The projections — idealization, rage, longing, dependency — are not the goal, nor are they simply obstacles. They are the medium through which something impersonal moves toward articulation. Strip away every charged feeling about the analyst and you have not arrived at truth; you have simply removed the scaffolding before the structure can bear its own weight. The transference, in Edinger's sense, is how the psyche stages its own drama at a specific moment in a specific life. The projection is the costume. What wears it is harder to name and does not disappear when the costume is finally laid aside.
