The unconscious as "inside"

Freud and others have shown that there's an "inside" to actions, feelings, motivation, and thinking. No one can seriously doubt that this is so. However, since then being that we have rightly used the term "unconscious" as an adjective put before these nouns, some have inadvertently made a valuable concept into something like a definite fact. To my mind, this well-proven inference – that there is an "inside" – becomes confused with fact, because now there is 1) knowledge about the different ways in which these phenomena of behavior and symptom manifest and also 2) these rhetorical forms have led to the discovery of therapies that may be used to clinical benefit.
