Freud’s thinking was dynamic and dialectical. I think you’re acknowledging that when you say he has to be taken as a whole. There are parts of that whole that are inconsistent, parts that were added and removed, a ship of Theseus grand theory of personality. His seduction theory is a good example of the dialectical aspect of his theorizing, but there are many others. So I agree, it is the process that describes the Freudian “analytic” approach, moreso than a specific construct or summation of his theory (theories?) as it (they) existed at any particular point during or after his lifetime.
