It is important here to distinguish between freely thinking and talking to ourselves psychologistically. Yes, both are cognitive, communicative and emotive behaviors.
However, when we are receptive to and coax our intelligence and responsiveness to take ourselves beyond our reflexive limitations, we are thinking freely.
By contrast, talking to ourselves psychologistically is a vicious circle, a self-confirming mental process that repeats, repeats and repeats. It references a mythologized time-space continuum in which we sense that we are apart from and know better than almost anyone else. It generates certainty and confidence in that which is inauthentic.
Usually, when this skewed image is contradicted, we are disappointed and angry but not at ourselves; instead we think of life as unfair or of others as opportunists or cheaters. Less often, though, we get a glimpse of the inauthenticity of the psychologistic know-it-all. It becomes apparent even to us that the self we had imagined does not have enough experience and substance to succeed in the real world. Then we may feel phony, embarrassed or shame-faced.
Still, as I said, a lopsidedly subjective display of the ego-function is self-confirming. Without an alternative approach to managing life and the attendant developmental effort, we may remain a prisoner of its disempowering parameters throughout our lives.
