"Anxiety about what a text omits is finally an anxiety about figurative language: does a metaphor repress the thing to which it refers or is it the means by which repression is subverted?"
James Longenbach. The Resistance to Poetry.
Maybe some things can only be faced obliquely, symbolically, by substitution. I read the following on the Wikipedia page "Ego-syntonic and ego-dystonic":
"Later psychoanalytic writers emphasized how direct expression of the repressed was ego-dystonic [refers to thoughts and behaviors in conflict with a person's ideal self image], and indirect expression more ego-syntonic [consistent with a person's ideal self image]."
Both fragments seem to be part of the same conversation.
