The spontaneous memories which occasion regret are always those in which an opportunity was not seized, or perhaps not even perceived, due to an implicit prejudice, an unexamined idea. You become aware of such ideas not by their propositional content but by an emotional bow wave which serves as a red light to warn you away. You are vaguely aware of the idea, but what you give most heed to is the feeling that it is wrapped in. The functional map of your world which is drawn up by such implicit feelings is the one that you gave the most trust to, and this was not altogether wrong since it also contains your best intuitions about situations. The problem then was the contamination of the intuitive map by a set of derived prejudices, a reluctance to question certain notional values that were taken over from sources held to be authoritative, the segregation of certain ideas into forbidden zones. So much of what is argued about takes place in these intermediate regions where value and thought, loyalty to self and loyalty to groups are mixed together. This moral swamp is one of the strongest sources of the sense of sel in its most limiting form. Every destruction of parts of this complex is felt as light, relief, unprecedented liberation.
