To lie about subjective truths: that is the easiest kind of lie to pull off, and it has the deepest and most devastating consequences. The denial of the existence of something shared and precious – and precious for the very fact that it was shared – is to die alive. To die this death, but then to return to life and to trust again is pure recklessness.
Can you provide an example?
I’m talking about emotional revisionism. A really common example is projecting a momentary negative feeling back through an entire relationship, and characterizing the relationship itself as negative. Sometimes it is done narratively, where something which was experienced immediately, repeatedly and unmistakably as good is nullified with a new explanation or framing, usually when the nullification is morally convenient.
