Lacan on the peculiarly human capacity to lie through telling the truth. Similarly, honesty as dishonesty:
He tells F. candidly about his recent romantic disappointment. He says how hurt he was, and not just hurt but stunned, as from a blow to the head. But he tells F. this only as a way of warding F. away, for he hopes that F. will be uncomfortable with such candour, such guardless intimacy, and therefore back off and give him more space. This space is what he desires, and the candour only serves to procure it. Unflinching honesty coincides with complete dishonesty. The open heart is a ring of barbed wire.
