I don't read pasted Wiki stuff from people who are too lazy to write their own summary. Never heard of Groening, and if somebody who knows about them both finds resemblances to Cayce, I'll take their word for it.

Jacques Lacan seems to have had a similar success record to Caycean spiritualism in its therapeutic dimension. Psychoanalysis in general has had no great unambiguous triumphs, but Lacan seems to have built his towering monument of gibberish on top of a mountain of corpses. He totally failed to help anybody.
