One of the major complaints about lobotomy, back when it was being performed, was that you couldn't turn it off. Once you were lobotomized, there it was, you were lobotomized forever, though the effects might diminish over time as severed neural connections reestablished themselves. (Meaning that your crazy could grow back too, assuming lobotomy had done anything to diminish it, whereupon some people got a second one -- repeat customers!) But Walter Freeman had a rebuttal for this as for every criticism ever launched against his pet procedure (often the maddening and not always inaccurate "You're just jealous because I'm a famous doctor and you're not"): that lobotomy was irrevocable, he said, was the whole point. The patient can decide not to show up for talk therapy, he can chuck his Thorazine out the window, but he can't fail to comply with having had a lobotomy.
