At The New Republic, Steven Pinker eviscerates the right’s rubric for opposing biomedical research.

The problem is that “dignity” is a squishy, subjective notion, hardly up to the heavyweight moral demands assigned to it. The bioethicist Ruth Macklin, who had been fed up with loose talk about dignity intended to squelch research and therapy, threw down the gauntlet in a 2003 editorial, “Dignity Is a Useless Concept.” Macklin argued that bioethics has done just fine with the principle of personal autonomy–the idea that, because all humans have the same minimum capacity to suffer, prosper, reason, and choose, no human has the right to impinge on the life, body, or freedom of another.
