"Once upon a time, scientific advance was slapped upon the stall from which the customer did or did not pick it up; nobody, it was then understood, would be forced to avail himself of X-ray or penicillin, just as nobody will ever be forced to accept an organ transplant.

Fine. Go ahead. Die. See if I care."
