Famous quotes containing the words derek parfit, derek and/or parfit:
“It is not enough to ask, ‘Will my act harm other people?’ Even if the answer is No, my act may still be wrong, because of its effects on other people. I should ask, ‘Will my act be one of a set of acts that will together harm other people?’ The answer may be Yes. And the harm to others may be great. If this is so, I may be acting very wrongly, like the Harmless Torturers.”
—Derek Parfit (b. 1943)
“You must understand. Death must come to all. Sooner to some, later to others.”
—Tom Graeff. Derek (David Love)
“The Harmless Torturers. In the Bad Old Days, each torturer inflicted severe pain on one victim. Things have now changed. Each of the thousand torturers presses a button, thereby turning the switch once on each of the thousand instruments. The victims suffer the same severe pain. But none of the torturers makes any victim’s pain perceptibly worse.”
—Derek Parfit (b. 1943)
