Consider the following argument: “It’s wrong to drive in excess of the speed limit, even in a case where you’re rushing someone to the hospital to save their life. If everyone drove in excess of the speed limit, then that would make driving very dangerous for everyone, and we’d see a huge increase in traffic fatalities. So you should never drive in excess of the speed limit, no matter what.” Which of the following arguments could be used to refute the preceding argument by parallel reasoning:
A.
It’s wrong to lie even when an insane killer is asking you where you keep your guns. If everyone lied, then no one could ever trust what anyone else says, and we would lose the ability to share information through verbal exchange. So you should never lie under any circumstances.
B.
It’s wrong to hug and kiss your child, even when they ask you to do so. If everyone did that, then children would come to demand affection even when their parents are occupied and cannot offer affection. So you should never express affection to your child under any circumstances.
C.
It’s wrong to reply to your emails, even when they are urgent. If everyone always replied to all of the emails they receive, the total volume of email in the world would very soon swamp the total computational power of all of the world’s computers. So we should never reply to any of our emails.
D.
It’s wrong to eat potato chips, even when you want to. If everyone ate nothing but potato chips all the time, we would all be extremely malnourished, and the human species would soon die off. Therefore, you should never eat potato chips under any circumstances.
E.
(a) and (d) but not (b) or (c)
