Stimulus

Rhonda: As long as the cost is not too great, you should use your time, energy, or money to help others. People who are active participants in charitable causes have however prosperous the hermits may be.

Brad: You should ignore the problems of complete strangers and focus your generosity on your immediate relatives and close friends, since these are the people who will remember your when you yourself need help.

The question

Which one of the following principles, if valid, would most help to justify both Rhonda's

Answer choices, explained

  1. Bad Brad Match5% picked this

    One should always do what will produce the most benefit for

    This would help Rhonda argue that we should be charitable givers, but it doesn't really help Brad argue that we should help family/friends. Technically, neither person argued based on "maximizing benefit for others".

  2. Bad Rhonda Match5% picked this

    One should treat others as one expects to be treated

    Brad's argument consists of some reciprocity: you help them now, and they'll remember and help you out when you need it. Rhonda's, though, does not say you should give to others because they will give back to you. She says do it because it leads to a richer life.

  3. Correct78% picked this

    One should act in ways that will

    Why this is right

    What a silly-simple moral principle: if it helps you, do it. As we examined, the common ingredient of Brad and Rhonda's rationale was that the giver would stand to benefit (either by getting help later when they needed it or by living a richer life). So this principle helps both of them argue for their advice.

    Skill tested: Principle-Strengthen · how this choice captures the argument's function is the move to repeat next time.

  4. Bad Rhonda Match3% picked this

    One should make sacrifices for others only if they will eventually

    This aligns with Brad's thinking about our family/friends remembering what we did for them and returning the favor when we need it. But it contains nothing that has to do with Rhonda's "help others so that you'll have a richer life" argument.

  5. Bad Match For Both9% picked this

    One should always act in a manner that one can reflect

    Neither of them cite "do this, so that you can reflect with pride" as a basis for their advice.
