Reading the argument

Couldn't I want to help and want the credit?

Strip away the wordy opening. Wanting praise means wanting other people to think well of me. Deserving praise is a different question. The author gives us a requirement for deserving it: the action must be motivated by a desire to help others. That doesn't say a helpful motive is enough by itself, but it does say we need one.

Imagine I help an older person cross the street mostly because I want people to admire me. A smaller part of my motivation is that I actually want to help the person. The conclusion rules out praise because admiration is my primary goal. But I've still met the stated requirement of having a motive to help. That doesn't prove I deserve praise; it shows why the premise hasn't ruled me out.

What we’re looking for

To make the conclusion follow, I'd look for a rule that prevents these motives from coexisting. If wanting others' approval meant I couldn't also want to help, I would lack the motive the premise requires.

Working the answers

  • A
    Correct

    This supplies exactly that rule. A desire for others' favorable opinion cannot coexist with a desire to help. Someone acting primarily for praise has the first motive, so under A that person cannot also have the second.

    The premise requires a desire to help in order to deserve praise. A takes that required motive away from the person described in the conclusion. We can therefore say the person doesn't deserve praise for the aid. A is a strong rule, covering even actions only partly motivated by approval, but that is fine: the question asks for something that makes the conclusion follow.

  • B

    Solely means entirely. Primarily means mostly. The person in my example has mixed motives, with admiration as the main one. A rule disqualifying actions done entirely for praise doesn't cover that person. B leaves open precisely the case the argument needs to rule out.

  • C

    Wanting praise more than anything else doesn't establish indifference to other people's welfare. I might care about the person crossing the street even while caring more about the approving audience. C disqualifies people who don't care; it doesn't show that everyone acting primarily for praise belongs to that group.

  • D

    This concerns advancing interests, which describes what an action accomplishes. The premise concerns a desire to help, which describes why someone acts. Even if the aid advances both the helper's interests and another person's interests, D doesn't settle whether a mixed motive disqualifies the helper from praise. It gives another requirement without establishing that the person fails it.

  • E

    Saying motives determine whether praise is deserved doesn't tell us how to judge a mix of motives. We would still need a rule explaining why a main desire for approval cancels out a smaller desire to help. E doesn't provide one. Nor should we assume the original premise makes consequences entirely irrelevant: it gives a required motive, not a complete account of everything that could matter.
