Essayist: The existence of a moral order in the universe—i.e., an order in which bad is always eventually punished and good rewarded—depends upon human souls being immortal.

Conclusion (it follows that)

If human souls are immortal, the bad will be punished (regardless of how the moral order is represented).

Evidence

The existence of a moral order depends upon human souls being immortal.

Evaluate

This argument is really hard to understand. We omitted the 2nd sentence from the reasoning core, because it's just providing inessential examples of how different moral orders handle the idea of the good being punished and the bad rewarded (this moral order thinks that cosmic justice is achieved via reincarnation/karma, while that moral order thinks that cosmic justice is achieved via a supreme being in an afterlife).

Since those are just two of possibly many examples, neither is crucial to the reasoning.

What we're left with feels a bit like a circular argument. Both the first sentence and the last (i.e. the premise and the conclusion) are talking about moral order / immortal souls / bad punished.

So is the premise just restating the conclusion (as we see in Circular arguments).

On the other hand, both the first / last sentence have conditional logic indicator words: "depends" and "if". Whenever we're doing Flaw and see conditional logic, we immediately worry about Necessary vs. Sufficient flaws (i.e. illegal reversals or negations).

So let's diagram these to see whether they're replicas of each other, in which case we should be thinking Circular, or whether they're an illegal reversal/negation of each other, in which case we should be thinking Nec vs. Suff.

The first sentence is saying "X depends on Y", which is the same as "X requires Y", which is diagrammed X→Y.

Moral Order immortal (where good rewarded → human souls and bad punished)

The last sentence uses "if", which is a sufficient trigger.

immortal human souls → bad punished

Goal

Okay, it's not a restatement, so it's not Circular. It's also not exactly an illegal reversal, but it's pretty close to that.

The first conditional had "bad punished" on the left and "immortal souls" on the right, and the second conditional has those two appearing on opposite sides.

So let's look for something like Necessary vs. Sufficient flaw, something addressing this weird switch.

23.

Which one of the following most accurately describes a flaw in the essayist's reasoning?

  1. Correct

    From the assertion that something

    Why this is right

    This has the form, "From the assertion that X, the argument concludes Y", so we would want to check on whether X matches evidence and Y matches conclusion. Did the evidence contain an assertion that something is necessary to a moral order? Yes, the first sentence says that a moral order requires "human souls being immortal". Does the conclusion act like "human souls being immortal" is sufficient for an element of the moral order to be realized? The conclusion acts like "human souls being immortal" is sufficient to prove that "the bad will be punished". Was "the bad will be punished" an element of the moral order? Yes! The first sentence defines "moral order" as something that includes the element of the bad being punished. Since this answer descriptively matches and seems to describe the funky conditional reversal we spotted, this looks good.

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

  2. The argument takes mere beliefs

    Trap

    Not Opinion vs. Fact Bad Evidence Match This answer describes a semi-famous Flaw we call Opinion vs. Fact, which is when the author treats opinion as fact. That would feel like this: Ben thinks that Marcy's drawing is political. Since no political drawings are allowed in the Spring Fair, Marcy's drawing won't be allowed in the Spring Fair. That argument is flawed by treating Ben's opinion as though it's a fact. This argument we read has nothing like that. The 2nd sentence talks about different belief systems, but the author never establishes reincarnation or supreme being as facts. The author's conclusion is trying to establish the fact that, "if human souls are immortal, then the bad will be punished". Did the premise say, "some people believe that if human souls are immortal, then the bad will be punished?" No. The author isn't leaning on any premise about people's beliefs. She's leaning on the premise in the first sentence.

  3. From the claim that the

    Bad Evidence / Conclusion Match

    This has the form, "From the claim that X, the argument concludes Y", so we would want to check on whether X matches evidence and Y matches conclusion. Did the evidence claim that "the immortality of human souls implies a moral order in the universe"? No. The evidence said the converse. "The existence of a moral order implies the immortality of human souls". We could stop reading there, since that's grounds for elimination. But the conclusion half of this answer also doesn't match. According to this answer, the conclusion says that "a moral order implies that human souls are immortal", whereas the conclusion actually says that "human souls being immortal implies that the bad will be punished".

  4. The argument treats two fundamentally

    Out of Scope: treats as same

    The author does not consider karma/reincarnation to be the same as supreme being who metes out justice. The author is introducing those as variations on the idea of a moral order. But the conclusion acknowledges their distinctiveness by saying "however you want to represent a moral order ... whether it's the reincarnation way or the supreme being way ... my conclusion follows". If by "essentially the same", we're saying the author treats reincarnation and supreme being as essentially the same, because they're both moral orders in which the bad are punished and the good are rewarded, that's fine. We could say, "Yes, that's true, the author did do that. But we don't find anything objectionable about that." We're not complaining about the author's reasoning by saying "he considered these two different belief systems to be similar insofar as they are moral orders in which the bad are punished and good are rewarded".

  5. The argument’s conclusion is presupposed

    Not Circular

    When we see language like, "the premise restates the conclusion" or "the premise assumes the truth of the conclusion", that means Circular reasoning. We know that Circular Reasoning is almost always wrong, so we would never "guess" it's circular. We'd be safer guessing elsewhere. Had the final sentence really been a restatement of the first sentence, then we'd pick this answer. But the final sentence was a different claim, so it's not circular.
