Professor Hartley’s new book on moral philosophy contains numerous passages that can be found verbatim in an earlier published work by Hartley’s colleague, Professor Lawrence.
Conclusion
H has been dishonest is not acknowledging the intellectual debt owed to L. (i.e. H borrowed intellectual property from L)
Evidence
H's new book contains numerous passages that are found verbatim in L's earlier book. In H's book, these passages are not attributed to L.
Evaluate
We could use a Curious Fact / Explanation mindset for this, since the author is interpreting a curious matter.
Curious Fact Why are there passages in H's book that appeared earlier in L's book, but aren't attributed to L?
Author's Explanation H has taken these ideas from L and is now dishonestly presenting them as her own.
With this template, we think through two lenses: - could there be some Other Way to interpret this curious fact? - how plausible is the Author's Interpretation?
How else could we explain the verbatim passages that appear in both books? - Maybe H actually said this stuff first, and L stole it (perhaps L was just able to publish his book before H could publish hers)
- Maybe these passages are just from the Bible or from Kanye West, and so naturally they wouldn't be attributed to Lawrence, since they're not his words to begin with.
Goal
Since this is Necessary Assumption, look for an answer ruling out an alternate story for why both books contain identical passages, or look for an answer supplying an idea that would need to be true for the author's story of H stealing from L to be plausible.
