Passage Summary: Some people say everything we invent is a form of self-expression, but the author thinks that's a pointless thing to say because everything we do is self-expression, so the claim doesn't actually distinguish inventions from anything else.

Conclusion: We are not required to take the claim that all discoveries are self-expression seriously until a more meaningful version is presented.

Reasoning: The claim is trivial because it applies to literally every human action, making it uninformative.

Analysis: The author is essentially dismissing a theory because it is too broad to be useful. To strengthen this, we need a principle that justifies ignoring a claim just because it is 'trivially' true or universal. Look for an answer choice that links the 'triviality' or 'universal applicability' of a claim to its lack of merit or the lack of obligation to consider it. If a statement that applies to everything is inherently unworthy of serious debate, the author's dismissive stance is much more defensible.
