Policy Adviser: Freedom of speech is not only a basic human right; it is also the only rational policy for this government to adopt.
Conclusion
Freedom of speech is the only rational policy for this government to adopt.
Evidence
Freedom of speech is a basic human right.
When ideas are openly aired, good ideas flourish, silly proposals are easily recognized as such, and dangerous ideas can be responded to by rational argument.
Nothing is ever gained by forcing citizens to disseminate their thoughts in secret.
Evaluate
This argument fits the Plan/Goal pattern, where the conclusion is recommending a policy (rational policy to adopt), implying that the goal is to create a society where good ideas can flourish, silly proposals are recognized, and dangerous ideas are countered rationally.
GIVEN freedom of speech's claimed benefits (flourishing of good ideas, recognition of silly proposals, rational responses to dangerous ideas), HOW COULD WE ARGUE that it is not the only rational policy for a government to adopt?
We must consider whether there are other factors or policies that might achieve similar outcomes, or if there are compelling reasons that might actually prevent freedom of speech from achieving these goals.
Goal
Let's find an answer that provides additional support for the idea that freedom of speech can bring about the desired results, or one that rules out the idea that other methods or policies could also do so.
