How can I tell if my argument is logically sound?
Ensure your premises are true and that they lead to your conclusion without logical fallacies. Test your argument by trying to find counterexamples or weaknesses in your reasoning.
What does it mean for an argument to "be logically sound"?
It means that the argument is valid (the conclusion follows from the premises) and that all the premises are true. If either condition fails, the argument is not "logically sound".
What are some alternatives to saying "be logically sound"?
You can use alternatives like "be logically valid", "be rationally coherent", or "be well-reasoned" to express a similar idea.
