Question

Correctly completed RAA refutations of an invalid arguments never

Answer 1

A RAA refutation of an invalid argument involves showing that the opposite conclusion leads to an absurd result, thus proving the original argument to be incorrect.

Step-by-step explanation:

A RAA refutation of an invalid argument involves showing that the opposite conclusion leads to an absurd or contradictory result, hence proving the original argument to be correct. To illustrate this, let's consider an invalid argument:

• Premise 1: All cats have wings.
• Premise 2: Fluffy is a cat.
• Conclusion: Fluffy has wings.

We can show that the opposite conclusion is absurd:

• Assume: Fluffy does not have wings.
• But: According to Premise 1, all cats have wings, so Fluffy should have wings.
• Therefore: The opposite conclusion leads to an absurd result.
• Therefore: The original conclusion that Fluffy has wings is incorrect.

By disproving the opposite conclusion, we can conclude that the original argument is invalid and its conclusion is incorrect.
