Good and bad reasoning

An explanation of good and bad reasoning.

An argument is good if it succeeds logically (that’s what we learnt last week) and if the premises are true. Otherwise, it’s bad.

By the end of the week, you will be able to evaluate arguments as being good or bad. In particular, we will help you to:

  • Create and use counter examples to show that arguments are invalid or weak.

  • Identify irrelevant premises.

  • Distinguish between sound and cogent arguments.

  • Evaluate arguments as being good or bad.
