What is the difference between the truth of propositions and the validity of arguments?

In logic, truth is a property of statements, i.e. premises and conclusions, whereas validity is a property of the argument itself. If you talk of ‘valid premises’ or ‘true arguments’, then you are not using logical jargon correctly. True premises and a valid argument guarantee a true conclusion.

Truth is the complete accuracy of whatever was, is, or will be, error-proof, beyond doubt, dispute or debate, a final test of right or wrong of people’s ideas and beliefs. Validity is defined as the internal consistency of an argument.

How do you identify fallacies in an argument?

Here are my key take aways:

  1. Distinguish between rhetoric and logic. In logical arguments, it obviously matters whether your logic is right.
  2. Identify bad proofs. A bad proof can be a false comparison.
  3. Identify the wrong number of choices. This one is easy to spot.
  4. Identify disconnects between proof and conclusion.
