The study of what makes an argument good or bad.

The study of what makes an argument good or bad is called Logic. Logic is a branch of philosophy that involves systematizing, defending, and critiquing arguments. In particular, logic plays a fundamental role in philosophy, because it helps philosophers construct and analyze their arguments.

Here are the steps to study it:

1. Understand the Basics of Logic: Logic is based on statements or propositions. A statement is a sentence that is either true or false. For example, "The sky is blue" is a statement.

2. Learn About Arguments: An argument in logic is a set of statements, one of which is the conclusion and the others are the premises. The premises are supposed to provide support for the conclusion.

3. Identify Good and Bad Arguments: A good argument is one where if the premises are true, then the conclusion must be true. This is known as a valid argument. A bad argument is one where it's possible for the premises to be true and the conclusion to be false.

4. Study Logical Fallacies: A logical fallacy is a mistake in reasoning. Studying these fallacies can help you avoid them in your own arguments and identify them in others' arguments.

5. Practice: Like any other skill, logic requires practice. Try analyzing arguments in books, articles, and even everyday conversations.

6. Take a Course or Read a Book on Logic: There are many resources available to learn more about logic, including college courses and books.

Remember, the goal of studying logic isn't to win arguments, but to seek truth and understanding.
