Today I started the course Introduction to Logic, at the Tom Wood’s Liberty Classroom.
Here I’m sharing the notes I took, and what I learned:
- Aristotle hit upon the idea that the goodness or badness of arguments is independent of their content.
- There is a small number of types of arguments that are good.
- When arguments are simple and their subjects uncontroversial, most people get it right. When they become complex (by introducing semantic complexity, or negations) and/or when the subject matter of the argument is controversial, our native intuitions are prone to error.
- The heart of logic is inference.
- Logic is first and foremost, the study of formal argumentation.
- It’s called formal argumentation because it focuses on the form or structure of the argument, rather than on its content (Aristotelian logic).
- Formal logic is very powerful, but it’s only part of a wider context for argumentation.
To answer the question of who needs logic. Gerard Casey puts it in one simple sentence: Anyone who wants to think straight and argue well.
