The Art of Clear Thinking
Like Duolingo, but for The Art of Clear Thinking. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 9 levels across 2 sections, about 18 minutes end to end, roughly 4 days at five minutes a day. It moves through Building and Breaking Arguments and The Logic Engine. It starts from scratch.

Key ideas in The Art of Clear Thinking
- An argument requires a claim (conclusion) and evidence (premises)
- Premises act as the foundation or support
- Stating a contrary opinion without support is not an argument
- The conclusion is the 'destination' of the logic
- Arguments are structured to persuade through reasoning
- The relationship between the two is what creates the argument's structure
- Distinguishing between a logical argument and a mere disagreement
- Identifying the functional roles of premises and conclusions
- Validity only measures if the conclusion follows from the premises
- A valid structure ensures that IF the premises were true, the conclusion would have to be true
- Logic can be applied to hypothetical or fictional scenarios
- An argument can have a perfect logical flow (validity) but be based on false information
- A 'sound' argument requires both a valid structure and true premises
- Most everyday arguments leave out 'obvious' steps that are necessary for the logic to work
- Hidden premises are the unstated beliefs that connect a reason to a claim
- An argument can have a perfect logical flow but be based on false information
