Philosophical Reasoning in Practice
Move beyond famous historical quotes and learn to wield the analytical tools philosophers use to evaluate claims. Dissect hidden premises, isolate moral intuitions, and systematically locate the root axioms behind intractable disagreements.
Like Duolingo, but for Philosophical Reasoning in Practice. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Deconstructing Everyday Claims and Navigating Disagreement and Deadlock. It assumes you already know the basics.

Key ideas in Philosophical Reasoning in Practice
- Hume's guillotine bars inferring an 'ought' purely from descriptive 'is' facts
- A biological or historical fact requires an explicit bridge premise to yield a moral duty
- Without an evaluative bridge premise, descriptive premises cannot reach a moral conclusion
- An enthymeme is a syllogism where one or more premises remain unstated
- Surfacing the suppressed premise lets you examine the underlying value judgment directly
- Rhetoric often hides controversial moral assumptions inside an enthymeme
- The naturalistic fallacy conflates being statistically common or evolved with being morally right
- Adaptive evolutionary traits like tribal aggression do not carry inherent ethical endorsement
- Acknowledging a natural hazard to protect human wellbeing does not equate nature with moral goodness
- Functional goodness refers to how effectively an agent or tool achieves a specific mechanical end
- Moral goodness evaluates the ethical justification of the goal and the action itself
- An action can display high instrumental skill while being completely morally wrong
- Standardizing an argument requires separating the descriptive observation from the moral principle
- The suppressed moral assumption forms the bridge premise connecting fact to conclusion
- Listing premises before the conclusion exposes exactly which claim must be defended
- Thought experiments work like laboratory controls by fixing background variables to isolate one principle
