Learn, practise, explain
Try the exercise before reading its explanation. Answer the self-check questions in your own words, then compare your reasoning with the answers. Revisit any difficult section before moving on. No account or payment is needed.

Asking philosophical questions
When friends disagree about success, fairness or a good life, they may be using the same word for different ideas. Philosophy makes those ideas visible and examines the reasons behind them. You need curiosity and everyday examples, not previous study of a philosophical tradition.
Learning outcome: Turn a broad disagreement into a precise question, distinguish different kinds of inquiry, and improve an answer through a counterexample.

Logic, arguments and fallacies
An argument is more than a disagreement. It is a set of reasons offered for a conclusion. This lesson begins with ordinary sentences, so no algebra or previous philosophy is required. You will learn to inspect the connection between reasons and conclusions, including a contribution from the Indian Nyaya tradition.
Learning outcome: Map an argument, test a conditional claim, distinguish deduction from induction, and repair common errors without attacking the speaker.

Ethics: duty, consequences and character
Ethical decisions ask what we ought to do and why. They can involve competing responsibilities even when nobody intends harm. First understand how to identify a claim and its reasons, as taught in the introductory philosophy and logic lessons. Then compare several approaches without treating any one slogan as a universal answer.
Learning outcome: Apply three ethical lenses to a concrete choice, recognise their limits, and justify an action without reducing people to numbers or intentions.

Knowledge, belief and evidence
You can believe a bus leaves at nine, correctly guess that it leaves at nine, or know its departure time from a reliable current timetable. The answer may look identical while the route to it differs. This lesson builds on the distinction between claims, reasons and valid inference.
Learning outcome: Distinguish truth, belief and justification; compare perception, inference and testimony; and explain why appropriate confidence may change with new evidence.
