Work with concepts such as justice, knowledge, freedom, personhood, and beauty as tools for thinking. Break a concept into features, test what seems central, and notice where people may use the same word differently.

Recognize when a word or sentence has more than one possible meaning, or when its boundaries are unclear. Practice separating ambiguity from vagueness so a philosophical question becomes easier to answer.

Draw distinctions that prevent ideas from being lumped together too quickly, such as legal versus moral, explaining versus justifying, or causing versus being responsible. Use distinctions to make a messy issue more precise.

Use concrete examples to clarify what a claim or concept is supposed to include. Practice choosing examples that reveal the point of a question instead of distracting from it.

Use counterexamples to test a definition or general claim. Practice finding a case that appears to meet the stated conditions but still makes the claim look false or incomplete.

Work with imagined cases that isolate one feature of a problem, such as a machine that creates perfect experiences or a person who changes memories. Trace how thought experiments test intuitions about concepts and principles.

Refine broad claims by adding limits, exceptions, or scope markers such as all, some, only if, usually, and unless. Practice making a claim strong enough to say something meaningful without making it too easy to refute.

Notice the background assumptions built into how a question is asked, such as what counts as success, harm, choice, or evidence. Practice reframing a philosophical problem when the original wording quietly favors one answer.
