See how Kuest teaches it

It asks before it tells, so you do the thinking and it sticks.

You: Is this argument valid? “All fish can swim. Dolphins can swim. So dolphins are fish.”
Kuest: Before we judge it, what does it mean for an argument to be valid?
You: That the premises are true. Both premises here are true, so it's valid.
Kuest: True premises are part of the story, but validity is about the form: if the premises were true, would the conclusion have to be true? Can you picture both premises true and the conclusion false?
You: Yes, that's the real world. Fish swim and dolphins swim, but dolphins are mammals. So the conclusion doesn't follow, and it's invalid.
Kuest: Exactly. Being able to swim doesn't make something a fish. And a sound argument needs both: a valid form and true premises.

Valid means the conclusion must follow if the premises are true; sound means valid with premises that actually are true.

The method

How to study Philosophy with Kuest

Philosophy is learned by arguing, not by memorizing who said what. Read slowly, restate each argument in your own premises and conclusion, then test it against the strongest objection you can find, out loud and on paper.

  1. Bring the readingSnap a photo

    Snap or paste the passage from Plato, Descartes or Kant you're working on and read it with Kuest paragraph by paragraph.

  2. Reconstruct the argumentTutor chat

    Put the author's argument into numbered premises and a conclusion, and ask Kuest where your version drifts from the text.

  3. Map the positionsTeaching board

    Lay out rival views, like dualism versus physicalism, on the teaching board with the main argument and objection for each.

  4. Defend a view out loudVoice tutor

    Argue a position with the voice tutor and respond to the objections it raises, the way a seminar would push you.

  5. Keep the terms and thinkers straightFlashcards

    Review key terms and who argued what with spaced flashcards, so they're ready for exams and discussion.

  6. Test your understandingQuizzes

    Take quizzes that ask you to spot fallacies, identify argument forms and apply theories to new cases.
