Philosophy Thread

Learn to think — really think — by playing. Philosophy Thread is a free, Duolingo-style game that begins with the oldest habit of the human mind — wonder — and climbs from there through the great branches of philosophy, all the way to becoming a thinker in your own right.

The worlds

The Agora (what philosophy is), the Hall of Reason (logic & arguments), the Good Life (ethics), the Search for Truth (knowledge), the Nature of Reality (metaphysics), Know Thyself (the mind), the Just City (justice), Beauty & Art (aesthetics), the Big Questions of Faith, the Wisdom of the East, Thinking About Thinking (method), and the Great Conversation at the summit.

Short, friendly 2–4 minute lessons with instant feedback. Boss battles against friendly Guardians. Hearts, streaks, levels and badges.

Every contested question — in ethics, politics, and faith — is presented fairly, so learners think for themselves. Works offline and installs to your home screen. No account needed.
