A recent book of introductory philosophy is Timothy Williamson’s Tetralogue: I’m Right, You’re Wrong. Instead of using a dialogue with two viewpoints used by some classical philosophers, Williamson structures his book into a tetralogue, or a conversation with four viewpoints.
The viewpoints are portrayed by four individuals as they enjoy a lengthy train ride: Zac (Relativism), Sarah (Naturalism, Empiricism, Skepticism, Fallibilism, Materialism, Scientism), Bob (Culturalism, Traditionalism, Conservatism, Ancestralism), and Roxana (Rationalism, Logicalism).
Who’s right and who’s wrong? I haven’t read it yet but it looks interesting!
