A modern biography of Ludwig Wittgenstein, Monk traces Wittgenstein’s philosophy through his extremes: asceticism, wealth renounced, war service, teaching, solitude, and the relentless ethical demand he placed on himself and others.

His writing process was much like Wittgenstein's philosophical practice — exacting, punishing, yet lived. Monk resists mythologising while still taking Wittgenstein’s severity seriously, showing how the Tractatus and the later philosophy emerge from a continuous struggle over clarity, responsibility, and self-deception.

It’s essential for readers interested in philosophy as character, not just argument.
