Sloterdijk delves into the work and times of Aristotle, Augustine, Bruno, Descartes, Foucault, Fichte, Hegel, Husserl, Kant, Kierkegaard, Leibniz, Marx, Nietzsche, Pascal, Plato, Sartre, Schelling, Schopenhauer, and Wittgenstein. He provocatively juxtaposes Plato against shamanism and Marx against Gnosticism, revealing both the vital external influences shaping these intellectuals' thought and the excitement and wonder generated by the application of their thinking in the real world. The philosophical "temperament" as conceived by Sloterdijk represents the uniquely creative encounter between the mind and a diverse array of cultures. It marks these philosophers' singular achievements and the special dynamic at play in philosophy as a whole. Creston Davis's introduction details Sloterdijk's own temperament, surveying the celebrated thinker's intellectual context, rhetorical style, and philosophical persona.
