A magnificent, guided tour through Western Philosophy. Starting with Socrates, this tour goes through Parmenides, Heraclitus, Plato, Epictetus, Empericus, St Augustine, St Anselm, Thomas Aquinas, William of Occam, Descartes, Spinoza, Leibniz, Pascal, Locke, Hume, Kant, Hegel, Schopenhauer, Kierkegaard, Nietzsche, Bergson and Husserl. Each philosopher's core thought is described in just a few pages. I personally, for the first time, got the essence of most of the 23 philosophers except Spinoza, Kant, Bergson and Husserl. A third / fourth reading might help which I shall do later. Not bad given the density with which knowledge has been packed in just 200 pages. Thoroughly enjoyed it.
