Need philosophy on the run? Try Glyn Hughes' Squashed Philosophers. Hits the "highlights" leaves out the heavy lifting.
Does miss some profound thinking of our time, as there is no mention of deep thoughts such as the Murphy Principle of Duality: "Tracers work both ways" or Murphy's Synchronicity Theorems: "Field experience is something you don't get until just after you need it" and "The enemy invariably attacks on two occasions:
(1) when you're ready for them.
(2) when you're not ready for them." See Collected Works of Murphy.
