From a review of The Oxford Handbook of Contemporary Philosophy in The Economist:
Close behind the news headlines lurk abstract puzzles. Freedom and democracy are offered up as justifications for war, yet they themselves are rarely explained or justified. People argue passionately about abortion, uncertain where law and morals meet or what anchors moral convictions. A judge in Dover, Pennsylvania, faced by Christian zealots claiming that evolution is “just a theory”, asks experts to explain what makes theories scientific.
Puzzles are all very well. But arguments have to end. When arguments themselves turn on contentious principles—majority rule, moral truth, science against faith—philosophy will not go away. Shut the door, and back it comes through the window. Philosophy, once readmitted, then turns a characteristic trick. It makes you think how you should be arguing about those principles and tries to make plain what should count as good and bad reasons. It guarantees no answers but does offer the wherewithal to recognise genuine answers when they appear.
