Start with Nietzsche. His point is that modern ‘philosophy’ is pretentious scholarship and not, as it was in Greece, a way of life. Nietzsche’s framework is great. Beyond Good and Evil may be called as ‘Beyond Christianity’ - Nietzsche returns to pre-christian ethics & wonders how these might be reconstituted for us today. Most book on philosophy are morbidly dull - Nietzsche's books are perplexing, eye opening, cantakerous, radical and infuriating.
