- But when ypu talk about the political system which is worthy of philosophy, which of the present-day systems do you mean?
-- None of them, I replied. That's precisely my complaint. There is no present-day political regime which lives up to the philosopher's nature. That's why his nature is twisted and transformed. It's like the seed of some exotic plant. When it's sown outside its native land, it tends to lose its distinguishing properties and vigour, and degenerate into the indigenous variety
