When it comes to the life of mind and spirit, people often think they can learn something from philosophers. Richard Wahle, an official representative of modern philosophy, has said something rather strange about philosophy, and not only modern philosophy but also the philosophy of earlier times. He said that earlier philosophers were like people owning restaurants where various chefs and waiters produced and presented unwholesome dishes.
