"The best student in physics or mathematics, at school or university, is not one who memorizes formulae but one who is aware of the reason for them. For students, the more simply and docilely they receive the contents with which their teachers "fill" them in the name of knowledge, the less they are able to think and the more they become merely repetitive. The best philosophy student is not one who discourses, "ipsis verbis," on the philosophy of Plato, Marx, or Kant but one who thinks critically about their ideas and takes the risk of thinking too."
