"That man is intellectually of the mass who, in the face of any problem, is satisfied with thinking the first thing he finds in his head. On the contrary, the excellent man is he who condemns what he finds in his mind without previous effort, and only accepts as worthy of him what is still far above him and what requires a further effort in order to be reached."
