“Philosophy cannot be taught; it is the application of the sciences to truth.”

“Il y a les sachants et les savants: c'est la mémoire qui fait les uns, c'est la philosophie qui fait les autres. La philosophie ne s'apprend pas; la philosophie est la réunion des sciences acquises au génie qui les applique.”

“My son, philosophy as I understand it, is reducible to no rules by which it can be learned; it is the amalgamation of all the sciences, the golden cloud which bears the soul to heaven.”

“To learn is not to know; there are the learners and the learned. Memory makes the one, philosophy the others.”

“Learning does not make one learned: there are those who have knowledge and those who have understanding. The first requires memory and the second philosophy.”

“...apprendre n'est pas savoir; il y a les sachants et les savants: c'est la memoire qui fait les uns, c'est la philosophie qui fait les autres.”

“Pure love and suspicion cannot dwell together: at the door where the latter enters, the former makes its exit.”
