Men commonly think according to their inclinations, speak according to their learning and imbibed opinions; but generally act according to custom. [ Bacon ]

This, therefore, is a law not found in books, but written on the fleshly tablets of the heart, which we have not learned from man, received or read, but which we have caught up from Nature herself, sucked in and imbibed; the knowledge of which we were not taught, but for which we were made; we received it not by education, but by intuition. [ Cicero ]
