If you doubt whether we learn arts, be convinced that we teach them. For partridges teach their young ones to hide themselves by lying upon their backs just before a clod of earth, to escape the pursuit of the fowlers. And you shall observe the old storks, when their young ones first begin to take wing, what care they take to instruct them upon the tops of houses. Nightingales also teach their young ones to sing; insomuch that nightingales taken young out of the nest, and bred up by hand in cages, sing worse, as being deprived of their instructors before their time. So that after I had been a while transformed into this shape, I admired at myself, that I was so easily persuaded by idle arguments of the sophisters to believe that all other creatures were void of sense and reason except man.
