POLUS: O Chaerephon, there are many arts among mankind which are experimental, and have their origin in experience, for experience makes the days of men to proceed according to art, and inexperience according to chance, and different persons in different ways are proficient in different arts, and the best persons in the best arts.
Po. Kerefon, gizakien artean arte asko dira esperientzien bidez aurkitutakoak, eskarmentuak eragiten baitu gure bizitza artez pasatzea, eskarmentu ezak ordea ausaz pasatzea.
