I want to know the answer to the following question:
What is the characteristic that most separates humans from animals?
All the background I'm provided with is that "Gellius maintains that this common usage is wrong, and that model writers of Latin, such as Cicero and others, used the word only to mean what we might call "humane" or "polite" learning, or the Greek equivalent Paideia.". Is that enough to answer the question?
