TEXT 30: Cicero On the Nature of the Gods 2.3-164 (selections)

Our school exhaustively divides this whole question about the immortal gods into four parts: first they teach that there are gods, then what they are like, then that the cosmos is governed by them, and finally that they take thought for the affairs of human beings."
