The nature of the Gods ; and On divination

The eminent Roman statesman and philosopher Marcus Tullius Cicero (106-43 b.c.e.) analyses the positions of the Stoic, Epicurean, and Academic schools on the existence and nature of the gods, and whether they act in the interests of humankind. Cotta, the Academic spokesman, criticises his Epicurean and Stoic interlocutors for their failures, respectively, to account for human freedom and for the accidents and evils that occur in life. Lacking sure knowledge of what gods are, human beings are left to their own intelligence and natural abilities to make their way in an uncertain world. In the dialogue of 'On Divination', Cicero and his brother, Quintus, examine various sorts of divination on Stoic principles, which Quintus upholds. Cicero counters that there is no such science of divination, and that the ambiguities and absurdities inherent in oracles, prodigies, and dreams preclude any divine agency. They are, rather, the result of natural phenomena or coincidence.
