De Natura Deorum

De Natura Deorum (On the Nature of the Gods) is a philosophical dialogue by Roman orator Cicero written in 45 BC. It is laid out in three "books", each of which discuss the theology of different Roman and Greek philosophers. The dialogue uses a discussion of Stoic, Epicurean, and skeptical theories to examine fundamental questions of theology.

Description

The dialogue is on the whole narrated by Cicero himself, though he does not play an active part in the discussion. Gaius Velleius represents the Epicurean school, Quintius Lucilius Balbus argues for the Stoics, and Gaius Cotta speaks for Cicero's own Academic skepticism. The first book of the dialogue contains Cicero's introduction, Velleius' case for the Epicurean theology and Cotta's criticism of Epicureanism. Book II focuses on Balbus' explanation and defense of Stoic theology. Book III lays out Cotta's criticism of Balbus' claims.

This work, alongside De Officiis and De Divinatione was highly influential on the philosophes of the 18th century; Voltaire called it "(...) perhaps the best book of all antiquity".^[1]

Quotes

• The consequence of which is that there are many things probable; and although they are not subjects of actual perception to our senses, yet they have so grand and glorious an aspect that a wise man governs his life thereby. (To us, probability is the very guide of life) [Lat., Res enim nulla est, de qua tantopere non solum indocti, sed etiam docti dissentiant; quorum opiniones cum tam variae sint tamque inter se dissidentes, alterum fieri profecto potest, ut earum nulla, alterum certe non potest, ut plus una vera sit.(I, 5)
• We, on the contrary, make blessedness of life depend upon an untroubled mind, and exemption from all duties. (We think a happy life consists in tranquility of mind). [Lat., Nos autem beatam vitam in animi securitate et in omnium vacatione munerum ponimus.] (I, 53)
• Because all the sick do not recover, therefore medicine is not an art. [Lat., Ne aegri quidem quia non omnes convalescunt, idcirco ars nulla medicina est.] (II, 12)
• Things perfected by nature are better than those finished by art. [Lat., Meliora sunt ea quae natura quam illa quae arte perfecta sunt.] (II, 87)
• There never was a great man unless through divine inspiration.^[2] [Lat., Nemo igitur vir magnus sine aliquo adflatu divino umquam fuit.] (II, 167)
