Episode 348 - EATAQ30 - Neither Logic Nor Logos Are Shortcuts To Truth

Welcome to Episode 348 of Lucretius Today. This is a podcast dedicated to the poet Lucretius, who wrote "On The Nature of Things," the most complete presentation of Epicurean philosophy left to us from the ancient world. Each week we walk you through the Epicurean texts, and we discuss how Epicurean philosophy can apply to you today. If you find the Epicurean worldview attractive, we invite you to join us in the study of Epicurus at EpicureanFriends.com, where we discuss this and all of our podcast episodes.

This week we are continuing our series reviewing Cicero's "Academic Questions" from an Epicurean perspective, which gives us an overview of the issues that split Plato's Academy and helps us understand Epicurus' position on the same issues. This week will continue in Section 14 of Book Two.

Our text will come from
Cicero - Academic Questions - Yonge We'll likely stick with Yonge primarily, but we'll also refer to the Rackham translation here: Cicero On Nature Of Gods Academica Loeb Rackham : Free Download, Borrow, and Streaming : Internet Archive

In the meantime I want to note a connection between a section of the letter to Herodotus that Joshua quotes in this episode and the issue of knowledge which is the overall topic of what Cicero is discussing.

At around the 20 minute mark we bring out the issue of necessity as it relates to physics and the swerve. The connection that we need to make more clear as we go further is that in the issue of knowledge "necessity" has important implications for truth. The discussion of "Methods of Inference" we will see in Philodemus relates to the question of "Signs" and whether there are infallible "signs" to indicate that something is true. It seems to me that there's no way that you can have an "infallible sign" unless you also have a doctrine in which in some cases some things are "necessary." You can't say that a sign can be relied on with absolute confidence unless you are also confident that there is a necessary connection between the sign and what it indicates.

So when Epicurus says that some things occur by chance, some by necessity, and some by our own action, and when he cites in the letter to Herodotus that the motions of the stars result from the necessity of how they were set in motion from the foundation of the world, Epicurus is agreeing that some things are in fact necessary. The reason this came up briefly today is that this conclusion is not overruled by the existence of the swerve, and so once again I cited A. A. Long's "Chance and Natural Law in Epicureanism" which brings out this point.
