Lucretius Today is a podcast dedicated to learning Epicurean philosophy through study of the poet Lucretius, who lived in the age of Julius Caesar and wrote "On The Nature of Things," the only complete presentation of Epicurus' ideas left to us from the ancient world. We'll walk you line by line through the six books of Lucretius' poem, and we'll discuss how Epicurean philosophy can apply to you today. In this podcast we won't be talking about modern political issues. How you apply Epicurus in your own life is entirely up to you. Over at the Epicureanfriends.com web forum, we apply this approach by following a set of ground rules we call "Not Neo-Epicurean, But Epicurean." Epicurean philosophy is not a religion, it''s not Stoicism, it's not Humanism, it's not Libertarianism, it's not Atheism, and it's not Marxism or any other philosophy - it is unique in the history of Western Civilization, and as we explore Lucretius's poem you'll quickly see how that is the case.

Episode 129 - Letter to Pythocles 03 - The Implications Of the Epicurean Position On The Size of the Sun
Welcome to Episode One Hundred Twenty Nine of Lucretius Today. This is a podcast dedicated to the poet Lucretius, who wrote "On The Nature of Things," the only complete presentation of Epicurean philosophy left to us from the ancient world. I am your host Cassius, and together with our panelists from the EpicureanFriends.com forum, we'll walk you through the ancient Epicurean texts, and we'll discuss how Epicurean philosophy can apply to you today. We encourage you to study Epicurus for yourself, and we suggest the best place to start is the book "Epicurus and His Philosophy" by Canadian professor Norman DeWitt. If you find the Epicurean worldview attractive, we invite you to join us in the study of Epicurus at EpicureanFriends.com, where you will find a discussion thread for each of our podcast episodes and many other topics. Today we continue Epicurus' Letter to Pythocles and we look at the implications of the Epicurean position on the size of the sun. Now let's join Joshua reading today's text:
BAILEY:
[91] The size of sun (and moon) and the other stars is for us what it appears to be; and in reality it is either (slightly) greater than what we see or slightly less or the same size: for so too fires on earth when looked at from a distance seem to the senses. And every objection at this point will easily be dissipated, if we pay attention to the clear vision, as I show in my books about nature.
[92] The risings and settings of the sun, moon, and other heavenly bodies may be due to kindling and extinction, the composition of the surrounding matter at the places of rising and setting being such as to lead to these results: for nothing in phenomena is against it. Or again, the effect in question might be produced by their appearance over the top of the earth, and again the interposition of the earth in front of them: for once more nothing in phenomena is against it.
Their motions may not impossibly be due to the revolution of the whole heaven, or else it may remain stationary, and they may revolve owing to the natural impulse towards the east, which was produced at the beginning of the world . . . . . by an excessive heat owing to a spreading of the fire which is always moving on to the regions nearest in succession.
[93] The tropics of sun and moon may be caused owing to an obliquity of the whole heaven, which is constrained into this position in the successive seasons; or equally well by an outward impulsion of a current of air, or because the appropriate material successively catches fire, as the former fails; or again, from the beginning this particular form of revolution may have been assigned to these stars, so that they move in a kind of spiral. For all these and kindred explanations are not at variance with any clear-seen facts, if one always clings in such departments of inquiry to the possible and can refer each point to what is in agreement with phenomena without fearing the slavish artifices of the astronomers.
