Episode 087 - Earthquakes and The Water Cycle

Welcome to Episode Eighty-Seven of Lucretius Today. I am your host Cassius, and together with my panelists from the EpicureanFriends.com forum, we'll walk you through the six books of Lucretius' poem, and 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. For anyone who is not familiar with our podcast, please visit EpicureanFriends.com where you will find our goals and our ground rules. If you have any questions about those, please be sure to contact us at the forum for more information. In this Episode 87 we will read approximately Latin lines 527 - 700 as we discuss earthquakes and the water cycle explanation as to why the seas never fill up over time, as we continue further into Book Six. Now let's join Martin reading today's text.Browne 1743[535] Learn now the cause of earthquakes: And first, you are to suppose that the Earth is the same below as it is above, that it is every way full of winds and caverns, and that it holds within its bowels many lakes, and pools, and rocks, and broken stones. You must believe that many hidden rivers flow with rapid waves within, and roll the jagged rocks along their tide, for the laws of nature require that the Earth within and without should be the same.[543] This being premised and supposed: the Earth trembles and shakes above with dreadful ruin, when age has tumbled in these mighty caverns; for then whole mountains sink, and in a moment, with the horrid shock, spread frightful tremblings all abroad. And no wonder, since whole houses by the highway-side will quake as carts, with no great weight, pass through the streets, and so they start as chariots swiftly drive with mettled horses, they shake at every jumping of the wheel.[552] This happens likewise when great weights of earth, loosened by time, plunge down into these deep and mighty lakes, for then the waters rage, and the earth reels and staggers with the shock; as a vessel on the ground cannot stand firm unless the liquor ceases to ferment and toss within.[557] Besides, when winds, collected in the caverns of the earth, direct their force one way, and beat with fury on these hollow places, the earth inclines that way where the winds point their stroke; and our buildings raised above, nod that way too. The highest shake the most; the hanging beams start from the wall, and threaten to fly out. And yet men are afraid to think that Nature has fixed a fatal time when this great world shall be destroyed, and fall to ruin, although they see the heavy mass of earth leaning and tumbling to pieces. And did not the winds take time to breathe, nothing could check their fury, or keep them from destroying everything before them. But since they cease by turns, then rage again, and storm with double force, and are again repelled, hence it is that the earth oftener threatens us with ruin than actually effects it. It inclines only, and then falls back, and though moved aside, settles with all its weight again in its former place. For this reason all our houses tremble and reel; the highest shakes the most, the middle less, the lowest little or nothing.[577] The great tremblings of the earth may arise yet from another cause, when wind or violent blasts (raised either from without or within the earth itself) throw themselves furiously into these hollow caverns, and in these vast dens roar and toss themselves about, and when they have rolled within, and raged with all their might, they break abroad at last, and cleave the solid Earth, and make a hideous chasm. This happened at Sidon, a city of the Tyrians, and at Aegae in Peloponnesus. What cities has this eruption of the wind destroyed? What earthquakes has it produced? At land, the walls of many towns have tumbled...
