Episode 090 - Special Guest Panelist - Preparation for Discussion of Magnetism

Welcome to Episode Ninety 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 90 we will read approximately Latin lines 906-998 as we prepare to discuss magnetism.Today we have with us a guest panelist, Joshua, who is a regular member of the EpicureanFriends.com forum. Now let's join Joshua reading today's text.Browne 1743[906] And now I shall begin to show by what power of nature it is that the stone (which the Greeks call a magnet, from the country that produces it, for it is found in the region of the Magnetes) has the virtue to attract iron. Men are amazed at the qualities of this stone, for it will make a chain of several little rings of iron, without a link between, to hang together entirely from itself. You may sometimes see five or more hanging straight down, and play in the gentle air, as they stick close and depend at the bottom one upon another; the ring that follows feels the attraction and power of the stone from that above it. So strongly is the virtue of the magnet communicated to the several rings; it acts with so great a force.[917] In inquiries of this nature many things are to be first proved before we can fix upon the true cause; we must trace the subject through many long and intricate difficulties; and therefore I beg you will hear me with a willing mind, and with the closest attention.[921] And first, certain seeds must necessarily flow, be sent out, and continually dispersed abroad, from all things whatever we see, which must strike upon the eye and affect the sight. From some bodies a train of smells are always flying off. So cold is emitted from the rivers; heat from the sun; a salt vapor from the water of the sea that eats through walls along the shore, and various sounds are always flying through the air. And as we walk upon the strand, a briny taste frequently offends our mouth, and when we see a bunch of wormwood bruised, the bitterness strikes upon the palate. So plain it is that something is continually flowing off from all bodies, and is scattered about. There is no intermission, the seeds never cease to flow, because the sense is continually affected, we still continue to feel, to see, to smell and hear.[936] Now I shall repeat what I have proved at large in the first book of this poem, that no bodies are perfectly solid, for though it is proper to know this upon many accounts, yet it is of principal use in the subject I now offer to explain. In this place it is necessary to establish this truth, that there is nothing in Nature but body mixed with void. And first, in the deep caverns of the earth, the rocks above will sweat with moisture, and weep with flowing drops; and sweat will flow from all our bodies and through every pore. The beard will grow, and hairs spread over our members and our limbs. Nature divides our food through all the veins; it feeds and nourishes the extreme parts, our very nails. We find that cold and heat will pass through brass, will make their way through gold and silver. We know, by feeling the outside of a cup, whether the juice within be hot or cold. And lastly, sounds will pierce stone walls of houses, and so will smells, and cold, and heat. The force of fire, thrown from without, will pass through iron, and scorch the soldiers limbs, though armed about with...
