Welcome to Episode Fifty-Eight 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 check back to Episode One for a discussion of our goals and our ground rules. If you have any question about that, please be sure to contact us at Epicureanfriends.com for more information.

Podcast 58 - The Mind's Direct Receipt of Images

Latin Lines 722 - 822

Browne 1743

And now attend, and observe in short, what things affect the mind, and from whence proceed those objects that make an impression upon it. First then, I say that subtle images of things, a numerous train of them, wander about in every way and in various manners. These, as they meet, easily twine and are joined together in the air, as threads of gold or the web of a spider; for these are much finer in their contexture than those images that strike the eye and move the sight. These pierce through the pores of the body and move the subtle nature of the mind within, and affect the sense. Hence it is that we see Centaurs, and the limbs of Scylla's, and the heads of Cerberus, and the shadows of those who have long since been dead, and whose bones are rotting in the grave; because images of all kinds are ever wandering about; some of their own accord are formed in the air, some are continually flying off from various bodies, and others rise from these images mixed together. For it is certain that the image of a Centaur never flowed from one that was alive; for there was never such an animal in nature, but when the image of a horse met by chance with the image of a man, it immediately stuck to it, which it easily does, by reason of the subtlety of its nature and the fineness of its texture; and all other monstrous figures are formed after the same manner. These images being exceeding light, and easily put in motion (as I observed before) each of them affects the mind at one stroke; for the mind is of a very subtle nature, and wonderfully disposed to move.

That the mind is moved, as I observed, by the images of things, you may easily collect from hence, that what we perceive by the mind is exactly like what we see with our eyes, and therefore they must of necessity be both affected by the same things, and in the same manner. And so, when I said, for instance, that I see a lion by means of the image that strikes upon the eyes, I know by the same rule that the mind is moved by another image of a lion, which it equally and no less sees, than the eye sees the image proper to it; with this difference only, that the mind can perceive images of a more thin and subtle nature.

Nor from any other reason is the mind awake when the body is asleep, but because those very images affect the mind which were used to move the sense when we were awake, so that we fully believe we see a person who has been long since dead and buried in the grave; and it cannot well be otherwise, because all the senses of the body are obstructed and bound up by sleep, and therefore have no power to convince us of the contrary. Besides, the memory is feeble and languishes by rest, and makes no objection to satisfy us, that the man has been long in the arms of death, whom the mind really believes it sees alive.

And then it is no wonder that the images seem to move, and to throw their arms and the rest of their limbs to exact time, and thus they seem to do when we are in a dream, for when the first image is gone, and another springs up in a different posture, the first, we think, has changed its shape; and all this, you must conceive, is done in an instant of time. There are many other inquiries about things of this nature and we must enter into long disputes if we attempt to give a distinct answer to every one.

First then, it is asked, How is it that whatever we desire to think of the mind immediately thinks upon that very thing? Is it that the images are always ready at the command of the will? Does the image immediately occur to us the moment we desire? If we fancy to think of the sea, the earth, the heavens, of senates, shows, feasts, battles, does nature form these and provide them ready at our nod? Especially since the minds of others, that are in the same country and in the same place with us, think things quite different from these? And then, since we see images in our sleep to step to time, to move their pliant limbs, and throw about their tender arms alternately, and keep due measure with their feet, are they taught this by Art? Have they learnt to dance, that thus they play their wanton sports by night? Is not this the truth rather, that what we take for one moment of time, this present Now, has many parts included, as we find by reason? And therefore it is that in every instant there are a thousand different images always ready in every place, so numerous are they, and so apt to move; and then they are so exceeding subtle, that the mind cannot possibly perceive them distinctly, without the nicest diligence. And so those images die away unobserved, which the mind does not apply itself to receive, but it does apply itself closely to distinguish the image it hopes to find, and therefore sees it.

Don't you observe that the eyes, when they would discover an object exceeding small, contract themselves close and provide for it, nor can they accurately distinguish, except they do so? And you will find, even in things ever so plain, unless you strictly apply your mind, they will be as if they were utterly obscure, and at the greatest distance undiscovered. Where is the wonder then that the mind should lose the observation of all other images but those it particularly inquires after and is employed about? Besides, we often mistake small objects for great, and so we contribute to our own delusion and impose upon ourselves. It happens likewise that sometimes an image of a different kind presents itself to the mind. Thus the form that was before a woman now shows itself a man, or some other person of a different age and complexion, but this we are not to wonder at, since the senses are all asleep, and we are wholly in a state of forgetfulness.
