On the Nature of Things

Titus Lucretius Carus

But those which are the primal germs of things Have power to work more combinations still, Whence divers things can be produced in turn. Now let us also take for scrutiny The homeomeria of Anaxagoras, So called by Greeks, for which our pauper-speech Yieldeth no name in the Italian tongue, Although the thing itself is not o'erhard For explanation. First, then, when he speaks Of this homeomeria of things, he thinks Bones to be sprung from littlest bones minute, And from minute and littlest flesh all flesh, And blood created out of drops of blood, Conceiving gold compact of grains of gold, And earth concreted out of bits of earth, Fire made of fires, and water out of waters, Feigning the like with all the rest of stuff. Yet he concedes not any void in things, Nor any limit to cutting bodies down. Wherefore to me he seems on both accounts To err no less than those we named before. Add too: these germs he feigns are far too frail-- If they be germs primordial furnished forth With but same nature as the things themselves, And travail and perish equally with those, And no rein curbs them from annihilation. For which will last against the grip and crush Under the teeth of death? the fire? the moist? Or else the air? which then? the blood? the bones? No one, methinks, when every thing will be At bottom as mortal as whate'er we mark To perish by force before our gazing eyes. But my appeal is to the proofs above That things cannot fall back to naught, nor yet From naught increase. And now again, since food Augments and nourishes the human frame, 'Tis thine to know our veins and blood and bones And thews are formed of particles unlike To them in kind; or if they say all foods Are of mixed substance having in themselves Small bodies of thews, and bones, and also veins And particles of blood, then every food, Solid or liquid, must itself be thought As made and mixed of things unlike in kind-- Of bones, of thews, of ichor and of blood. Again, if all the bodies which upgrow From earth, are first within the earth, then earth Must be compound of alien substances. Which spring and bloom abroad from out the earth. Transfer the argument, and thou may'st use The selfsame words: if flame and smoke and ash Still lurk unseen within the wood, the wood Must be compound of alien substances Which spring from out the wood. Right here remains A certain slender means to skulk from truth, Which Anaxagoras takes unto himself, Who holds that all things lurk commixed with all While that one only comes to view, of which The bodies exceed in number all the rest, And lie more close to hand and at the fore-- A notion banished from true reason far. For then 'twere meet that kernels of the grains Should oft, when crunched between the might of stones, Give forth a sign of blood, or of aught else Which in our human frame is fed; and that Rock rubbed on rock should yield a gory ooze. Likewise the herbs ought oft to give forth drops Of sweet milk, flavoured like the uddered sheep's; Indeed we ought to find, when crumbling up The earthy clods, there herbs, and grains, and leaves, All sorts dispersed minutely in the soil; Lastly we ought to find in cloven wood Ashes and smoke and bits of fire there hid. But since fact teaches this is not the case, 'Tis thine to know things are not mixed with things Thuswise; but seeds, common to many things, Commixed in many ways, must lurk in things. "But often it happens on skiey hills" thou sayest, "That neighbouring tops of lofty trees are rubbed One against other, smote by the blustering south, Till all ablaze with bursting flower of flame." Good sooth--yet fire is not ingraft in wood, But many are the seeds of heat, and when Rubbing together they together flow, They start the conflagrations in the forests. Whereas if flame, already fashioned, lay Stored up within the forests, then the fires Could not for any time be kept unseen, But would be laying all the wildwood waste And burning all the boscage. Now dost see (Even as we said a little space above) How mightily it matters with what others, In what positions these same primal germs Are bound together? And what motions, too, They give and get among themselves? how, hence, The same, if altered 'mongst themselves, can body Both igneous and ligneous objects forth-- Precisely as these words themselves are made By somewhat altering their elements, Although we mark with name indeed distinct The igneous from the ligneous. Once again, If thou suppose whatever thou beholdest, Among all visible objects, cannot be, Unless thou feign bodies of matter endowed With a like nature,--by thy vain device For thee will perish all the germs of things: 'Twill come to pass they'll laugh aloud, like men, Shaken asunder by a spasm of mirth, Or moisten with salty tear-drops cheeks and chins. THE INFINITY OF THE UNIVERSE Now learn of what remains! More keenly hear! And for myself, my mind is not deceived How dark it is: But the large hope of praise Hath strook with pointed thyrsus through my heart; On the same hour hath strook into my breast Sweet love of the Muses, wherewith now instinct, I wander afield, thriving in sturdy thought, Through unpathed haunts of the Pierides, Trodden by step of none before. I joy To come on undefiled fountains there, To drain them deep; I joy to pluck new flowers, To seek for this my head a signal crown From regions where the Muses never yet Have garlanded the temples of a man: First, since I teach concerning mighty things, And go right on to loose from round the mind The tightened coils of dread religion; Next, since, concerning themes so dark, I frame Songs so pellucid, touching all throughout Even with the Muses' charm--which, as 'twould seem, Is not without a reasonable ground: But as physicians, when they seek to give Young boys the nauseous wormwood, first do touch The brim around the cup with the sweet juice And yellow of the honey, in order that The thoughtless age of boyhood be cajoled As far as the lips, and meanwhile swallow down The wormwood's bitter draught, and, though befooled, Be yet not merely duped, but rather thus Grow strong again with recreated health: So now I too (since this my doctrine seems In general somewhat woeful unto those Who've had it not in hand, and since the crowd Starts back from it in horror) have desired To expound our doctrine unto thee in song Soft-speaking and Pierian, and, as 'twere, To touch it with sweet honey of the Muse-- If by such method haply I might hold The mind of thee upon these lines of ours, Till thou see through the nature of all things, And how exists the interwoven frame. But since I've taught that bodies of matter, made Completely solid, hither and thither fly Forevermore unconquered through all time, Now come, and whether to the sum of them There be a limit or be none, for thee Let us unfold; likewise what has been found To be the wide inane, or room, or space Wherein all things soever do go on, Let us examine if it finite be All and entire, or reach unmeasured round And downward an illimitable profound. Thus, then, the All that is is limited In no one region of its onward paths, For then 'tmust have forever its beyond. And a beyond 'tis seen can never be For aught, unless still further on there be A somewhat somewhere that may bound the same-- So that the thing be seen still on to where The nature of sensation of that thing Can follow it no longer. Now because Confess we must there's naught beside the sum, There's no beyond, and so it lacks all end. It matters nothing where thou post thyself, In whatsoever regions of the same; Even any place a man has set him down Still leaves about him the unbounded all Outward in all directions; or, supposing A moment the all of space finite to be, If some one farthest traveller runs forth Unto the extreme coasts and throws ahead A flying spear, is't then thy wish to think It goes, hurled off amain, to where 'twas sent And shoots afar, or that some object there Can thwart and stop it? For the one or other Thou must admit and take. Either of which Shuts off escape for thee, and does compel That thou concede the all spreads everywhere, Owning no confines. Since whether there be Aught that may block and check it so it comes Not where 'twas sent, nor lodges in its goal, Or whether borne along, in either view 'Thas started not from any end. And so I'll follow on, and whereso'er thou set The extreme coasts, I'll query, "what becomes Thereafter of thy spear?" 'Twill come to pass That nowhere can a world's-end be, and that The chance for further flight prolongs forever The flight itself. Besides, were all the space Of the totality and sum shut in With fixed coasts, and bounded everywhere, Then would the abundance of world's matter flow Together by solid weight from everywhere Still downward to the bottom of the world, Nor aught could happen under cope of sky, Nor could there be a sky at all or sun-- Indeed, where matter all one heap would lie, By having settled during infinite time. But in reality, repose is given Unto no bodies 'mongst the elements, Because there is no bottom whereunto They might, as 'twere, together flow, and where They might take up their undisturbed abodes. In endless motion everything goes on Forevermore; out of all regions, even Out of the pit below, from forth the vast, Are hurtled bodies evermore supplied. The nature of room, the space of the abyss Is such that even the flashing thunderbolts Can neither speed upon their courses through, Gliding across eternal tracts of time, Nor, further, bring to pass, as on they run, That they may bate their journeying one whit: Such huge abundance spreads for things around-- Room off to every quarter, without end. Lastly, before our very eyes is seen Thing to bound thing: air hedges hill from hill, And mountain walls hedge air; land ends the sea, And sea in turn all lands; but for the All Truly is nothing which outside may bound. That, too, the sum of things itself may not Have power to fix a measure of its own, Great nature guards, she who compels the void To bound all body, as body all the void, Thus rendering by these alternates the whole An infinite; or else the one or other, Being unbounded by the other, spreads, Even by its single nature, ne'ertheless Immeasurably forth.... Nor sea, nor earth, nor shining vaults of sky, Nor breed of mortals, nor holy limbs of gods Could keep their place least portion of an hour: For, driven apart from out its meetings fit,
