On the Nature of Things · 2 of 30

Book I, Part 2

And now, since I have taught that things cannot Be born from nothing, nor the same, when born, To nothing be recalled, doubt not my words, Because our eyes no primal germs perceive; For mark those bodies which, though known to be In this our world, are yet invisible: The winds infuriate lash our face and frame, Unseen, and swamp huge ships and rend the clouds, Or, eddying wildly down, bestrew the plains With mighty trees, or scour the mountain tops With forest-crackling blasts. Thus on they rave With uproar shrill and ominous moan. The winds, 'Tis clear, are sightless bodies sweeping through The sea, the lands, the clouds along the sky, Vexing and whirling and seizing all amain; And forth they flow and pile destruction round, Even as the water's soft and supple bulk Becoming a river of abounding floods, Which a wide downpour from the lofty hills Swells with big showers, dashes headlong down Fragments of woodland and whole branching trees; Nor can the solid bridges bide the shock As on the waters whelm: the turbulent stream, Strong with a hundred rains, beats round the piers, Crashes with havoc, and rolls beneath its waves Down-toppled masonry and ponderous stone, Hurling away whatever would oppose. Even so must move the blasts of all the winds, Which, when they spread, like to a mighty flood, Hither or thither, drive things on before And hurl to ground with still renewed assault, Or sometimes in their circling vortex seize And bear in cones of whirlwind down the world: The winds are sightless bodies and naught else- Since both in works and ways they rival well The mighty rivers, the visible in form. Then too we know the varied smells of things Yet never to our nostrils see them come; With eyes we view not burning heats, nor cold, Nor are we wont men's voices to behold. Yet these must be corporeal at the base, Since thus they smite the senses: naught there is Save body, having property of touch. And raiment, hung by surf-beat shore, grows moist, The same, spread out before the sun, will dry; Yet no one saw how sank the moisture in, Nor how by heat off-driven. Thus we know, That moisture is dispersed about in bits Too small for eyes to see. Another case: A ring upon the finger thins away Along the under side, with years and suns; The drippings from the eaves will scoop the stone; The hooked ploughshare, though of iron, wastes Amid the fields insidiously. We view The rock-paved highways worn by many feet; And at the gates the brazen statues show Their right hands leaner from the frequent touch Of wayfarers innumerable who greet. We see how wearing-down hath minished these, But just what motes depart at any time, The envious nature of vision bars our sight. Lastly whatever days and nature add Little by little, constraining things to grow In due proportion, no gaze however keen Of these our eyes hath watched and known. No more Can we observe what's lost at any time, When things wax old with eld and foul decay, Or when salt seas eat under beetling crags. Thus Nature ever by unseen bodies works. THE VOID But yet creation's neither crammed nor blocked About by body: there's in things a void- Which to have known will serve thee many a turn, Nor will not leave thee wandering in doubt, Forever searching in the sum of all, And losing faith in these pronouncements mine. There's place intangible, a void and room. For were it not, things could in nowise move; Since body's property to block and check Would work on all and at an times the same. Thus naught could evermore push forth and go, Since naught elsewhere would yield a starting place. But now through oceans, lands, and heights of heaven By divers causes and in divers modes, Before our eyes we mark how much may move, Which, finding not a void, would fail deprived Of stir and motion; nay, would then have been Nowise begot at all, since matter, then, Had staid at rest, its parts together crammed. Then too, however solid objects seem, They yet are formed of matter mixed with void: In rocks and caves the watery moisture seeps, And beady drops stand out like plenteous tears; And food finds way through every frame that lives; The trees increase and yield the season's fruit Because their food throughout the whole is poured, Even from the deepest roots, through trunks and boughs; And voices pass the solid walls and fly Reverberant through shut doorways of a house; And stiffening frost seeps inward to our bones. Which but for voids for bodies to go through 'Tis clear could happen in nowise at all. Again, why see we among objects some Of heavier weight, but of no bulkier size: Indeed, if in a ball of wool there be As much of body as in lump of lead, The two should weigh alike, since body tends To load things downward, while the void abides, By contrary nature, the imponderable. Therefore, an object just as large but lighter Declares infallibly its more of void; Even as the heavier more of matter shows, And how much less of vacant room inside. That which we're seeking with sagacious quest Exists, infallibly, commixed with things- The void, the invisible inane. Right here I am compelled a question to expound, Forestalling something certain folk suppose, Lest it avail to lead thee off from truth: Waters (they say) before the shining breed Of the swift scaly creatures somehow give, And straightway open sudden liquid paths, Because the fishes leave behind them room To which at once the yielding billows stream. Thus things among themselves can yet be moved, And change their place, however full the Sum- Received opinion, wholly false forsooth. For where can scaly creatures forward dart, Save where the waters give them room? Again, Where can the billows yield a way, so long As ever the fish are powerless to go? Thus either all bodies of motion are deprived, Or things contain admixture of a void Where each thing gets its start in moving on. Lastly, where after impact two broad bodies Suddenly spring apart, the air must crowd The whole new void between those bodies formed; But air, however it stream with hastening gusts, Can yet not fill the gap at once- for first It makes for one place, ere diffused through all. And then, if haply any think this comes, When bodies spring apart, because the air Somehow condenses, wander they from truth: For then a void is formed, where none before; And, too, a void is filled which was before. Nor can air be condensed in such a wise; Nor, granting it could, without a void, I hold, It still could not contract upon itself And draw its parts together into one. Wherefore, despite demur and counter-speech, Confess thou must there is a void in things.

And still I might by many an argument Here scrape together credence for my words. But for the keen eye these mere footprints serve, Whereby thou mayest know the rest thyself. As dogs full oft with noses on the ground, Find out the silent lairs, though hid in brush, Of beasts, the mountain-rangers, when but once They scent the certain footsteps of the way, Thus thou thyself in themes like these alone Can hunt from thought to thought, and keenly wind Along even onward to the secret places And drag out truth. But, if thou loiter loth Or veer, however little, from the point, This I can promise, Memmius, for a fact: Such copious drafts my singing tongue shall pour From the large well-springs of my plenished breast That much I dread slow age will steal and coil Along our members, and unloose the gates Of life within us, ere for thee my verse Hath put within thine ears the stores of proofs At hand for one soever question broached. NOTHING EXISTS per se EXCEPT ATOMS AND THE VOID But, now again to weave the tale begun, All nature, then, as self-sustained, consists Of twain of things: of bodies and of void In which they're set, and where they're moved around. For common instinct of our race declares That body of itself exists: unless This primal faith, deep-founded, fail us not, Naught will there be whereunto to appeal On things occult when seeking aught to prove By reasonings of mind. Again, without That place and room, which we do call the inane, Nowhere could bodies then be set, nor go Hither or thither at all- as shown before. Besides, there's naught of which thou canst declare It lives disjoined from body, shut from void- A kind of third in nature. For whatever Exists must be a somewhat; and the same, If tangible, however fight and slight, Will yet increase the count of body's sum, With its own augmentation big or small; But, if intangible and powerless ever To keep a thing from passing through itself On any side, 'twill be naught else but that Which we do call the empty, the inane. Again, whate'er exists, as of itself, Must either act or suffer action on it. Or else be that wherein things move and be: Naught, saving body, acts, is acted on; Naught but the inane can furnish room. And thus, Beside the inane and bodies, is no third Nature amid the number of all things- Remainder none to fall at any time Under our senses, nor be seized and seen By any man through reasonings of mind. Name o'er creation with what names thou wilt, Thou'lt find but properties of those first twain, Or see but accidents those twain produce.

A property is that which not at all Can be disjoined and severed from a thing Without a fatal dissolution: such, Weight to the rocks, heat to the fire, and flow To the wide waters, touch to corporal things, Intangibility to the viewless void. But state of slavery, pauperhood, and wealth, Freedom, and war, and concord, and all else Which come and go whilst Nature stands the same, We're wont, and rightly, to call accidents. Even time exists not of itself; but sense Reads out of things what happened long ago, What presses now, and what shall follow after: No man, we must admit, feels time itself, Disjoined from motion and repose of things. Thus, when they say there "is" the ravishment Of Princess Helen, "is" the siege and sack Of Trojan Town, look out, they force us not To admit these acts existent by themselves, Merely because those races of mankind (Of whom these acts were accidents) long since Irrevocable age has borne away: For all past actions may be said to be But accidents, in one way, of mankind,- In other, of some region of the world. Add, too, had been no matter, and no room Wherein all things go on, the fire of love Upblown by that fair form, the glowing coal Under the Phrygian Alexander's breast, Had ne'er enkindled that renowned strife Of savage war, nor had the wooden horse Involved in flames old Pergama, by a birth At midnight of a brood of the Hellenes. And thus thou canst remark that every act At bottom exists not of itself, nor is As body is, nor has like name with void; But rather of sort more fitly to be called An accident of body, and of place Wherein all things go on. CHARACTER OF THE ATOMS Bodies, again, Are partly primal germs of things, and partly Unions deriving from the primal germs. And those which are the primal germs of things No power can quench; for in the end they conquer By their own solidness; though hard it be To think that aught in things has solid frame; For lightnings pass, no less than voice and shout, Through hedging walls of houses, and the iron White-dazzles in the fire, and rocks will burn With exhalations fierce and burst asunder. Totters the rigid gold dissolved in heat; The ice of bronze melts conquered in the flame; Warmth and the piercing cold through silver seep, Since, with the cups held rightly in the hand, We oft feel both, as from above is poured The dew of waters between their shining sides: So true it is no solid form is found. But yet because true reason and nature of things Constrain us, come, whilst in few verses now I disentangle how there still exist Bodies of solid, everlasting frame- The seeds of things, the primal germs we teach, Whence all creation around us came to be. First since we know a twofold nature exists, Of things, both twain and utterly unlike- Body, and place in which an things go on- Then each must be both for and through itself, And all unmixed: where'er be empty space, There body's not; and so where body bides, There not at an exists the void inane. Thus primal bodies are solid, without a void. But since there's void in all begotten things, All solid matter must be round the same; Nor, by true reason canst thou prove aught hides And holds a void within its body, unless Thou grant what holds it be a solid. Know, That which can hold a void of things within Can be naught else than matter in union knit. Thus matter, consisting of a solid frame, Hath power to be eternal, though all else, Though all creation, be dissolved away. Again, were naught of empty and inane, The world were then a solid; as, without Some certain bodies to fill the places held, The world that is were but a vacant void. And so, infallibly, alternate-wise Body and void are still distinguished, Since nature knows no wholly full nor void. There are, then, certain bodies, possessed of power To vary forever the empty and the full; And these can nor be sundered from without By beats and blows, nor from within be torn By penetration, nor be overthrown By any assault soever through the world- For without void, naught can be crushed, it seems, Nor broken, nor severed by a cut in twain, Nor can it take the damp, or seeping cold Or piercing fire, those old destroyers three; But the more void within a thing, the more Entirely it totters at their sure assault. Thus if first bodies be, as I have taught, Solid, without a void, they must be then Eternal; and, if matter ne'er had been Eternal, long ere now had all things gone Back into nothing utterly, and all We see around from nothing had been born- But since I taught above that naught can be From naught created, nor the once begotten To naught be summoned back, these primal germs Must have an immortality of frame. And into these must each thing be resolved, When comes its supreme hour, that thus there be At hand the stuff for plenishing the world.

So primal germs have solid singleness Nor otherwise could they have been conserved Through aeons and infinity of time For the replenishment of wasted worlds.
