On the Nature of Things

Titus Lucretius Carus

The stock of stuff, dissolved, would be borne Along the illimitable inane afar, Or rather, in fact, would ne'er have once combined And given a birth to aught, since, scattered wide, It could not be united. For of truth Neither by counsel did the primal germs 'Stablish themselves, as by keen act of mind, Each in its proper place; nor did they make, Forsooth, a compact how each germ should move; But since, being many and changed in many modes Along the All, they're driven abroad and vexed By blow on blow, even from all time of old, They thus at last, after attempting all The kinds of motion and conjoining, come Into those great arrangements out of which This sum of things established is create, By which, moreover, through the mighty years, It is preserved, when once it has been thrown Into the proper motions, bringing to pass That ever the streams refresh the greedy main With river-waves abounding, and that earth, Lapped in warm exhalations of the sun, Renews her broods, and that the lusty race Of breathing creatures bears and blooms, and that The gliding fires of ether are alive-- What still the primal germs nowise could do, Unless from out the infinite of space Could come supply of matter, whence in season They're wont whatever losses to repair. For as the nature of breathing creatures wastes, Losing its body, when deprived of food: So all things have to be dissolved as soon As matter, diverted by what means soever From off its course, shall fail to be on hand. Nor can the blows from outward still conserve, On every side, whatever sum of a world Has been united in a whole. They can Indeed, by frequent beating, check a part, Till others arriving may fulfil the sum; But meanwhile often are they forced to spring Rebounding back, and, as they spring, to yield, Unto those elements whence a world derives, Room and a time for flight, permitting them To be from off the massy union borne Free and afar. Wherefore, again, again: Needs must there come a many for supply; And also, that the blows themselves shall be Unfailing ever, must there ever be An infinite force of matter all sides round. And in these problems, shrink, my Memmius, far From yielding faith to that notorious talk: That all things inward to the centre press; And thus the nature of the world stands firm With never blows from outward, nor can be Nowhere disparted--since all height and depth Have always inward to the centre pressed (If thou art ready to believe that aught Itself can rest upon itself ); or that The ponderous bodies which be under earth Do all press upwards and do come to rest Upon the earth, in some way upside down, Like to those images of things we see At present through the waters. They contend, With like procedure, that all breathing things Head downward roam about, and yet cannot Tumble from earth to realms of sky below, No more than these our bodies wing away Spontaneously to vaults of sky above; That, when those creatures look upon the sun, We view the constellations of the night; And that with us the seasons of the sky They thus alternately divide, and thus Do pass the night coequal to our days, But a vain error has given these dreams to fools, Which they've embraced with reasoning perverse For centre none can be where world is still Boundless, nor yet, if now a centre were, Could aught take there a fixed position more Than for some other cause 'tmight be dislodged. For all of room and space we call the void Must both through centre and non-centre yield Alike to weights where'er their motions tend. Nor is there any place, where, when they've come, Bodies can be at standstill in the void, Deprived of force of weight; nor yet may void Furnish support to any,--nay, it must, True to its bent of nature, still give way. Thus in such manner not at all can things Be held in union, as if overcome By craving for a centre. But besides, Seeing they feign that not all bodies press To centre inward, rather only those Of earth and water (liquid of the sea, And the big billows from the mountain slopes, And whatsoever are encased, as 'twere, In earthen body), contrariwise, they teach How the thin air, and with it the hot fire, Is borne asunder from the centre, and how, For this all ether quivers with bright stars, And the sun's flame along the blue is fed (Because the heat, from out the centre flying, All gathers there), and how, again, the boughs Upon the tree-tops could not sprout their leaves, Unless, little by little, from out the earth For each were nutriment... ***** Lest, after the manner of the winged flames, The ramparts of the world should flee away, Dissolved amain throughout the mighty void, And lest all else should likewise follow after, Aye, lest the thundering vaults of heaven should burst And splinter upward, and the earth forthwith Withdraw from under our feet, and all its bulk, Among its mingled wrecks and those of heaven, With slipping asunder of the primal seeds, Should pass, along the immeasurable inane, Away forever, and, that instant, naught Of wrack and remnant would be left, beside The desolate space, and germs invisible. For on whatever side thou deemest first The primal bodies lacking, lo, that side Will be for things the very door of death: Wherethrough the throng of matter all will dash, Out and abroad. These points, if thou wilt ponder, Then, with but paltry trouble led along... ***** For one thing after other will grow clear, Nor shall the blind night rob thee of the road, To hinder thy gaze on nature's Farthest-forth. Thus things for things shall kindle torches new. BOOK II PROEM 'Tis sweet, when, down the mighty main, the winds Roll up its waste of waters, from the land To watch another's labouring anguish far, Not that we joyously delight that man Should thus be smitten, but because 'tis sweet To mark what evils we ourselves be spared; 'Tis sweet, again, to view the mighty strife Of armies embattled yonder o'er the plains, Ourselves no sharers in the peril; but naught There is more goodly than to hold the high Serene plateaus, well fortressed by the wise, Whence thou may'st look below on other men And see them ev'rywhere wand'ring, all dispersed In their lone seeking for the road of life; Rivals in genius, or emulous in rank, Pressing through days and nights with hugest toil For summits of power and mastery of the world. O wretched minds of men! O blinded hearts! In how great perils, in what darks of life Are spent the human years, however brief!-- O not to see that nature for herself Barks after nothing, save that pain keep off, Disjoined from the body, and that mind enjoy Delightsome feeling, far from care and fear! Therefore we see that our corporeal life Needs little, altogether, and only such As takes the pain away, and can besides Strew underneath some number of delights. More grateful 'tis at times (for nature craves No artifice nor luxury), if forsooth There be no golden images of boys Along the halls, with right hands holding out The lamps ablaze, the lights for evening feasts, And if the house doth glitter not with gold Nor gleam with silver, and to the lyre resound No fretted and gilded ceilings overhead, Yet still to lounge with friends in the soft grass Beside a river of water, underneath A big tree's boughs, and merrily to refresh Our frames, with no vast outlay--most of all If the weather is laughing and the times of the year Besprinkle the green of the grass around with flowers. Nor yet the quicker will hot fevers go, If on a pictured tapestry thou toss, Or purple robe, than if 'tis thine to lie Upon the poor man's bedding. Wherefore, since Treasure, nor rank, nor glory of a reign Avail us naught for this our body, thus Reckon them likewise nothing for the mind: Save then perchance, when thou beholdest forth Thy legions swarming round the Field of Mars, Rousing a mimic warfare--either side Strengthened with large auxiliaries and horse, Alike equipped with arms, alike inspired; Or save when also thou beholdest forth Thy fleets to swarm, deploying down the sea: For then, by such bright circumstance abashed, Religion pales and flees thy mind; O then The fears of death leave heart so free of care. But if we note how all this pomp at last Is but a drollery and a mocking sport, And of a truth man's dread, with cares at heels, Dreads not these sounds of arms, these savage swords But among kings and lords of all the world Mingles undaunted, nor is overawed By gleam of gold nor by the splendour bright Of purple robe, canst thou then doubt that this Is aught, but power of thinking?--when, besides The whole of life but labours in the dark. For just as children tremble and fear all In the viewless dark, so even we at times Dread in the light so many things that be No whit more fearsome than what children feign, Shuddering, will be upon them in the dark. This terror then, this darkness of the mind, Not sunrise with its flaring spokes of light, Nor glittering arrows of morning can disperse, But only nature's aspect and her law. ATOMIC MOTIONS Now come: I will untangle for thy steps Now by what motions the begetting bodies Of the world-stuff beget the varied world, And then forever resolve it when begot, And by what force they are constrained to this, And what the speed appointed unto them Wherewith to travel down the vast inane: Do thou remember to yield thee to my words. For truly matter coheres not, crowds not tight, Since we behold each thing to wane away, And we observe how all flows on and off, As 'twere, with age-old time, and from our eyes How eld withdraws each object at the end, Albeit the sum is seen to bide the same, Unharmed, because these motes that leave each thing Diminish what they part from, but endow With increase those to which in turn they come, Constraining these to wither in old age, And those to flower at the prime (and yet Biding not long among them). Thus the sum Forever is replenished, and we live As mortals by eternal give and take. The nations wax, the nations wane away; In a brief space the generations pass, And like to runners hand the lamp of life One unto other. But if thou believe That the primordial germs of things can stop, And in their stopping give new motions birth, Afar thou wanderest from the road of truth. For since they wander through the void inane, All the primordial germs of things must needs Be borne along, either by weight their own, Or haply by another's blow without.
