Of space much vaster, in the self-same time
The sun’s effulgence widens round the sky.
Nor to pursue the atoms one by one,
To see the law whereby each thing goes on.
But some men, ignorant of matter, think,
Opposing this, that not without the gods,
In such adjustment to our human ways,
Can nature change the seasons of the years,
And bring to birth the grains and all of else
To which divine Delight, the guide of life,
Persuades mortality and leads it on,
That, through her artful blandishments of love,
It propagate the generations still,
Lest humankind should perish. When they feign
That gods have stablished all things but for man,
They seem in all ways mightily to lapse
From reason’s truth: for ev’n if ne’er I knew
What seeds primordial are, yet would I dare
This to affirm, ev’n from deep judgment based
Upon the ways and conduct of the skies —
This to maintain by many a fact besides —
That in no wise the nature of the world
For us was builded by a power divine —
So great the faults it stands encumbered with:
The which, my Memmius, later on, for thee
We will clear up. Now as to what remains
Concerning motions we’ll unfold our thought.
Now is the place, meseems, in these affairs
To prove for thee this too: nothing corporeal
Of its own force can e’er be upward borne,
Or upward go — nor let the bodies of flames
Deceive thee here: for they engendered are
With urge to upwards, taking thus increase,
Whereby grow upwards shining grains and trees,
Though all the weight within them downward bears.
Nor, when the fires will leap from under round
The roofs of houses, and swift flame laps up
Timber and beam, ’tis then to be supposed
They act of own accord, no force beneath
To urge them up. ’Tis thus that blood, discharged
From out our bodies, spurts its jets aloft
And spatters gore. And hast thou never marked
With what a force the water will disgorge
Timber and beam? The deeper, straight and down,
We push them in, and, many though we be,
The more we press with main and toil, the more
The water vomits up and flings them back,
That, more than half their length, they there emerge,
Rebounding. Yet we never doubt, meseems,
That all the weight within them downward bears
Through empty void. Well, in like manner, flames
Ought also to be able, when pressed out,
Through winds of air to rise aloft, even though
The weight within them strive to draw them down.
Hast thou not seen, sweeping so far and high,
The meteors, midnight flambeaus of the sky,
How after them they draw long trails of flame
Wherever Nature gives a thoroughfare?
How stars and constellations drop to earth,
Seest not? Nay, too, the sun from peak of heaven
Sheds round to every quarter its large heat,
And sows the new-ploughed intervales with light:
Thus also sun’s heat downward tends to earth.
Athwart the rain thou seest the lightning fly;
Now here, now there, bursting from out the clouds,
The fires dash zig-zag — and that flaming power
Falls likewise down to earth.
In these affairs
We wish thee also well aware of this:
The atoms, as their own weight bears them down
Plumb through the void, at scarce determined times,
In scarce determined places, from their course
Decline a little — call it, so to speak,
Mere changed trend. For were it not their wont
Thuswise to swerve, down would they fall, each one,
Like drops of rain, through the unbottomed void;
And then collisions ne’er could be nor blows
Among the primal elements; and thus
Nature would never have created aught.
But, if perchance be any that believe
The heavier bodies, as more swiftly borne
Plumb down the void, are able from above
To strike the lighter, thus engendering blows
Able to cause those procreant motions, far
From highways of true reason they retire.
For whatsoever through the waters fall,
Or through thin air, must quicken their descent,
Each after its weight — on this account, because
Both bulk of water and the subtle air
By no means can retard each thing alike,
But give more quick before the heavier weight;
But contrariwise the empty void cannot,
On any side, at any time, to aught
Oppose resistance, but will ever yield,
True to its bent of nature. Wherefore all,
With equal speed, though equal not in weight,
Must rush, borne downward through the still inane.
Thus ne’er at all have heavier from above
Been swift to strike the lighter, gendering strokes
Which cause those divers motions, by whose means
Nature transacts her work. And so I say,
The atoms must a little swerve at times —
But only the least, lest we should seem to feign
Motions oblique, and fact refute us there.
For this we see forthwith is manifest:
Whatever the weight, it can’t obliquely go,
Down on its headlong journey from above,
At least so far as thou canst mark; but who
Is there can mark by sense that naught can swerve
At all aside from off its road’s straight line?
Again, if ev’r all motions are co-linked,
And from the old ever arise the new
In fixed order, and primordial seeds
Produce not by their swerving some new start
Of motion to sunder the covenants of fate,
That cause succeed not cause from everlasting,
Whence this free will for creatures o’er the lands,
Whence is it wrested from the fates, — this will
Whereby we step right forward where desire
Leads each man on, whereby the same we swerve
In motions, not as at some fixed time,
Nor at some fixed line of space, but where
The mind itself has urged? For out of doubt
In these affairs ’tis each man’s will itself
That gives the start, and hence throughout our limbs
Incipient motions are diffused. Again,
Dost thou not see, when, at a point of time,
The bars are opened, how the eager strength
Of horses cannot forward break as soon
As pants their mind to do? For it behooves
That all the stock of matter, through the frame,
Be roused, in order that, through every joint,
Aroused, it press and follow mind’s desire;
So thus thou seest initial motion’s gendered
From out the heart, aye, verily, proceeds
First from the spirit’s will, whence at the last
’Tis given forth through joints and body entire.
Quite otherwise it is, when forth we move,
Impelled by a blow of another’s mighty powers
And mighty urge; for then ’tis clear enough
All matter of our total body goes,
Hurried along, against our own desire —
/>
Until the will has pulled upon the reins
And checked it back, throughout our members all;
At whose arbitrament indeed sometimes
The stock of matter’s forced to change its path,
Throughout our members and throughout our joints,
And, after being forward cast, to be
Reined up, whereat it settles back again.
So seest thou not, how, though external force
Drive men before, and often make them move,
Onward against desire, and headlong snatched,
Yet is there something in these breasts of ours
Strong to combat, strong to withstand the same? —
Wherefore no less within the primal seeds
Thou must admit, besides all blows and weight,
Some other cause of motion, whence derives
This power in us inborn, of some free act. —
Since naught from nothing can become, we see.
For weight prevents all things should come to pass
Through blows, as ‘twere, by some external force;
But that man’s mind itself in all it does
Hath not a fixed necessity within,
Nor is not, like a conquered thing, compelled
To bear and suffer, — this state comes to man
From that slight swervement of the elements
In no fixed line of space, in no fixed time.
Nor ever was the stock of stuff more crammed,
Nor ever, again, sundered by bigger gaps:
For naught gives increase and naught takes away;
On which account, just as they move to-day,
The elemental bodies moved of old
And shall the same hereafter evermore.
And what was wont to be begot of old
Shall be begotten under selfsame terms
And grow and thrive in power, so far as given
To each by Nature’s changeless, old decrees.
The sum of things there is no power can change,
For naught exists outside, to which can flee
Out of the world matter of any kind,
Nor forth from which a fresh supply can spring,
Break in upon the founded world, and change
Whole nature of things, and turn their motions about.
ATOMIC FORMS AND THEIR COMBINATIONS
Now come, and next hereafter apprehend
What sorts, how vastly different in form,
How varied in multitudinous shapes they are —
These old beginnings of the universe;
Not in the sense that only few are furnished
With one like form, but rather not at all
In general have they likeness each with each,
No marvel: since the stock of them’s so great
That there’s no end (as I have taught) nor sum,
They must indeed not one and all be marked
By equal outline and by shape the same.
Moreover, humankind, and the mute flocks
Of scaly creatures swimming in the streams,
And joyous herds around, and all the wild,
And all the breeds of birds — both those that teem
In gladsome regions of the water-haunts,
About the river-banks and springs and pools,
And those that throng, flitting from tree to tree,
Through trackless woods — Go, take which one thou wilt,
In any kind: thou wilt discover still
Each from the other still unlike in shape.
Nor in no other wise could offspring know
Mother, nor mother offspring — which we see
They yet can do, distinguished one from other,
No less than human beings, by clear signs.
Thus oft before fair temples of the gods,
Beside the incense-burning altars slain,
Drops down the yearling calf, from out its breast
Breathing warm streams of blood; the orphaned mother,
Ranging meanwhile green woodland pastures round,
Knows well the footprints, pressed by cloven hoofs,
With eyes regarding every spot about,
For sight somewhere of youngling gone from her;
And, stopping short, filleth the leafy lanes
With her complaints; and oft she seeks again
Within the stall, pierced by her yearning still.
Nor tender willows, nor dew-quickened grass,
Nor the loved streams that glide along low banks,
Can lure her mind and turn the sudden pain;
Nor other shapes of calves that graze thereby
Distract her mind or lighten pain the least —
So keen her search for something known and hers.
Moreover, tender kids with bleating throats
Do know their horned dams, and butting lambs
The flocks of sheep, and thus they patter on,
Unfailingly each to its proper teat,
As nature intends. Lastly, with any grain,
Thou’lt see that no one kernel in one kind
Is so far like another, that there still
Is not in shapes some difference running through.
By a like law we see how earth is pied
With shells and conchs, where, with soft waves, the sea
Beats on the thirsty sands of curving shores.
Wherefore again, again, since seeds of things
Exist by nature, nor were wrought with hands
After a fixed pattern of one other,
They needs must flitter to and fro with shapes
In types dissimilar to one another.
Easy enough by thought of mind to solve
Why fires of lightning more can penetrate
Than these of ours from pitch-pine born on earth.
For thou canst say lightning’s celestial fire,
So subtle, is formed of figures finer far,
And passes thus through holes which this our fire,
Born from the wood, created from the pine,
Cannot. Again, light passes through the horn
On the lantern’s side, while rain is dashed away.
And why? — unless those bodies of light should be
Finer than those of water’s genial showers.
We see how quickly through a colander
The wines will flow; how, on the other hand,
The sluggish olive-oil delays: no doubt,
Because ’tis wrought of elements more large,
Or else more crook’d and intertangled. Thus
It comes that the primordials cannot be
So suddenly sundered one from other, and seep,
One through each several hole of anything.
And note, besides, that liquor of honey or milk
Yields in the mouth agreeable taste to tongue,
Whilst nauseous wormwood, pungent centaury,
With their foul flavour set the lips awry;
Thus simple ’tis to see that whatsoever
Can touch the senses pleasingly are made
Of smooth and rounded elements, whilst those
Which seem the bitter and the sharp, are held
Entwined by elements more crook’d, and so
Are wont to tear their ways into our senses,
And rend our body as they enter in.
In short all good to sense, all bad to touch,
Being up-built of figures so unlike,
Are mutually at strife — lest thou suppose
That the shrill rasping of a squeaking saw
Consists of elements as smooth as song
Which, waked by nimble fingers, on the strings
The sweet musicians fashion; or suppose
That same-shaped atoms through men’s nostrils pierce
When foul cadavers burn, as when the stage
Is with Cilician saffron sprinkled fresh,
And the altar near exhales Panchaean scent;
O
r hold as of like seed the goodly hues
Of things which feast our eyes, as those which sting
Against the smarting pupil and draw tears,
Or show, with gruesome aspect, grim and vile.
For never a shape which charms our sense was made
Without some elemental smoothness; whilst
Whate’er is harsh and irksome has been framed
Still with some roughness in its elements.
Some, too, there are which justly are supposed
To be nor smooth nor altogether hooked,
With bended barbs, but slightly angled-out,
To tickle rather than to wound the sense —
And of which sort is the salt tartar of wine
And flavours of the gummed elecampane.
Again, that glowing fire and icy rime
Are fanged with teeth unlike whereby to sting
Our body’s sense, the touch of each gives proof.
For touch — by sacred majesties of Gods! —
Touch is indeed the body’s only sense —
Be’t that something in-from-outward works,
Be’t that something in the body born
Wounds, or delighteth as it passes out
Along the procreant paths of Aphrodite;
Or be’t the seeds by some collision whirl
Disordered in the body and confound
By tumult and confusion all the sense —
As thou mayst find, if haply with the hand
Thyself thou strike thy body’s any part.
On which account, the elemental forms
Must differ widely, as enabled thus
To cause diverse sensations.
And, again,
What seems to us the hardened and condensed
Must be of atoms among themselves more hooked,
Be held compacted deep within, as ‘twere
By branch-like atoms — of which sort the chief
Are diamond stones, despisers of all blows,
And stalwart flint and strength of solid iron,
And brazen bars, which, budging hard in locks,
Do grate and scream. But what are liquid, formed
Of fluid body, they indeed must be
Of elements more smooth and round — because
Their globules severally will not cohere:
To suck the poppy-seeds from palm of hand
Is quite as easy as drinking water down,
And they, once struck, roll like unto the same.
But that thou seest among the things that flow
Some bitter, as the brine of ocean is,
Is not the least a marvel...
For since ’tis fluid, smooth its atoms are
And round, with painful rough ones mixed therein;
