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.

For, when, in their incessancy so oft

They meet and clash, it comes to pass amain

They leap asunder, face to face: not strange—

Being most hard, and solid in their weights,

And naught opposing motion, from behind.

And that more clearly thou perceive how all

These mites of matter are darted round about,

Recall to mind how nowhere in the sum

Of All exists a bottom,—nowhere is

A realm of rest for primal bodies; since

(As amply shown and proved by reason sure)

Space has no bound nor measure, and extends

Unmetered forth in all directions round.

Since this stands certain, thus 'tis out of doubt

No rest is rendered to the primal bodies

Along the unfathomable inane; but rather,

Inveterately plied by motions mixed,

Some, at their jamming, bound aback and leave

Huge gaps between, and some from off the blow

Are hurried about with spaces small between.

And all which, brought together with slight gaps,

In more condensed union bound aback,

Linked by their own all inter-tangled shapes,—

These form the irrefragable roots of rocks

And the brute bulks of iron, and what else

Is of their kind...

The rest leap far asunder, far recoil,

Leaving huge gaps between: and these supply

For us thin air and splendour-lights of the sun.

And many besides wander the mighty void—

Cast back from unions of existing things,

Nowhere accepted in the universe,

And nowise linked in motions to the rest.

And of this fact (as I record it here)

An image, a type goes on before our eyes

Present each moment; for behold whenever

The sun's light and the rays, let in, pour down

Across dark halls of houses: thou wilt see

The many mites in many a manner mixed

Amid a void in the very light of the rays,

And battling on, as in eternal strife,

And in battalions contending without halt,

In meetings, partings, harried up and down.

From this thou mayest conjecture of what sort

The ceaseless tossing of primordial seeds

Amid the mightier void—at least so far

As small affair can for a vaster serve,

And by example put thee on the spoor

Of knowledge. For this reason too 'tis fit

Thou turn thy mind the more unto these bodies

Which here are witnessed tumbling in the light:

Namely, because such tumblings are a sign

That motions also of the primal stuff

Secret and viewless lurk beneath, behind.

For thou wilt mark here many a speck, impelled

By viewless blows, to change its little course,

And beaten backwards to return again,

Hither and thither in all directions round.

Lo, all their shifting movement is of old,

From the primeval atoms; for the same

Primordial seeds of things first move of self,

And then those bodies built of unions small

And nearest, as it were, unto the powers

Of the primeval atoms, are stirred up

By impulse of those atoms' unseen blows,

And these thereafter goad the next in size:

Thus motion ascends from the primevals on,

And stage by stage emerges to our sense,

Until those objects also move which we

Can mark in sunbeams, though it not appears

What blows do urge them.

Herein wonder not

How 'tis that, while the seeds of things are all

Moving forever, the sum yet seems to stand

Supremely still, except in cases where

A thing shows motion of its frame as whole.

For far beneath the ken of senses lies

The nature of those ultimates of the world;

And so, since those themselves thou canst not see,

Their motion also must they veil from men—

For mark, indeed, how things we can see, oft

Yet hide their motions, when afar from us

Along the distant landscape. Often thus,

Upon a hillside will the woolly flocks

Be cropping their goodly food and creeping about

Whither the summons of the grass, begemmed

With the fresh dew, is calling, and the lambs,

Well filled, are frisking, locking horns in sport:

Yet all for us seem blurred and blent afar—

A glint of white at rest on a green hill.

Again, when mighty legions, marching round,

Fill all the quarters of the plains below,

Rousing a mimic warfare, there the sheen

Shoots up the sky, and all the fields about

Glitter with brass, and from beneath, a sound

Goes forth from feet of stalwart soldiery,

And mountain walls, smote by the shouting, send

The voices onward to the stars of heaven,

And hither and thither darts the cavalry,

And of a sudden down the midmost fields

Charges with onset stout enough to rock

The solid earth: and yet some post there is

Up the high mountains, viewed from which they seem

To stand—a gleam at rest along the plains.

Now what the speed to matter's atoms given

Thou mayest in few, my Memmius, learn from this:

When first the dawn is sprinkling with new light

The lands, and all the breed of birds abroad

Flit round the trackless forests, with liquid notes

Filling the regions along the mellow air,

We see 'tis forthwith manifest to man

How suddenly the risen sun is wont

At such an hour to overspread and clothe

The whole with its own splendour; but the sun's

Warm exhalations and this serene light

Travel not down an empty void; and thus

They are compelled more slowly to advance,

Whilst, as it were, they cleave the waves of air;

Nor one by one travel these particles

Of the warm exhalations, but are all

Entangled and enmassed, whereby at once

Each is restrained by each, and from without

Checked, till compelled more slowly to advance.

But the primordial atoms with their old

Simple solidity, when forth they travel

Along the empty void, all undelayed

By aught outside them there, and they, each one

Being one unit from nature of its parts,

Are borne to that one place on which they strive

Still to lay hold, must then, beyond a doubt,

Outstrip in speed, and be more swiftly borne

Than light of sun, and over regions rush,

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.
