Of The Nature Of Things: Book IV - Part 04 - Some Vital Functions

In these affairs
We crave that thou wilt passionately flee
The one offence, and anxiously wilt shun
The error of presuming the clear lights
Of eyes created were that we might see;
Or thighs and knees, aprop upon the feet,
Thuswise can bended be, that we might step
With goodly strides ahead; or forearms joined
Unto the sturdy uppers, or serving hands
On either side were given, that we might do
Life's own demands. All such interpretation
Is aft-for-fore with inverse reasoning,
Since naught is born in body so that we
May use the same, but birth engenders use:
No seeing ere the lights of eyes were born,
No speaking ere the tongue created was;
But origin of tongue came long before
Discourse of words, and ears created were
Much earlier than any sound was heard;
And all the members, so meseems, were there
Before they got their use: and therefore, they
Could not be gendered for the sake of use.
But contrariwise, contending in the fight
With hand to hand, and rending of the joints,
And fouling of the limbs with gore, was there,
O long before the gleaming spears ere flew;
And Nature prompted man to shun a wound,
Before the left arm by the aid of art
Opposed the shielding targe. And, verily,
Yielding the weary body to repose,
Far ancienter than cushions of soft beds,
And quenching thirst is earlier than cups.
These objects, therefore, which for use and life
Have been devised, can be conceived as found
For sake of using. But apart from such
Are all which first were born and afterwards
Gave knowledge of their own utility-
Chief in which sort we note the senses, limbs:
Wherefore, again, 'tis quite beyond thy power
To hold that these could thus have been create
For office of utility.
Likewise,
'Tis nothing strange that all the breathing creatures
Seek, even by nature of their frame, their food.
Yes, since I've taught thee that from off the things
Stream and depart innumerable bodies
In modes innumerable too; but most
Must be the bodies streaming from the living-
Which bodies, vexed by motion evermore,
Are through the mouth exhaled innumerable,
When weary creatures pant, or through the sweat
Squeezed forth innumerable from deep within.
Thus body rarefies, so undermined
In all its nature, and pain attends its state.
And so the food is taken to underprop
The tottering joints, and by its interfusion
To re-create their powers, and there stop up
The longing, open-mouthed through limbs and veins,
For eating. And the moist no less departs
Into all regions that demand the moist;
And many heaped-up particles of hot,
Which cause such burnings in these bellies of ours,
The liquid on arriving dissipates
And quenches like a fire, that parching heat
No longer now can scorch the frame. And so,
Thou seest how panting thirst is washed away
From off our body, how the hunger-pang
It, too, appeased.
Now, how it comes that we,
Whene'er we wish, can step with strides ahead,
And how 'tis given to move our limbs about,
And what device is wont to push ahead
This the big load of our corporeal frame,
I'll say to thee- do thou attend what's said.
I say that first some idol-films of walking
Into our mind do fall and smite the mind,
As said before. Thereafter will arises;
For no one starts to do a thing, before
The intellect previsions what it wills;
And what it there pre-visioneth depends
On what that image is. When, therefore, mind
Doth so bestir itself that it doth will
To go and step along, it strikes at once
That energy of soul that's sown about
In all the body through the limbs and frame-
And this is easy of performance, since
The soul is close conjoined with the mind.
Next, soul in turn strikes body, and by degrees
Thus the whole mass is pushed along and moved.
Then too the body rarefies, and air,
Forsooth as ever of such nimbleness,
Comes on and penetrates aboundingly
Through opened pores, and thus is sprinkled round
Unto all smallest places in our frame.
Thus then by these twain factors, severally,
Body is borne like ship with oars and wind.
Nor yet in these affairs is aught for wonder
That particles so fine can whirl around
So great a body and turn this weight of ours;
For wind, so tenuous with its subtle body,
Yet pushes, driving on the mighty ship
Of mighty bulk; one hand directs the same,
Whatever its momentum, and one helm
Whirls it around, whither ye please; and loads,
Many and huge, are moved and hoisted high
By enginery of pulley-blocks and wheels,
With but light strain.
Now, by what modes this sleep
Pours through our members waters of repose
And frees the breast from cares of mind, I'll tell
In verses sweeter than they many are;
Even as the swan's slight note is better far
Than that dispersed clamour of the cranes
Among the south wind's aery clouds. Do thou
Give me sharp ears and a sagacious mind,-
That thou mayst not deny the things to be
Whereof I'm speaking, nor depart away
With bosom scorning these the spoken truths,
Thyself at fault unable to perceive.
Sleep chiefly comes when energy of soul
Hath now been scattered through the frame, and part
Expelled abroad and gone away, and part
Crammed back and settling deep within the frame-
Whereafter then our loosened members droop.
For doubt is none that by the work of soul
Exist in us this sense, and when by slumber
That sense is thwarted, we are bound to think
The soul confounded and expelled abroad-
Yet not entirely, else the frame would lie
Drenched in the everlasting cold of death.
In sooth, where no one part of soul remained
Lurking among the members, even as fire
Lurks buried under many ashes, whence
Could sense amain rekindled be in members,
As flame can rise anew from unseen fire?
By what devices this strange state and new
May be occasioned, and by what the soul
Can be confounded and the frame grow faint,
I will untangle: see to it, thou, that I
Pour forth my words not unto empty winds.
In first place, body on its outer parts-
Since these are touched by neighbouring aery gusts-
Must there be thumped and strook by blows of air
Repeatedly. And therefore almost all
Are covered either with hides, or else with shells,
Or with the horny callus, or with bark.
Yet this same air lashes their inner parts,
When creatures draw a breath or blow it out.
Wherefore, since body thus is flogged alike
Upon the inside and the out, and blows
Come in upon us through the little pores
Even inward to our body's primal parts
And primal elements, there comes to pass
By slow degrees, along our members then,
A kind of overthrow; for then confounded
Are those arrangements of the primal germs
Of body and of mind. It comes to pass
That next a part of soul's expelled abroad,
A part retreateth in recesses hid,
A part, too, scattered all about the frame,
Cannot become united nor engage
In interchange of motion. Nature now
So hedges off approaches and the paths;
And thus the sense, its motions all deranged,
Retires down deep within; and since there's naught,
As 'twere, to prop the frame, the body weakens,
And all the members languish, and the arms
And eyelids fall, and, as ye lie abed,
Even there the houghs will sag and loose their powers.
Again, sleep follows after food, because
The food produces same result as air,
Whilst being scattered round through all the veins;
And much the heaviest is that slumber which,
Full or fatigued, thou takest; since 'tis then
That the most bodies disarrange themselves,
Bruised by labours hard. And in same wise,
This three-fold change: a forcing of the soul
Down deeper, more a casting-forth of it,
A moving more divided in its parts
And scattered more.
And to whate'er pursuit
A man most clings absorbed, or what the affairs
On which we theretofore have tarried much,
And mind hath strained upon the more, we seem
In sleep not rarely to go at the same.
The lawyers seem to plead and cite decrees,
Commanders they to fight and go at frays,
Sailors to live in combat with the winds,
And we ourselves indeed to make this book,
And still to seek the nature of the world
And set it down, when once discovered, here
In these my country's leaves. Thus all pursuits,
All arts in general seem in sleeps to mock
And master the minds of men. And whosoever
Day after day for long to games have given
Attention undivided, still they keep
(As oft we note), even when they've ceased to grasp
Those games with their own senses, open paths
Within the mind wherethrough the idol-films
Of just those games can come. And thus it is
For many a day thereafter those appear
Floating before the eyes, that even awake
They think they view the dancers moving round
Their supple limbs, and catch with both the ears
The liquid song of harp and speaking chords,
And view the same assembly on the seats,
And manifold bright glories of the stage-
So great the influence of pursuit and zest,
And of the affairs wherein 'thas been the wont
Of men to be engaged-nor only men,
But soothly all the animals. Behold,
Thou'lt see the sturdy horses, though outstretched,
Yet sweating in their sleep, and panting ever,
And straining utmost strength, as if for prize,
As if, with barriers opened now…
And hounds of huntsmen oft in soft repose
Yet toss asudden all their legs about,
And growl and bark, and with their nostrils sniff
The winds again, again, though indeed
They'd caught the scented foot-prints of wild beasts,
And, even when wakened, often they pursue
The phantom images of stags, as though
They did perceive them fleeing on before,
Until the illusion's shaken off and dogs
Come to themselves again. And fawning breed
Of house-bred whelps do feel the sudden urge
To shake their bodies and start from off the ground,
As if beholding stranger-visages.
And ever the fiercer be the stock, the more
In sleep the same is ever bound to rage.
But fleet the divers tribes of birds and vex
With sudden wings by night the groves of gods,
When in their gentle slumbers they have dreamed
Of hawks in chase, aswooping on for fight.
Again, the minds of mortals which perform
With mighty motions mighty enterprises,
Often in sleep will do and dare the same
In manner like. Kings take the towns by storm,
Succumb to capture, battle on the field,
Raise a wild cry as if their throats were cut
Even then and there. And many wrestle on
And groan with pains, and fill all regions round
With mighty cries and wild, as if then gnawed
By fangs of panther or of lion fierce.
Many amid their slumbers talk about
Their mighty enterprises, and have often
Enough become the proof of their own crimes.
Many meet death; many, as if headlong
From lofty mountains tumbling down to earth
With all their frame, are frenzied in their fright;
And after sleep, as if still mad in mind,
They scarce come to, confounded as they are
By ferment of their frame. The thirsty man,
Likewise, he sits beside delightful spring
Or river and gulpeth down with gaping throat
Nigh the whole stream. And oft the innocent young,
By sleep o'ermastered, think they lift their dress
By pail or public jordan and then void
The water filtered down their frame entire
And drench the Babylonian coverlets,
Magnificently bright. Again, those males
Into the surging channels of whose years
Now first has passed the seed (engendered
Within their members by the ripened days)
Are in their sleep confronted from without
By idol-images of some fair form-
Tidings of glorious face and lovely bloom,
Which stir and goad the regions turgid now
With seed abundant; so that, as it were
With all the matter acted duly out,
They pour the billows of a potent stream
And stain their garment.
And as said before,
That seed is roused in us when once ripe age
Has made our body strong…
As divers causes give to divers things
Impulse and irritation, so one force
In human kind rouses the human seed
To spurt from man. As soon as ever it issues,
Forced from its first abodes, it passes down
In the whole body through the limbs and frame,
Meeting in certain regions of our thews,
And stirs amain the genitals of man.
The goaded regions swell with seed, and then
Comes the delight to dart the same at what
The mad desire so yearns, and body seeks
That object, whence the mind by love is pierced.
For well-nigh each man falleth toward his wound,
And our blood spurts even toward the spot from whence
The stroke wherewith we are strook, and if indeed
The foe be close, the red jet reaches him.
Thus, one who gets a stroke from Venus' shafts-
Whether a boy with limbs effeminate
Assault him, or a woman darting love
From all her body- that one strains to get
Even to the thing whereby he's hit, and longs
To join with it and cast into its frame
The fluid drawn even from within its own.
For the mute craving doth presage delight.
