And this same argument establisheth
That nature of mind and soul corporeal is:
For when 'tis seen to drive the members on,
To snatch from sleep the body, and to change
The countenance, and the whole state of man
To rule and turn,--what yet could never be
Sans contact, and sans body contact fails--
Must we not grant that mind and soul consist
Of a corporeal nature? --And besides
Thou markst that likewise with this body of ours
Suffers the mind and with our body feels.
If the dire speed of spear that cleaves the bones
And bares the inner thews hits not the life,
Yet follows a fainting and a foul collapse,
And, on the ground, dazed tumult in the mind,
And whiles a wavering will to rise afoot.
So nature of mind must be corporeal, since
From stroke and spear corporeal 'tis in throes.

Now, of what body, what components formed
Is this same mind I will go on to tell.
First, I aver, 'tis superfine, composed
Of tiniest particles--that such the fact
Thou canst perceive, if thou attend, from this:
Nothing is seen to happen with such speed
As what the mind proposes and begins;
Therefore the same bestirs itself more swiftly
Than aught whose nature's palpable to eyes.
But what's so agile must of seeds consist
Most round, most tiny, that they may be moved,
When hit by impulse slight. So water moves,
In waves along, at impulse just the least--
Being create of little shapes that roll;
But, contrariwise, the quality of honey
More stable is, its liquids more inert,
More tardy its flow; for all its stock of matter
Cleaves more together, since, indeed, 'tis made
Of atoms not so smooth, so fine, and round.
For the light breeze that hovers yet can blow
High heaps of poppy-seed away for thee
Downward from off the top; but, contrariwise,
A pile of stones or spiny ears of wheat
It can't at all. Thus, in so far as bodies
Are small and smooth, is their mobility;
But, contrariwise, the heavier and more rough,
The more immovable they prove. Now, then,
Since nature of mind is movable so much,
Consist it must of seeds exceeding small
And smooth and round. Which fact once known to thee,
Good friend, will serve thee opportune in else.
This also shows the nature of the same,
How nice its texture, in how small a space
'Twould go, if once compacted as a pellet:
When death's unvexed repose gets hold on man
And mind and soul retire, thou markest there
From the whole body nothing ta'en in form,
Nothing in weight. Death grants ye everything,
But vital sense and exhalation hot.
Thus soul entire must be of smallmost seeds,
Twined through the veins, the vitals, and the thews,
Seeing that, when 'tis from whole body gone,
The outward figuration of the limbs
Is unimpaired and weight fails not a whit.
Just so, when vanished the bouquet of wine,
Or when an unguent's perfume delicate
Into the winds away departs, or when
From any body savour's gone, yet still
The thing itself seems minished naught to eyes,
Thereby, nor aught abstracted from its weight--
No marvel, because seeds many and minute
Produce the savours and the redolence
In the whole body of the things. And so,
Again, again, nature of mind and soul
'Tis thine to know created is of seeds
The tiniest ever, since at flying-forth
It beareth nothing of the weight away.

Yet fancy not its nature simple so.
For an impalpable aura, mixed with heat,
Deserts the dying, and heat draws off the air;
And heat there's none, unless commixed with air:
For, since the nature of all heat is rare,
Athrough it many seeds of air must move.
Thus nature of mind is triple; yet those all
Suffice not for creating sense--since mind
Accepteth not that aught of these can cause
Sense-bearing motions, and much less the thoughts
A man revolves in mind. So unto these
Must added be a somewhat, and a fourth;
That somewhat's altogether void of name;
Than which existeth naught more mobile, naught
More an impalpable, of elements
More small and smooth and round. That first transmits
Sense-bearing motions through the frame, for that
Is roused the first, composed of little shapes;
Thence heat and viewless force of wind take up
The motions, and thence air, and thence all things
Are put in motion; the blood is strook, and then
The vitals all begin to feel, and last
To bones and marrow the sensation comes--
Pleasure or torment. Nor will pain for naught
Enter so far, nor a sharp ill seep through,
But all things be perturbed to that degree
That room for life will fail, and parts of soul
Will scatter through the body's every pore.
Yet as a rule, almost upon the skin
These motion aIl are stopped, and this is why
We have the power to retain our life.

Now in my eagerness to tell thee how
They are commixed, through what unions fit
They function so, my country's pauper-speech
Constrains me sadly. As I can, however,
I'll touch some points and pass. In such a wise
Course these primordials 'mongst one another
With inter-motions that no one can be
From other sundered, nor its agency
Perform, if once divided by a space;
Like many powers in one body they work.
As in the flesh of any creature still
Is odour and savour and a certain warmth,
And yet from all of these one bulk of body
Is made complete, so, viewless force of wind
And warmth and air, commingled, do create
One nature, by that mobile energy
Assisted which from out itself to them
Imparts initial motion, whereby first
Sense-bearing motion along the vitals springs.
For lurks this essence far and deep and under,
Nor in our body is aught more shut from view,
And 'tis the very soul of all the soul.
And as within our members and whole frame
The energy of mind and power of soul
Is mixed and latent, since create it is
Of bodies small and few, so lurks this fourth,
This essence void of name, composed of small,
And seems the very soul of all the soul,
And holds dominion o'er the body all.
And by like reason wind and air and heat
Must function so, commingled through the frame,
And now the one subside and now another
In interchange of dominance, that thus
From all of them one nature be produced,
Lest heat and wind apart, and air apart,
Make sense to perish, by disseverment.
