First, then, I say, the mind which oft we call
The intellect, wherein is seated life's
Counsel and regimen, is part no less
Of man than hand and foot and eyes are parts
Of one whole breathing creature. But some hold
That sense of mind is in no fixed part seated,
But is of body some one vital state,-
Named "harmony" by Greeks, because thereby
We live with sense, though intellect be not
In any part: as oft the body is said
To have good health (when health, however, 's not
One part of him who has it), so they place
The sense of mind in no fixed part of man.
Mightily, diversly, meseems they err.
Often the body palpable and seen
Sickens, while yet in some invisible part
We feel a pleasure; oft the other way,
A miserable in mind feels pleasure still
Throughout his body- quite the same as when
A foot may pain without a pain in head.
Besides, when these our limbs are given o'er
To gentle sleep and lies the burdened frame
At random void of sense, a something else
Is yet within us, which upon that time
Bestirs itself in many a wise, receiving
All motions of joy and phantom cares of heart.
Now, for to see that in man's members dwells
Also the soul, and body ne'er is wont
To feel sensation by a "harmony"
Take this in chief: the fact that life remains
Oft in our limbs, when much of body's gone;
Yet that same life, when particles of heat,
Though few, have scattered been, and through the mouth
Air has been given forth abroad, forthwith
Forever deserts the veins, and leaves the bones.
Thus mayst thou know that not all particles
Perform like parts, nor in like manner all
Are props of weal and safety: rather those-
The seeds of wind and exhalations warm-
Take care that in our members life remains.
Therefore a vital heat and wind there is
Within the very body, which at death
Deserts our frames. And so, since nature of mind
And even of soul is found to be, as 'twere,
A part of man, give over "harmony"-
Name to musicians brought from Helicon,-
Unless themselves they filched it otherwise,
To serve for what was lacking name till then.
Whate'er it be, they're welcome to it- thou,
Hearken my other maxims.
Mind and soul,
I say, are held conjoined one with other,
And form one single nature of themselves;
But chief and regnant through the frame entire
Is still that counsel which we call the mind,
And that cleaves seated in the midmost breast.
Here leap dismay and terror; round these haunts
Be blandishments of joys; and therefore here
The intellect, the mind. The rest of soul,
Throughout the body scattered, but obeys-
Moved by the nod and motion of the mind.
This, for itself, sole through itself, hath thought;
This for itself hath mirth, even when the thing
That moves it, moves nor soul nor body at all.
And as, when head or eye in us is smit
By assailing pain, we are not tortured then
Through all the body, so the mind alone
Is sometimes smitten, or livens with a joy,
Whilst yet the soul's remainder through the limbs
And through the frame is stirred by nothing new.
But when the mind is moved by shock more fierce,
We mark the whole soul suffering all at once
Along man's members: sweats and pallors spread
Over the body, and the tongue is broken,
And fails the voice away, and ring the ears,
Mists blind the eyeballs, and the joints collapse,-
Aye, men drop dead from terror of the mind.
Hence, whoso will can readily remark
That soul conjoined is with mind, and, when
'Tis strook by influence of the mind, forthwith
In turn it hits and drives the body too.

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,
