The stuff of things is fire； and out of fire
Alone the cosmic sum is formed； are seen
Mightily from true reason to have lapsed。
Of whom； chief leader to do battle； comes
That Heraclitus； famous for dark speech
Among the silly； not the serious Greeks
Who search for truth。 For dolts are ever prone
That to bewonder and adore which hides
Beneath distorted words； holding that true
Which sweetly tickles in their stupid ears；
Or which is rouged in finely finished phrase。
For how； I ask； can things so varied be；
If formed of fire； single and pure？ No whit
'Twould help for fire to be condensed or thinned；
If all the parts of fire did still preserve
But fire's own nature； seen before in gross。
The heat were keener with the parts compressed；
Milder； again； when severed or dispersed…
And more than this thou canst conceive of naught
That from such causes could become； much less
Might earth's variety of things be born
From any fires soever； dense or rare。
This too： if they suppose a void in things；
Then fires can be condensed and still left rare；
But since they see such opposites of thought
Rising against them； and are loath to leave
An unmixed void in things； they fear the steep
And lose the road of truth。 Nor do they see；
That； if from things we take away the void；
All things are then condensed； and out of all
One body made； which has no power to dart
Swiftly from out itself not anything…
As throws the fire its light and warmth around；
Giving thee proof its parts are not compact。
But if perhaps they think； in other wise；
Fires through their combinations can be quenched
And change their substance； very well： behold；
If fire shall spare to do so in no part；
Then heat will perish utterly and all；
And out of nothing would the world be formed。
For change in anything from out its bounds
Means instant death of that which was before；
And thus a somewhat must persist unharmed
Amid the world； lest all return to naught；
And； born from naught； abundance thrive anew。
Now since indeed there are those surest bodies
Which keep their nature evermore the same；
Upon whose going out and coming in
And changed order things their nature change；
And all corporeal substances transformed；
'Tis thine to know those primal bodies； then；
Are not of fire。 For 'twere of no avail
Should some depart and go away； and some
Be added new； and some be changed in order；
If still all kept their nature of old heat：
For whatsoever they created then
Would still in any case be only fire。
The truth； I fancy； this： bodies there are
Whose clashings； motions； order； posture； shapes
Produce the fire and which； by order changed；
Do change the nature of the thing produced；
And are thereafter nothing like to fire
Nor whatso else has power to send its bodies
With impact touching on the senses' touch。
Again； to say that all things are but fire
And no true thing in number of all things
Exists but fire； as this same fellow says；
Seems crazed folly。 For the man himself
Against the senses by the senses fights；
And hews at that through which is all belief；
Through which indeed unto himself is known
The thing he calls the fire。 For； though he thinks
The senses truly can perceive the fire；
He thinks they cannot as regards all else；
Which still are palpably as clear to sense…
To me a thought inept and crazy too。
For whither shall we make appeal？ for what
More certain than our senses can there be
Whereby to mark asunder error and truth？
Besides； why rather do away with all；
And wish to allow heat only； then deny
The fire and still allow all else to be？…
Alike the madness either way it seems。
Thus whosoe'er have held the stuff of things
To be but fire； and out of fire the sum；
And whosoever have constituted air
As first beginning of begotten things；
And all whoever have held that of itself
Water alone contrives things； or that earth
Createth all and changes things anew
To divers natures； mightily they seem
A long way to have wandered from the truth。
Add； too； whoever make the primal stuff
Twofold； by joining air to fire； and earth
To water； add who deem that things can grow
Out of the four… fire； earth； and breath； and rain；
As first Empedocles of Acragas；
Whom that three…cornered isle of all the lands
Bore on her coasts； around which flows and flows
In mighty bend and bay the Ionic seas；
Splashing the brine from off their gray…green waves。
Here； billowing onward through the narrow straits；
Swift ocean cuts her boundaries from the shores
Of the Italic mainland。 Here the waste
Charybdis； and here Aetna rumbles threats
To gather anew such furies of its flames
As with its force anew to vomit fires；
Belched from its throat； and skyward bear anew
Its lightnings' flash。 And though for much she seem
The mighty and the wondrous isle to men；
Most rich in all good things； and fortified
With generous strength of heroes； she hath ne'er
Possessed within her aught of more renown；
Nor aught more holy； wonderful； and dear
Than this true man。 Nay； ever so far and pure
The lofty music of his breast divine
Lifts up its voice and tells of glories found；
That scarce he seems of human stock create。
Yet he and those forementioned （known to be
So far beneath him； less than he in all）；
Though； as discoverers of much goodly truth；
They gave； as 'twere from out of the heart's own shrine；
Responses holier and soundlier based
Than ever the Pythia pronounced for men
From out the triped and the Delphian laurel；
Have still in matter of first…elements
Made ruin of themselves； and； great men； great
Indeed and heavy there for them the fall：
First； because； banishing the void from things；
They yet assign them motion； and allow
Things soft and loosely textured to exist；
As air； dew； fire； earth； animals； and grains；
Without admixture of void amid their frame。
Next； because； thinking there can be no end
In cutting bodies down to less and less
Nor pause established to their breaking up；
They hold there is no minimum in things；
Albeit we see the boundary point of aught
Is that which to our senses seems its least；
Whereby thou mayst conjecture； that； because
The things thou canst not mark have boundary points；
They surely have their minimums。 Then； too；
Since these philosophers ascribe to things
Soft primal germs； which we behold to be
Of birth and body mortal； thus； throughout；
The sum of things must be returned to naught；
And； born from naught； abundance thrive anew…
Thou seest how far each doctrine stands from truth。
And； next； these bodies are among themselves
In many ways poisons and foes to each；
Wherefore their congress will destroy them quite
Or drive asunder as we see in storms
Rains； winds； and lightnings all asunder fly。
Thus too； if all things are create of four；
And all again dissolved into the four；
How can the four be called the primal germs
Of things； more than all things themselves be thought；
By retroversion； primal germs of them？
For ever alternately are both begot；
With interchange of nature and aspect
From immemorial time。 But if percase
Thou think'st the frame of fire and earth； the air；
The dew of water can in such wise meet
As not by mingling to resign their nature；
From them for thee no world can be create…
No thing of breath； no stock or stalk of tree：
In the wild congress of this varied heap
Each thing its proper nature will display；
And air will palpably be seen mixed up
With earth together； unquenched heat with water。
But primal germs in bringing things to birth
Must have a latent； unseen quality；
Lest some outstanding alien element
Confuse and minish in the thing create
Its proper being。
But these men begin
From heaven； and from its fires； and first they feign
That fire will turn into the winds of air；
Next； that from air the rain begotten is；
And earth created out of rain； and then
That all； reversely； are returned from earth…
The moisture first； then air thereafter heat…
And that these same ne'er cease in interchange；
To go their ways from heaven to earth； from earth
Unto the stars of the aethereal world…
Which in no wise at all the germs can do。
Since an immutable somewhat still must be；
Lest all things ut
