Of beasts； the mountain…rangers； when but once
They scent the certain footsteps of the way；
Thus thou thyself in themes like these alone
Can hunt from thought to thought； and keenly wind
Along even onward to the secret places
And drag out truth。 But； if thou loiter loth
Or veer； however little； from the point；
This I can promise； Memmius； for a fact：
Such copious drafts my singing tongue shall pour
From the large well…springs of my plenished breast
That much I dread slow age will steal and coil
Along our members； and unloose the gates
Of life within us； ere for thee my verse
Hath put within thine ears the stores of proofs
At hand for one soever question broached。
NOTHING EXISTS per se EXCEPT ATOMS AND THE VOID
But； now again to weave the tale begun；
All nature； then； as self…sustained； consists
Of twain of things： of bodies and of void
In which they're set； and where they're moved around。
For common instinct of our race declares
That body of itself exists： unless
This primal faith； deep…founded； fail us not；
Naught will there be whereunto to appeal
On things occult when seeking aught to prove
By reasonings of mind。 Again； without
That place and room； which we do call the inane；
Nowhere could bodies then be set； nor go
Hither or thither at all… as shown before。
Besides； there's naught of which thou canst declare
It lives disjoined from body； shut from void…
A kind of third in nature。 For whatever
Exists must be a somewhat； and the same；
If tangible； however fight and slight；
Will yet increase the count of body's sum；
With its own augmentation big or small；
But； if intangible and powerless ever
To keep a thing from passing through itself
On any side； 'twill be naught else but that
Which we do call the empty； the inane。
Again； whate'er exists； as of itself；
Must either act or suffer action on it；
Or else be that wherein things move and be：
Naught； saving body； acts； is acted on；
Naught but the inane can furnish room。 And thus；
Beside the inane and bodies； is no third
Nature amid the number of all things…
Remainder none to fall at any time
Under our senses； nor be seized and seen
By any man through reasonings of mind。
Name o'er creation with what names thou wilt；
Thou'lt find but properties of those first twain；
Or see but accidents those twain produce。
A property is that which not at all
Can be disjoined and severed from a thing
Without a fatal dissolution： such；
Weight to the rocks； heat to the fire； and flow
To the wide waters； touch to corporal things；
Intangibility to the viewless void。
But state of slavery； pauperhood； and wealth；
Freedom； and war； and concord； and all else
Which come and go whilst nature stands the same；
We're wont； and rightly； to call accidents。
Even time exists not of itself； but sense
Reads out of things what happened long ago；
What presses now； and what shall follow after：
No man； we must admit； feels time itself；
Disjoined from motion and repose of things。
Thus； when they say there 〃is〃 the ravishment
Of Princess Helen； 〃is〃 the siege and sack
Of Trojan Town； look out； they force us not
To admit these acts existent by themselves；
Merely because those races of mankind
（Of whom these acts were accidents） long since
Irrevocable age has borne away：
For all past actions may be said to be
But accidents； in one way； of mankind；…
In other； of some region of the world。
Add； too； had been no matter； and no room
Wherein all things go on； the fire of love
Upblown by that fair form； the glowing coal
Under the Phrygian Alexander's breast；
Had ne'er enkindled that renowned strife
Of savage war； nor had the wooden horse
Involved in flames old Pergama； by a birth
At midnight of a brood of the Hellenes。
And thus thou canst remark that every act
At bottom exists not of itself； nor is
As body is； nor has like name with void；
But rather of sort more fitly to be called
An accident of body； and of place
Wherein all things go on。
CHARACTER OF THE ATOMS
Bodies； again；
Are partly primal germs of things； and partly
Unions deriving from the primal germs。
And those which are the primal germs of things
No power can quench； for in the end they conquer
By their own solidness； though hard it be
To think that aught in things has solid frame；
For lightnings pass； no less than voice and shout；
Through hedging walls of houses； and the iron
White…dazzles in the fire； and rocks will burn
With exhalations fierce and burst asunder。
Totters the rigid gold dissolved in heat；
The ice of bronze melts conquered in the flame；
Warmth and the piercing cold through silver seep；
Since； with the cups held rightly in the hand；
We oft feel both； as from above is poured
The dew of waters between their shining sides：
So true it is no solid form is found。
But yet because true reason and nature of things
Constrain us； come； whilst in few verses now
I disentangle how there still exist
Bodies of solid； everlasting frame…
The seeds of things； the primal germs we teach；
Whence all creation around us came to be。
First since we know a twofold nature exists；
Of things； both twain and utterly unlike…
Body； and place in which an things go on…
Then each must be both for and through itself；
And all unmixed： where'er be empty space；
There body's not； and so where body bides；
There not at all exists the void inane。
Thus primal bodies are solid； without a void。
But since there's void in all begotten things；
All solid matter must be round the same；
Nor； by true reason canst thou prove aught hides
And holds a void within its body； unless
Thou grant what holds it be a solid。 Know；
That which can hold a void of things within
Can be naught else than matter in union knit。
Thus matter； consisting of a solid frame；
Hath power to be eternal； though all else；
Though all creation； be dissolved away。
Again； were naught of empty and inane；
The world were then a solid； as； without
Some certain bodies to fill the places held；
The world that is were but a vacant void。
And so； infallibly； alternate…wise
Body and void are still distinguished；
Since nature knows no wholly full nor void。
There are； then； certain bodies； possessed of power
To vary forever the empty and the full；
And these can nor be sundered from without
By beats and blows； nor from within be torn
By penetration； nor be overthrown
By any assault soever through the world…
For without void； naught can be crushed； it seems；
Nor broken； nor severed by a cut in twain；
Nor can it take the damp； or seeping cold
Or piercing fire； those old destroyers three；
But the more void within a thing； the more
Entirely it totters at their sure assault。
Thus if first bodies be； as I have taught；
Solid； without a void； they must be then
Eternal； and； if matter ne'er had been
Eternal； long ere now had all things gone
Back into nothing utterly； and all
We see around from nothing had been born…
But since I taught above that naught can be
From naught created； nor the once begotten
To naught be summoned back； these primal germs
Must have an immortality of frame。
And into these must each thing be resolved；
When comes its supreme hour； that thus there be
At hand the stuff for plenishing the world。
。 。 。 。 。 。
So primal germs have solid singleness
Nor otherwise could they have been conserved
Through aeons and infinity of time
For the replenishment of wasted worlds。
Once more； if nature had given a scope for things
To be forever broken more and more；
By now the bodies of matter would have been
So far reduced by breakings in old days
That from them nothing could； at season fixed；
Be born； and arrive its prime and top of life。
For； lo； each thing is quicker marred than made；
And so whate'er the long infinitude
Of days and all fore…passed time would now
By this have broken and ruined and dissolved；
That same could ne'er in all remaining time
Be builded up for plenishing the world。
But mark： infallibly a fixed bound
Remaineth stablished 'gainst their breaking down；
Since we behold each thing soever renewed；
And unto all； their seasons； after their kind；
Wherein they arrive the flower of their age。
Again； if bounds have not been set against
The breaking down of this corporeal world；
Yet must all bodies of whatever things
Have still endured from everlasting time
Unto this present； as not yet assailed
By shocks of peril。 But because the same
Are； to thy thinking； of a nature frail；
It ill accords that thus they could remain
（As thus they do） through everlasting time；
Vexed through the ages （as indeed they are）
By the innumerable blows of chance。
So in our programme of creation； mark
How 'tis that； though the bodies of all stuff
Are solid to the core； we yet explain
The ways whereby some things are fashioned soft…
Air； water； earth； and fiery exhalations…
And by what force they function and go on：
The fact is founded in the void of things。
But if the primal germs themselves be soft；
Reason cannot be brought to bear to show
The ways whereby may be created these
Great crags of basalt and the during iron；
For their whole nature will profoundly lack
The first foundations of a solid frame。
But powerful in old simplicity；
Abide the solid； the primeval germs；
And by their combinations more condensed；
All objects can be tightly knit and bound
And made to show unconquerable strength。
Again； since all things kind by kind obtain
Fixed bounds of growing and conserving life；
Since Nature hath inviolably decreed
What each can do； what each can never do；
Since naught is changed； but all things so abide
That ever the variegated birds reveal
The spots or stripes peculiar to their kind；
Spring after spring： thus surely all that is
Must be composed of matter immutable。
For if the primal germs in any wise
Were open to conquest and to change； 'twould be
Uncertain also what could come to birth
And what could not； and by what law to each
Its scope prescribed； its boundary stone that clings
So deep in Time。 Nor could the generations
Kind after kind so often reproduce
The nature； habits； motions； ways of life；
Of their progenitors。
And then again；
Since there is ever an ext
