When things wax old with eld and foul decay；
Or when salt seas eat under beetling crags。
Thus Nature ever by unseen bodies works。
THE VOID
But yet creation's neither crammed nor blocked
About by body： there's in things a void…
Which to have known will serve thee many a turn；
Nor will not leave thee wandering in doubt；
Forever searching in the sum of all；
And losing faith in these pronouncements mine。
There's place intangible； a void and room。
For were it not； things could in nowise move；
Since body's property to block and check
Would work on all and at an times the same。
Thus naught could evermore push forth and go；
Since naught elsewhere would yield a starting place。
But now through oceans； lands； and heights of heaven；
By divers causes and in divers modes；
Before our eyes we mark how much may move；
Which； finding not a void； would fail deprived
Of stir and motion； nay； would then have been
Nowise begot at all； since matter； then；
Had staid at rest； its parts together crammed。
Then too； however solid objects seem；
They yet are formed of matter mixed with void：
In rocks and caves the watery moisture seeps；
And beady drops stand out like plenteous tears；
And food finds way through every frame that lives；
The trees increase and yield the season's fruit
Because their food throughout the whole is poured；
Even from the deepest roots； through trunks and boughs；
And voices pass the solid walls and fly
Reverberant through shut doorways of a house；
And stiffening frost seeps inward to our bones。
Which but for voids for bodies to go through
'Tis clear could happen in nowise at all。
Again； why see we among objects some
Of heavier weight； but of no bulkier size？
Indeed； if in a ball of wool there be
As much of body as in lump of lead；
The two should weigh alike； since body tends
To load things downward； while the void abides；
By contrary nature； the imponderable。
Therefore； an object just as large but lighter
Declares infallibly its more of void；
Even as the heavier more of matter shows；
And how much less of vacant room inside。
That which we're seeking with sagacious quest
Exists； infallibly； commixed with things…
The void； the invisible inane。
Right here
I am compelled a question to expound；
Forestalling something certain folk suppose；
Lest it avail to lead thee off from truth：
Waters （they say） before the shining breed
Of the swift scaly creatures somehow give；
And straightway open sudden liquid paths；
Because the fishes leave behind them room
To which at once the yielding billows stream。
Thus things among themselves can yet be moved；
And change their place； however full the Sum…
Received opinion； wholly false forsooth。
For where can scaly creatures forward dart；
Save where the waters give them room？ Again；
Where can the billows yield a way； so long
As ever the fish are powerless to go？
Thus either all bodies of motion are deprived；
Or things contain admixture of a void
Where each thing gets its start in moving on。
Lastly； where after impact two broad bodies
Suddenly spring apart； the air must crowd
The whole new void between those bodies formed；
But air； however it stream with hastening gusts；
Can yet not fill the gap at once… for first
It makes for one place； ere diffused through all。
And then； if haply any think this comes；
When bodies spring apart； because the air
Somehow condenses； wander they from truth：
For then a void is formed； where none before；
And； too； a void is filled which was before。
Nor can air be condensed in such a wise；
Nor； granting it could； without a void； I hold；
It still could not contract upon itself
And draw its parts together into one。
Wherefore； despite demur and counter…speech；
Confess thou must there is a void in things。
And still I might by many an argument
Here scrape together credence for my words。
But for the keen eye these mere footprints serve；
Whereby thou mayest know the rest thyself。
As dogs full oft with noses on the ground；
Find out the silent lairs； though hid in brush；
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 pri
