On the nature of things (books 4 - 6)   

Along the Atlantic shore and wastes of sea?-
Where neither one of us approacheth nigh
Nor no barbarian ventures. And the rest
Of all those monsters slain, even if alive,
Unconquered still, what injury could they do?
None, as I guess. For so the glutted earth
Swarms even now with savage beasts, even now
Is filled with anxious terrors through the woods
And mighty mountains and the forest deeps-
Quarters 'tis ours in general to avoid.
But lest the breast be purged, what conflicts then,
What perils, must bosom, in our own despite!
O then how great and keen the cares of lust
That split the man distraught! How great the fears!
And lo, the pride, grim greed, and wantonness-
How great the slaughters in their train! and lo,
Debaucheries and every breed of sloth!
Therefore that man who subjugated these,
And from the mind expelled, by words indeed,
Not arms, O shall it not be seemly him
To dignify by ranking with the gods?-
And all the more since he was wont to give,
Concerning the immortal gods themselves,
Many pronouncements with a tongue divine,
And to unfold by his pronouncements all
The nature of the world.

ARGUMENT OF THE BOOK AND NEW
PROEM AGAINST TELEOLOGICAL
CONCEPT

And walking now
In his own footprints, I do follow through
His reasonings, and with pronouncements teach
The covenant whereby all things are framed,
How under that covenant they must abide
Nor ever prevail to abrogate the aeons'
Inexorable decrees- how (as we've found),
In class of mortal objects, o'er all else,
The mind exists of earth-born frame create
And impotent unscathed to abide
Across the mighty aeons, and how come
In sleep those idol-apparitions
That so befool intelligence when we
Do seem to view a man whom life has left.
Thus far we've gone; the order of my plan
Hath brought me now unto the point where I
Must make report how, too, the universe
Consists of mortal body, born in time,
And in what modes that congregated stuff
Established itself as earth and sky,
Ocean, and stars, and sun, and ball of moon;
And then what living creatures rose from out
The old telluric places, and what ones
Were never born at all; and in what mode
The human race began to name its things
And use the varied speech from man to man;
And in what modes hath bosomed in their breasts
That awe of gods, which halloweth in all lands
Fanes, altars, groves, lakes, idols of the gods.
Also I shall untangle by what power
The steersman Nature guides the sun's courses,
And the meanderings of the moon, lest we,
Percase, should fancy that of own free will
