On the nature of things (books 4 - 6)   

Succumbed, whilst each man sought unto himself
Dominion and supremacy. So next
Some wiser heads instructed men to found
The magisterial office, and did frame
Codes that they might consent to follow laws.
For humankind, o'er wearied with a life
Fostered by force, was ailing from its feuds;
And so the sooner of its own free will
Yielded to laws and strictest codes. For since
Each hand made ready in its wrath to take
A vengeance fiercer than by man's fair laws
Is now conceded, men on this account
Loathed the old life fostered by force. 'Tis thence
That fear of punishments defiles each prize
Of wicked days; for force and fraud ensnare
Each man around, and in the main recoil
On him from whence they sprung. Not easy 'tis
For one who violates by ugly deeds
The bonds of common peace to pass a life
Composed and tranquil. For albeit he 'scape
The race of gods and men, he yet must dread
'Twill not be hid forever- since, indeed,
So many, oft babbling on amid their dreams
Or raving in sickness, have betrayed themselves
(As stories tell) and published at last
Old secrets and the sins.
But Nature 'twas
Urged men to utter various sounds of tongue
And need and use did mould the names of things,
About in same wise as the lack-speech years
Compel young children unto gesturings,
Making them point with finger here and there
At what's before them. For each creature feels
By instinct to what use to put his powers.
Ere yet the bull-calf's scarce begotten horns
Project above his brows, with them he 'gins
Enraged to butt and savagely to thrust.
But whelps of panthers and the lion's cubs
With claws and paws and bites are at the fray
Already, when their teeth and claws be scarce
As yet engendered. So again, we see
All breeds of winged creatures trust to wings
And from their fledgling pinions seek to get
A fluttering assistance. Thus, to think
That in those days some man apportioned round
To things their names, and that from him men learned
Their first nomenclature, is foolery.
For why could he mark everything by words
And utter the various sounds of tongue, what time
The rest may be supposed powerless
To do the same? And, if the rest had not
Already one with other used words,
Whence was implanted in the teacher, then,
Fore-knowledge of their use, and whence was given
To him alone primordial faculty
To know and see in mind what 'twas he willed?
Besides, one only man could scarce subdue
An overmastered multitude to choose
To get by heart his names of things. A task
Not easy 'tis in any wise to teach
And to persuade the deaf concerning what
'Tis needful for to do. For ne'er would they
Allow, nor ne'er in anywise endure
Perpetual vain dingdong in their ears
