--since in things
He's heretofore seen naught of true. Thou'lt find
That from the senses first hath been create
Concept of truth, nor can the senses be
Rebutted. For criterion must be found
Worthy of greater trust, which shall defeat
Through own authority the false by true;
What, then, than these our senses must there be
Worthy a greater trust? Shall reason, sprung
From some false sense, prevail to contradict
Those senses, sprung as reason wholly is
From out the senses? --For lest these be true,
All reason also then is falsified.
Or shall the ears have power to blame the eyes,
Or yet the touch the ears? Again, shall taste
Accuse this touch or shall the nose confute
Or eyes defeat it? Methinks not so it is:
For unto each has been divided off
Its function quite apart, its power to each;
And thus we're still constrained to perceive
The soft, the cold, the hot apart, apart
All divers hues and whatso things there be
Conjoined with hues. Likewise the tasting tongue
Has its own power apart, and smells apart
And sounds apart are known. And thus it is
That no one sense can e'er convict another.
Nor shall one sense have power to blame itself,
Because it always must be deemed the same,
Worthy of equal trust. And therefore what
At any time unto these senses showed,
The same is true. And if the reason be
Unable to unravel us the cause
Why objects, which at hand were square, afar
Seemed rounded, yet it more availeth us,
Lacking the reason, to pretend a cause
For each configuration, than to let
From out our hands escape the obvious things
And injure primal faith in sense, and wreck
All those foundations upon which do rest
Our life and safety. For not only reason
Would topple down; but even our very life
Would straightaway collapse, unless we dared
To trust our senses and to keep away
From headlong heights and places to be shunned
Of a like peril, and to seek with speed
Their opposites! Again, as in a building,
If the first plumb-line be askew, and if
The square deceiving swerve from lines exact,
And if the level waver but the least
In any part, the whole construction then
Must turn out faulty--shelving and askew,
Leaning to back and front, incongruous,
That now some portions seem about to fall,
And falls the whole ere long--betrayed indeed
By first deceiving estimates: so too
Thy calculations in affairs of life
Must be askew and false, if sprung for thee
From senses false.
So all that troop of words
Marshalled against the senses is quite vain.

And now remains to demonstrate with ease
How other senses each their things perceive.

Firstly, a sound and every voice is heard,
When, getting into ears, they strike the sense
With their own body. For confess we must
Even voice and sound to be corporeal,
Because they're able on the sense to strike.
Besides voice often scrapes against the throat,
And screams in going out do make more rough
The wind-pipe--naturally enough, methinks,
When, through the narrow exit rising up
In larger throng, these primal germs of voice
Have thus begun to issue forth. In sooth,
Also the door of the mouth is scraped against
[By air blown outward] from distended [cheeks].

And thus no doubt there is, that voice and words
Consist of elements corporeal,
With power to pain. Nor art thou unaware
Likewise how much of body's ta'en away,
How much from very thews and powers of men
May be withdrawn by steady talk, prolonged
Even from the rising splendour of the morn
To shadows of black evening,--above all
If 't be outpoured with most exceeding shouts.
Therefore the voice must be corporeal,
Since the long talker loses from his frame
A part.

Moreover, roughness in the sound
Comes from the roughness in the primal germs,
As a smooth sound from smooth ones is create;
Nor have these elements a form the same
When the trump rumbles with a hollow roar,
As when barbaric Berecynthian pipe
Buzzes with raucous boomings, or when swans
By night from icy shores of Helicon
With wailing voices raise their liquid dirge.

Thus, when from deep within our frame we force
These voices, and at mouth expel them forth,
The mobile tongue, artificer of words,
Makes them articulate, and too the lips
By their formations share in shaping them.
Hence when the space is short from starting-point
To where that voice arrives, the very words
Must too be plainly heard, distinctly marked.
For then the voice conserves its own formation,
Conserves its shape. But if the space between
Be longer than is fit, the words must be
Through the much air confounded, and the voice
Disordered in its flight across the winds--
And so it haps, that thou canst sound perceive,
Yet not determine what the words may mean;
To such degree confounded and encumbered
The voice approaches us. Again, one word,
Sent from the crier's mouth, may rouse all ears
Among the populace. And thus one voice
Scatters asunder into many voices,
Since it divides itself for separate ears,
Imprinting form of word and a clear tone.
