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
