No More Learning

Nor do I
Fail to perceive how strange and marvellous
This fact must strike the intellect of man,--
          of the sky and earth
That is to be,--and with what toil of words
'Tis mine to prove the same; as happens oft
When once ye offer to man's listening ears
Something before unheard of, but may not
Subject it to the view of eyes for him
Nor put it into hand--the sight and touch,
Whereby the opened highways of belief
Lead most directly into human breast
And regions of intelligence.
