Analysis of In a Lecture Room

Away, haunt thou me not,
Thou vain Philosophy!
Little hast thou bestead,
Save to perplex the head,
And leave the spirit dead.
Unto thy broken cisterns wherefore go,
While from the secret treasure-depths below,
Fed by the skyey shower,
And clouds that sink and rest on hilltops high,
Wisdom at once, and Power,
Are welling, bubbling forth, unseen, incessantly?
Why labor at the dull mechanic oar,
When the fresh breeze is blowing,
And the strong current flowing,
Right onward to the Eternal Shore?
