New Critical Analysis Step One: Data Gathering
Find the patterns of ideas in tension, paying attention to literary uses of language like simile, metaphor, ambiguity, irony, paradox, etc. We are looking for a theme they construct which gives the poem "organic unity" and enables it to communicate (in content and form) some important wisdom about the human condition. Because it is a poem, notice where those literary uses of language are located in the lines and stanzas (breaks added for your convenience) and where they are located in the rhyme scheme.
Farewell! thou art too dear for my possessing,
And like enough thou know'st thy estimate:
The charter of thy worth gives thee releasing;
My bonds in thee are all determinate.
For how do I hold thee but by thy granting?
And for that riches where is my deserving?
The cause of this fair gift in me is wanting,
And so my patent back again is swerving.
Thyself thou gavest, thy own worth then not knowing,
Or me, to whom thou gavest it, else mistaking;
So thy great gift, upon misprision growing,
Comes home again, on better judgment making.
Thus have I had thee, as a dream doth flatter,
In sleep a king, but waking no such matter.
