The poem must resist intelligence
Almost successfully. Illustration:
A brune figure in winter evening resists
Identity. The thing he carries resists
The most neccessitous sense. Accept them, then,
As secondary (parts not quite percieved
Of the obvious whole, uncertain particles
Of the certain solid, the primary free from doubt
Things floating like the first hundred flakes of snow
Out of a storm we must endure all night,
Out of a storm of all secondary things),
A horror of thoughts that suddenly are real.
We must endure our thoughts all night, until
The bright obvious stands motionless in cold.
- Wallace Stevens
The sonnett and the last two lines which ring true and achingly clear: sometimes you can't deny the power of structure to carry forth meaning (be it in poem, or architecture).
