The inconceivable idea of the sun.
You must become an ignorant man again
And see the sun again with an ignorant eye
And see it clearly in the idea of it.

In these lines Stevens presses a characteristic Modernist paradox: the most familiar object—the sun—becomes “inconceivable” once it is overlaid with habit, knowledge, and inherited meanings. To “become an ignorant man again” is not anti-intellectualism but a call to recover first-hand perception, a disciplined freshness of attention. Seeing “clearly in the idea of it” suggests that imagination and concept are not enemies of reality; they are the means by which reality is apprehended. The passage dramatizes Stevens’s recurring theme that the world is continually remade in consciousness, and that clarity requires stripping away secondhand interpretations to re-encounter the thing as if for the first time.
