When I heard the learn'd astronomer,
When the proofs, the figures, were ranged in columns before me,
When I was shown the charts and diagrams, to add, divide, and measure them,
When I sitting heard the astronomer where he lectured with much
applause in the lecture-room,
How soon unaccountable I became tired and sick,
Till rising and gliding out I wander'd off by myself,
In the mystical moist night-air, and from time to time,
Look'd up in perfect silence at the stars.
The narrator makes a deeper connection with space and the universe by simply looking up at the stars instead of overanalyzing it through math and charts. The use of “perfect silence” and “look’d up” is also a contrast with how at the beginning of the poem, all the narrator was doing was listening.
