Strength

One of my favourite bits of the Prelude [1850; XII:269-71]:

Feeling comes in aid
Of feeling, and diversity of strength
Attends us, if but once we have been strong.

Rather like Keats's beauty-truth equivalence (with which it has, I think, something deep in common) it doesn't seem to impair the effectiveness of this as poetry that it is, patently, untrue. That in itself is a puzzling thing.
