A reader responds to the philosophy of truth in Emily Dickinson's poetry:

[It] seems like the metaphysical equivalent of what stargazers call averted vision. If you are trying to observe a dim object in the night sky, it is better to look a little to one side of it rather than straight on, because the rod cells toward the periphery of the retina gather more light in those conditions than the cone cells at the center. The trade-off is that you won't see color or fine detail, but at least you will know that something is there.
