The speaker is bothered by old papers, though the poem never says what they contain. Instead it gives a comparison: they feel like a high country where everyone is peaceable but somehow set against us. That's an unsettling image. Nothing is openly hostile, yet the place is still unwelcoming, and the "us" suggests the speaker feels outnumbered by whatever the papers represent, perhaps the past, old records, or earlier versions of themselves. That is a guess from the imagery, not something the poem states.
The ending turns the mood around. The speaker says they "draw things as they are," which suggests they choose honesty over comfort, and they are "glad" that their mind is troubled. The unease becomes proof of attention rather than something to escape. The title, "The enemy of the good," may hint at this: settling for something tidy or pleasant could be the real danger. The mood is quiet, wary, and stubbornly clear-eyed, with a small note of acceptance at the close.
