How we are screwing stuff up, and how we’re trying to fix it

2. But nature is a stranger yet;
The ones that cite her most
Have never passed her haunted house,
Nor simplified her ghost.
To pity those that know her not
Is helped by the regret
That those who know her, know her less
The nearer that they get.
-Emily Dickinson
