Lopate on Sontag via her son

I love this Phillip Lopate essay in the current Threepenny Review (yes, I'm reading it this morning when I should be working) about Susan Sontag's Under the Sign of Saturn and melancholia, including this anecdote from her son's memoir:

"...she was almost always dueling with depression. This was clearest immediately after she woke up, when, in an effort to shake off her despondency, she would talk, about anything and at breakneck speed, as if to overwhelm her mood with meteor showers of verbiage."
