Not all bad, then?

NYT article on the "Upside" of the Black Dog.

This radical idea — the scientists were suggesting that depressive disorder came with a net mental benefit — has a long intellectual history. Aristotle was there first, stating in the fourth century B.C. “that all men who have attained excellence in philosophy, in poetry, in art and in politics, even Socrates and Plato, had a melancholic habitus; indeed some suffered even from melancholic disease.” This belief was revived during the Renaissance, leading Milton to exclaim, in his poem “Il Penseroso”: “Hail divinest Melancholy/Whose saintly visage is too bright/To hit the sense of human sight.” The Romantic poets took the veneration of sadness to its logical extreme and described suffering as a prerequisite for the literary life. As Keats wrote, “Do you not see how necessary a World of Pains and troubles is to school an intelligence and make it a soul?”

Ah, yes.  Keats.  It would be Keats, wouldn't it? 


The bad news is that this deliberate thought process is slow, tiresome and prone to distraction; the prefrontal cortex soon grows exhausted and gives out. Andrews and Thomson see depression as a way of bolstering our feeble analytical skills, making it easier to pay continuous attention to a difficult dilemma. The downcast mood and activation of the VLPFC are part of a “coordinated system” that, Andrews and Thomson say, exists “for the specific purpose of effectively analyzing the complex life problem that triggered the depression.” If depression didn’t exist — if we didn’t react to stress and trauma with endless ruminations — then we would be less likely to solve our predicaments. Wisdom isn’t cheap, and we pay for it with pain.

That's a fine bit of writing right there at the end.
