Many people today are infatuated with the biological determinants of things. They find compelling the idea that moods, tastes, preferences, and behaviors can be explained by genes, or by natural selection, or by brain amines (even though these explanations are almost always circular: if we do x, it must be because we have been selected to do x). People like to be able to say, I’m just an organism, and my depression is just a chemical thing, so, of the three ways of considering my condition, I choose the biological. People do say this. The question to ask them is, Who is the “I” that is making this choice? Is that your biology talking, too?

The decision to handle mental conditions biologically is as moral a decision as any other. It is a time-honored one, too. Human beings have always tried to cure psychological disorders through the body. In the Hippocratic tradition, melancholics were advised to drink white wine, in order to counteract the black bile. (This remains an option.) Some people feel an instinctive aversion to treating psychological states with pills, but no one would think it inappropriate to advise a depressed or anxious person to try exercise or meditation.

The recommendation from people who have written about their own depression is, overwhelmingly, Take the meds! …

… What if your sadness was grief, though? And what if there were a pill that relieved you of the physical pain of bereavement—sleeplessness, weeping, loss of appetite—without diluting your love for or memory of the dead?
