“Love? What is it? The most natural painkiller what there is.”

You may become curious, though, about what happened to that painkiller should depression take hold and expose your love—whatever its object—as just one of the many intoxicants that muddled your consciousness of the human tragedy. You may also want to take a second look at whatever struck you as a person, place, or thing of “beauty,” a quality that lives only in the neurotransmitters of the beholder. (Aesthetics? What is it? A matter for those not depressed enough to care nothing about anything, that is, those who determine almost everything that is supposed to matter to us. Protest as you like, neither art nor an aesthetic view of life are distractions granted to everyone.) In depression, all that once seemed beautiful, or even startling and dreadful, is nothing to you. The image of a cloud-crossed moon is not in itself a purveyor of anything mysterious or mystical; it is only an ensemble of objects represented to us by our optical apparatus and perhaps processed as a memory.
