Life is Habit-Forming

It is true that when a pessimist's life is threatened he behaves like other men; his impulse to preserve life is stronger than his judgment that life is not worth preserving. But how does this prove that the judgment was insincere or even erroneous? A man's judgment that whisky is bad for him is not invalidated by the fact that when the bottle is at hand he finds desire stronger than reason and succumbs. Having once tasted life, we are subjected to the impulse of self-preservation. Life, in other words, is as habit-forming as cocaine. What then? If I still held creation to be "a great injustice" I should hold that this impulse to retain life aggravates the injustice. If it is bad to be forced to drink the potion, how does it mend matters that the potion turns out to be an addiction drug? Pessimism cannot be answered so. Thinking as I then thought about the universe, I was reasonable in condemning it. At the same time I now see that my view was closely connected with a certain lopsidedness of temperament. I had always been more violent in my negative than in my positive demands. Thus, in personal relations, I could forgive much neglect more easily than the least degree of what I regarded as interference. At table I could forgive much insipidity in my food more easily than the least suspicion of what seemed to me excessive or inappropriate seasoning. In the course of life I could put up with any amount of monotony far more patiently than even the smallest disturbance, bother, bustle, or what the Scotch call kurfuffle. Never at any age did I clamor to be amused; always and at all ages (where I dared) I hotly demanded not be be interrupted. The pessimism, or cowardice, which would prefer nonexistence itself to even the mildest unhappiness was thus merely the generalization of all these pusillanimous perferences. And it remains true that I have almost all my life, been quite unable to feel that horror of nonentity, of annihilation, which, say, Dr. Johnson felt so strongly. I felt it for the first time only in 1947. But that was after I had long been reconverted and thus begun to know what life really is and what would have been lost by missing it.
