Each one of us was harmed by being brought into existence. That harm is not negligible, because the quality of even the best lives is very bad—and co… - David Benatar

In coming into existence, we are guaranteed to suffer harms. The nature and magnitude of those harms vary from person to person. However, it is more common than not for these harms to include formidable ones: grinding poverty (and its associated costs), chronic pain, disability, disease, trauma, shame, loneliness, unhappiness, frailty, and decrepitude. Sometimes, these mark an entire life. Other times, they begin to intrude into a life that was previously devoid of them. For example, no matter how youthfully robust one may be now, a time will come when one will become enfeebled, unless something else gets one first. Although there are some things we can do to prevent or delay some of these harms, our fate, to a considerable extent, is out of our control. We may attempt to preserve our health, but all we can do thereby is reduce, not eliminate, the risks. Therefore, we have some, but relatively little, control over whether these harms will befall us.

It is also suggested that the bad things in life are necessary in order to appreciate the good things, or at least to appreciate them fully. On this view, we can only enjoy pleasures (as much as we do) because we also experience pain. Similarly, our achievements are more satisfying if we have to work hard to attain them, and fulfilled desires mean more to us because we know that desires are not always fulfilled. There are many problems with this sort of argument. First, these sorts of claims are not always true. There is much pain that serves no useful purpose. There is no value in labor pains or in pain resulting from terminal diseases, for example. While the pain associated with kidney stones might now lead somebody to seek medical help, for most of human history, such pain served no purpose, as there was absolutely nothing anybody could do about kidney stones. Moreover, there are at least some pleasures we can enjoy without having to experience pain. Pleasant tastes, for example, do not require any experience of pain or unpleasantness. Similarly, many achievements can be satisfying even if they involve less or no striving. There may be a special satisfaction in the ease of attainment. There may be some individual variation. Perhaps some people are more capable of enjoying pleasure without having to experience pain and more capable of taking satisfaction in achievements that come with ease. Second, insofar as the good things in life do require a contrast in order to be fully appreciated, it is not clear that this appreciation requires as much bad as there is. We do not, for example, require millions of people suffering from chronic pain, infectious diseases, advancing paralysis, and tumors in order to appreciate the good things in life. We could enjoy our achievements without having to work quite so hard to attain them.

Our lives contain so much more bad than good in part because of a series of empirical differences between bad things and good things. For example, the most intense pleasures are short-lived, whereas the worst pains can be much more enduring. Orgasms, for example, pass quickly. Gastronomic pleasures last a bit longer, but even if the pleasure of good food is protracted, it lasts no more than a few hours. Severe pains can endure for days, months, and years. Indeed, pleasures in general—not just the most sublime of them—tend to be shorter-lived than pains. Chronic pain is rampant, but there is no such thing as chronic pleasure. There are people who have an enduring sense of contentment or satisfaction, but that is not the same as chronic pleasure. Moreover, discontent and dissatisfaction can be as enduring as contentment and satisfaction; this means that the positive states are not advantaged in this realm. Indeed, the positive states are less stable because it is much easier for things to go wrong than to go right. The worst pains are also worse than the best pleasures are good. Those who deny this should consider whether they would accept an hour of the most delightful pleasures in exchange for an hour of the worst tortures. Arthur Schopenhauer makes a similar point when he asks us to “compare the respective feelings of two animals, one of which is engaged in eating the other.” The animal being eaten suffers and loses vastly more than the animal that is eating gains from this one meal. Consider too the temporal dimensions of injury or illness and recovery. One can be injured in seconds: One is hit by a bullet or projectile, or is knocked over or falls, or suffers a stroke or heart attack. In these and other ways, one can instantly lose one’s sight or hearing or the use of a limb or years of learning. The path to recovery is slow. In many cases, full recovery is never attained. Injury comes in an instant, but the resultant suffering can last a lifetime. Even lesser injuries and illnesses are typically incurred much more quickly than one recovers from them. For example, the common cold strikes quickly and is defeated much more slowly by one’s immune system. The symptoms manifest with increasing intensity within hours, but they take at least days, if not weeks, to disappear entirely.
