"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."
