To procreate is thus to engage in a kind of Russian roulette, but one in which the "gun" is aimed not at oneself but instead at one's offspring. You t… - David Benatar

[T]he optimist’s impatience with or condemnation of pessimism often has a smug macho tone to it (although males have no monopoly of it). There is a scorn for the perceived weakness of the pessimist who should instead ‘grin and bear it’. This view is defective for the same reason that macho views about other kinds of suffering are defective. It is an indifference to or inappropriate denial of suffering, whether one’s own or that of others. The injunction to ‘look on the bright side’ should be greeted with a large dose of both scepticism and cynicism. To insist that the bright side is always the right side is to put ideology before the evidence. Every cloud, to change metaphors, may have a silver lining, but it may very often be the cloud rather than the lining on which one should focus if one is to avoid being drenched by self-deception. Cheery optimists have a much less realistic view of themselves than do those who are depressed.

Creating new people, by having babies, is so much a part of human life that it is rarely thought even to require a justification. Indeed, most people do not even think about whether they should or should not make a baby. They just make one. In other words, procreation is usually the consequence of sex rather than the result of a decision to bring people into existence. Those who do indeed decide to have a child might do so for any number of reasons, but among these reasons cannot be the interests of the potential child. One can never have a child for that child's sake.

Further insight into the poor quality of human life can be gained from considering various traits that are often thought to be components of a good life and by noting what limited quantities of these characterize even the best human lives. For example, knowledge and understanding are widely thought to be goods, and people are often in awe of how much knowledge and understanding (some) humans have. The sad truth, however, is that, on the spectrum from no knowledge and understanding to omniscience, even the cleverest, best-educated humans are much closer to the unfortunate end of the spectrum. There are billions more things we do not know or understand than we do know and understand. If knowledge really is a good thing and we have so little of it, our lives are not going very well in this regard. Similarly, we consider longevity to be a good thing (at least if the life is above a minimum quality threshold). Yet even the longest human lives are ultimately fleeting. If we think that longevity is a good thing, then a life of a thousand years (in full vigor) would be much better than a life of eighty or ninety years (especially when the last few decades are years of decline and decrepitude). Ninety years are much closer to one year than to a thousand years. It is even more distant from two thousand or three thousand or more. If, all things being equal, longer lives are better than shorter ones, human lives do not fare well at all.
