Rather, he claims, the nonexistence of a suffering being is a positive good. From this assertion he derives the conclusion that it would be better for any being never to have existed, unless that being never experiences any suffering in its life. </p> <p> I argue that that central claim is mistaken; that the nonexistence of a suffering being is the absence of bad, not a positive good. First, we must address an ambiguity in the calculation. What constitutes a nonexistent person that we should count? </p> <h3>* Counting possible persons from this world only</h3> <p> Suppose we interpret "nonexistent possible persons" as including only those who are possible in the world as it is. Only a minute fraction of those possible people exist. If each one that doesn't exist is a positive good, comparable in size to the good or bad experienced by an existing person, it follows that the total good is measured, to a close approximation, by the number of possible people — which, with this interpretation, can be changed by our own actions. We could contribute enormous good to the world by increasing the range of nonexisters (nonexistent possible persons), assuming nearly all of them would suffer if they existed. </p> <p> If we could double the range of possible people without any other change in the world, there would be (slightly more than) twice as many nonexisters. If each one contributes the same good, that approximately doubles the total good. The effects of whatever we might do to alter the circumstances of <em>existing</em> people would be negligible by comparison. </p> <p> How might we double the range? One way is to create a new allele, not found in nature, as an alternative to some existing gene found in all humans. Suppose this new allele would not be fatal but would cause a lot of suffering. Of course, to put that gene into anyone would be cruel and wrong , but for this purpose we do not entertain the idea of <em>using</em> it. The goal is achieved by its mere existence, which would (more than) double the number of nonexistent possible humans, and thus double the good of their nonexistence. There could hardly be an easier way to add so much good to the world, so we should focus our efforts on this goal — or so we would conclude from Benatar's matrix of values. </p> <p> This absurd conclusion shows it is a mistake to assign "good" to that slot in the value matrix. We must put there "absence of bad" — in effect, zero. Whatever might have happened to a nonexistent potential being contributes zero to the total good in the world and to the total bad in the world. Thus, the number of nonexisters has no effect on any judgments about actual good or bad in this world. </p> <p> Compared with pain felt by a being that exists, zero is a step up. I suggest that is sufficient to justify the conclusion that one ought not to create a sentient being whose life would be great suffering. </p> <h3>* Counting possible persons from any world</h3> <p> It is not clear that "nonexistent persons" must be limited to those that could exist in the world as it is. Another plausible interpretation includes all persons that might exist even in worlds different from our own. </p> <p> With that interpretation, the set of possible persons is independent of anything we do; our actions can only transfer some of the possible persons from nonexistent to existent or vice versa. It follows that attributing a nonzero value X to the nonexistence of a possible person is equivalent to counting the value -X for the existence of the same possible person. These two value matrixes are equivalent as regards preferences between scenarios, because they differ uniformly for all scenarios by the constant X. </p> <p> Therefore, we are entitled remove the paradox of a nonzero value X for a nonexistent possible person by subtracting X from both sides. </p> <h3>* Conclusion about the good of a nonexistent sufferer</h3> <p> If we count only the persons that are possible in the actual world, the paradoxical nonzero value for a nonexistent sufferer is wrong; if we count all the persons possible in any world, the paradoxical nonzero value can be removed by a reformulation that makes no real difference. Either way, we can use a value matrix that avoids the paradox. </p> <h3>* Worth of starting or continuing life</h3> <p> Benatar also discusses the difference between the question of whether a person's life was worth starting (for that person), and whether it is worth continuing at time t (again, for that person). They are different, but how much? I suggest that they may have quite different answers for an adult, but there is little difference between them for someone born recently. In other words, I propose that this equation holds, in the absence of some grave problem in X's birth, </p> <pre> lim Is X's worth continuing = Was X's life worth starting t -> start of X's existence </pre> <p> which says that the value of X's existence as a function of time is continuous at the time of X's birth. </p> <p> Copyright 2015 Richard Stallman Released under Creative Commons Attribution Noderivatives 3.0 </p> </body> </html>
