The Principle of Procreative Beneficence (PPB) claims that we have a moral obligation, where choice is possible, to choose to create the best child we can. The existence of this moral obligation has been proposed by John Harris and Julian Savulescu and has proved controversial on many levels, not least that it is eugenics, asking us to produce the best children we can, not for the sake of that child's welfare, but in order to make a better society. These are strong claims that require robust justification that can be open to scrutiny and debate. This article argues that robust justifications are currently lacking in the work of Savulescu and Harris. The justifications provided for their conclusions about this obligation to have the best child possible rely heavily on Derek Parfit's Non-Identity Problem and the intuitive response this provokes in many of us. Unfortunately Harris and Savulescu do not embrace the entirety of the Non-Identity Problem and the puzzle that it presents. The Non-Identity Problem actually provides a refutation of PPB. In order to establish PPB as a credible and defendable principle, Harris and Savulescu need to find what has eluded Parfit and many others: a solution to the Non-Identity Problem and thus an overturning of the refutation it provides for PPB. While Harris and Savulescu do hint at possible but highly problematic solutions to the Non-Identity Problem, these are not developed or defended. As a result their controversial is left supported by little more than intuition.
生殖利他主义原则(PPB)宣称,在有可能做出选择的情况下,我们有道义上的责任去选择生育我们所能生育的最优孩子。约翰·哈里斯和朱利安·萨夫勒斯库提出了这一道德责任的存在,并且在许多层面上引发了争议,尤其是它被指是优生学,要求我们生育所能生育的最优孩子,不是为了那个孩子的福祉,而是为了创造一个更美好的社会。这些都是强有力的主张,需要有经得起审视和辩论的有力正当理由。本文认为,萨夫勒斯库和哈里斯的著作目前缺乏有力的正当理由。他们就生育最优孩子这一责任所得出的结论所提供的正当理由,严重依赖德里克·帕菲特的非同一性问题以及这一问题在我们许多人心中引发的直观反应。不幸的是,哈里斯和萨夫勒斯库并未接受非同一性问题的全部内容及其所呈现的谜题。非同一性问题实际上对生殖利他主义原则进行了反驳。为了将生殖利他主义原则确立为一个可信且可辩护的原则,哈里斯和萨夫勒斯库需要找到帕菲特和其他许多人都未能找到的东西:非同一性问题的解决方案,从而推翻它对生殖利他主义原则的反驳。虽然哈里斯和萨夫勒斯库确实暗示了非同一性问题可能的但极有问题的解决方案,但这些方案并未得到展开或辩护。结果,他们有争议的观点几乎仅仅是靠直觉来支撑。
