我讨厌大多数哲学，但我读了帕菲特（Parfit）那本硬核的《Reasons and Persons》（理与人），真心觉得很赞。你有没有想过传送机可以作为反驳灵魂存在的论据？帕菲特就是这么认为的。而且，他的文笔完全是为了让人看得懂而优化过的——没有任何花里胡哨的废话。……
I hate most philosophy, but I read Parfit's technical Reasons and Persons and genuinely enjoyed it. Did you ever think teleporters could be the basis for an argument against souls? Parfit thought so. Plus, his writing is optimized for being understandable -- no flowery bullshit.…
……任何持有这种立场的人都必须承认自己有可能是错的，事实上这种技术确实可行且能按预期工作。德里克·帕菲特在《Reasons and Persons》中论证的人格同一性（personal identity）理论在这里很适用。我认为不要把死亡视作必然是非常重要的，因为如果人们对战胜死亡不抱希望，那我们战胜它的可能性就更小了……
…anyone who takes such a position has to allow that there's some possibility that they're wrong, and in fact such tech is possible and would work as intended. The theories of personal identity argued in Reasons and Persons by Derek Parfit are relevant here. I think it's important that we don't accept death as inevitable, because if people don't hold out hope of conquering death, then it's less likely that we'll conquer…
……我认为不需要太多专业的哲学背景知识）但写得极其出色，且与伦理学问题高度相关，尽管它更多探讨的是人格同一性问题：德里克·帕菲特的《Reasons and persons》。他最近还写了一部两卷本的伦理学大作，我还没读过。
…I don't think much expert philosophical knowledge is needed) but extraordinarily good and highly relevant to questions of ethics, though it's more about questions of personal identity: Derek Parfit's "Reasons and persons". He's more recently written a large two-volume work on ethics, which I haven't read.
德里克·帕菲特的《Reasons and Persons》。我和《自私的基因》（The Selfish Gene）差不多同时读的，带给我的震撼很相似。这是少数几本至今仍让我回味思考的哲学书之一。
Reasons and Persons by Derek Parfit I read this about the same time I read the Selfish Gene, had a similar effect. It's one of the few philosophy books that I still think about today.
……这些灰色地带的话题，以至于我们忘记了在基本道德原则上达成共识的空间有多么巨大。道德哲学里确实存在伟大的问题。我记得第一次读德里克·帕菲特的《Reasons and Persons》并思考“令人厌恶的结论”（The Repugnant Conclusion）时，真是大开眼界。对于制定宏观政策，或面临人道主义危机与人口伦理现实问题的人来说，这绝对有用。……
…these gray zone topics, that we forget just how huge the space of basically agreed moral principles is. There certainly are great moral philosophy problems. I remember when I first read Derek Parfit's Reasons and Persons and thought about "The Repugnant Conclusion" it was eye opening. It would definitely be useful for people choosing large-scale policies or facing real problems of humanitarian crisis or population ethics.…
试试德里克·帕菲特吧。他的书《Reasons and Persons》通过清晰的思想实验探讨了一些引人入胜的问题（人格同一性），确实达到了本文所说的那种清晰度。
