This paper draws attention to the remarkable closing words of Isaac Newton's Optice (1706) and subsequent editions of the Opticks (1718, 1721), and tries to suggest why Newton chose to conclude his book with a puzzling allusion to his own unpublished conclusions about the history of religion. Newton suggests in this concluding passage that the bounds of moral philosophy will be enlarged as natural philosophy is 'perfected'. Asking what Newton might have had in mind, the paper first considers the idea that he was foreshadowing the 'moral Newtonianism' developed later in the eighteenth century; then it considers the idea that he was perhaps pointing to developments in natural theology. Finally, the paper suggests that Newton wanted to at least signal the importance of attempting to recover the true original religion, and perhaps was hinting at his intention to publish his own extensive research on the history of the Church.

扩大道德哲学的界限：艾萨克·牛顿为什么以他的方式总结《 Opticks》？

本文提请人们注意艾萨克·牛顿（Isaac Newton）的《光学》（Optice）（1706）及其后续版本的《光学》（Opticks）（1718、1721）的非凡的结语，并试图建议牛顿为何选择对他自己尚未发表的有关该结论的结论感到困惑宗教史。牛顿在这一结论性段落中建议，随着自然哲学的“完善”，道德哲学的范围将会扩大。在问牛顿可能有什么想法时，论文首先考虑了他预示着18世纪后期发展的“道德牛顿主义”的想法。然后认为他也许是指自然神学的发展。最后，该论文表明，牛顿至少想表达试图恢复真正的原始宗教的重要性，
