To teach the ethics of science to science majors, I follow several teachers in the literature who recommend “persona” writing, or the student construction of dialogues between ethical thinkers of interest. To engage science majors in particular, and especially those new to academic philosophy, I recommend constructing persona dialogues from Henri Poincaré’s essay, “Ethics and Science” (1963/1913), and the non-theological third chapter of Pope Francis’s (2015) encyclical on the environment, Laudato si. This pairing of interlocutors offers two advantages. The first is that science students are likely to recognize both names, since Poincaré appears in undergraduate mathematics and physics textbooks, and because Francis is an environmentalist celebrity. Hence students (in my experience) show more interest in these figures than in other philosophers. The second advantage is that the third chapter of Laudato si reads like an implicit rebuttal of Poincaré’s essay in many respects, and so contriving a dialogue between those authors both facilitates classroom discussion, and deserves attention from professional ethicists in its own right. In this paper, I present my own contrived dialogue between Francis and Poincaré, not for assigning to students as a reading, but as a template for an effective assignment product, and as a crib sheet for educators to preview the richly antiparallel themes between the two works.

为了向科学专业教授科学伦理，我跟随文学中的几位老师推荐“角色”写作，或者学生在感兴趣的伦理思想家之间建立对话。为了特别吸引科学专业的学生，​​尤其是那些刚接触学术哲学的人，我建议从 Henri Poincaré 的文章“伦理与科学”（1963/1913）和教皇弗朗西斯（2015）通谕的非神学第三章中构建人物对话。关于环境，劳达托西. 这种对话者配对提供了两个优点。首先是理科学生可能会认出这两个名字，因为庞加莱出现在本科数学和物理教科书中，而且弗朗西斯是一位环保主义者。因此，学生（根据我的经验）对这些数字比对其他哲学家表现出更多的兴趣。第二个优点是劳达托斯第三章在许多方面读起来像是对庞加莱论文的含蓄反驳，因此在这些作者之间设计对话既有助于课堂讨论，也值得专业伦理学家关注。在这篇论文中，我展示了我自己的弗朗西斯和庞加莱之间的人为对话，不是为了分配给学生作为阅读，而是作为有效作业产品的模板，以及作为教育工作者预览两者之间丰富的反平行主题的婴儿床单作品。
