LANGUAGE NOTE | Document text in English ; abstract also in Chinese. 本文介紹生物倫理學與公共健康倫理學領域,並描述兩者之間的關係;文章尾聲將展望公共健康倫理學論未來既廣泛又多變的方向。本文首先簡介公共健康倫理學的本質,以及如何把其與比之更廣闊的生物倫理學作出區分,因此需要提出公共健康倫理學的定義,以助釐清公共健康倫理的重點。隨後,本文簡述公共健康倫理學文獻的一些最新進展,包括圍繞新冠病毒、大流行病、抗菌素抗藥性、「生活方式」疾病及正義等道德問題。本文同時論及就干預公共健康的「合法範圍」所提出的觀點之間於政治及形而上學的角力。其後本文探討公共健康倫理學所面臨的挑戰,包括其複雜又多元的性質。而且公共健康實踐高度政治化,其政治化的原因是因為公共健康影響整個人口及社區,而很多關於公共健康的決策由政治人物而非公共健康專家所作出。此外,公共健康倫理也因為公共健康的範圍擴展至納入非政府公共健康行動者而面臨進一步的挑戰。本文最後闡述有關公共健康的一些未來方向,包括「公共健康觀」的出現,以作為為人熟知的健康與社會問題的形而上學框架、把該領域的認知和道德基礎去殖民化以涵蓋更廣泛的知識,以及一些包括美德在内的公共健康倫理學的理論發展。筆者建議讀者把文章視為對公共健康倫理學領域的一部分介紹,並鼓勵他們閲讀本文所引用的論文,並以這些論文作為進入所涵蓋主題的大量文獻之門徑。公共健康倫理學是一個相對年輕的領域,而該領域有著巨大的成長及發掘更多新概念的潛力。 This essay begins by introducing the fields of bioethics and public health ethics and describing the relationship between them. It ends with some glimpses into the wide-ranging and discourse-changing directions of the literature on public health ethics. To open, the paper describes the field of public health ethics and how it is differentiated from the wider field of bioethics. This requires a brief description of public health to clarify the nature of public health ethics. The essay then provides a brief overview of a few recent developments in the public health ethics literature, including the moral issues raised by COVID-19 and pandemics, anti-microbial resistance, ‘lifestyle’ diseases and justice. The paper also touches on the political and metaphysical tensions in views on what counts as a ‘legitimate area’ of intervention for public health. The essay then turns to a couple of challenges in the field of public health ethics, specifically the complex and multi-disciplinary nature of the field and the fact that public health practice is a highly political area. Public health is political both in the sense that it affects entire populations or communities and in the sense that many decisions about public health are made by politicians rather than public health experts. A further challenge to public health ethics is the question of what counts as ‘public health’, as the scope has been broadened to include non-governmental public health actors. Finally, the essay describes some future directions for research in public health ethics, including ‘public health view’ becoming a metaphysical framing for familiar health and social issues and decolonising the epistemic and moral foundations of the field to include a wider set of knowledge sources and values. There are also some theoretical developments that integrate virtue into public health ethics. The reader should take this essay as a partial introduction to the field, and they are highly encouraged to read the papers that are cited here and to use those papers as a gateway into the large literature on the topics covered. Public health ethics is a relatively young field, with an enormous potential for growth and new ideas.
