Bioethical issues are practically urgent, politically divisive, and call for resolutions. They often involve questions that are perplexing, deep, and profound. To deal with them adequately requires philosophical tools and imagination. The Lanson Lectures in Bioethics were founded upon the belief that philosophical elucidation can clarify the nature of these difficult issues, and can lead to their resolution. The present volume collects the first five lectures delivered by five preeminent moral philosophers between 2016 and 2022. In the inaugural lecture, Jonathan Glover draws a distinction between two conceptions of dignity, and brings it to bear on the issues of assisted suicide, embryo research, and genetic choices. F. M. Kamm argues that doctors are morally permitted to intentionally cause death, or assist in its being intentionally caused, when either death is imminent anyway and intentionally causing it can alone stop the pain, or ifthe patient has already decided—not unreasonably—that death is his least bad option. Are smokers who contract lung cancer entitled to state-supported healthcare? T. M. Scanlon argues that the reasons that individuals have for wanting to have the opportunity to engage in activities involving risks need to be compared with the costs society has to bear to provide healthcare for those who suffer illness or injury as a result of these activities. Rejecting Strawson’s view that a psychiatrist can only “treat” an insane patient, Victor Tadros argues that it is often right to reason with (nonresponsible) mentally ill persons because a psychiatrist needs to see things from their perspectives, and that we should communicate to nonresponsible agents that their wrongdoing is a problem for them and for their victims. Peter Singer proposes solutions to the following questions: How to distribute scarce medical resources and vaccines ethically? Whether to relax the standard for volunteers willing to participate in vaccines research? How to compare the trade-off between saving lives and saving the economy regarding lockdowns? How to prevent pandemics in future? Each lecture is followed by a critical commentary by a moral philosophers or physician in Asia. Each commentary (except the inaugural lecture) is followed by a rejoinder.
