Abstract

As science and technology advance, human civilization is confronting existential crises such as the depletion of resources, climate change, and the use of weapons of mass destruction. As a result, many bioethicists are proactively exploring the utilization of biomedical technology to improve human morality and overcome ethical challenges associated with scientific progress. Moral bioenhancement can be categorized into two types: moral-motivational enhancement and moral-cognitive enhancement. However, every proposed method of moral bioenhancement has raised both technical and ethical concerns. This article sequentially reviews the two categories of technical means for moral bioenhancement, illustrate their shortcomings, and briefly analyze the potential direction of moral enhancement with an eye to the current progress in artificial intelligence.
