A key aspect of transhumanist thought involves the modification or augmentation of human physical and mental capabilities—a form of intervention often encapsulated under the term "enhancement." This article provides an overview of the concept of enhancement, focusing on six major areas in which usages of the term become slippery and controversial: normal or species-typical functioning, therapeutics or healing, natural functioning, human nature, authenticity, and the ambiguity between "more" and "better." I argue that we need to be aware of the tendency (...) to embed the concept of enhancement within stark binary oppositions that seem perfectly reasonable at first glance, but that in fact yield little more than conceptual muddles if they are not handled carefully.

Over the coming century, the accelerating advance of bioenhancement technologies, robotics, and artificial intelligence (AI) may significantly broaden the qualitative range of sentient and intelligent beings. This article proposes a taxonomy of such beings, ranging from modified animals to bioenhanced humans to advanced forms of robots and AI. It divides these diverse beings into three moral and legal categories—animals, persons, and presumed persons—describing the moral attributes and legal rights of each category. In so doing, the article sets forth a framework (...) for extending the concept of personhood well beyond its current boundaries, assigning moral standing to a variety of biological and nonbiological beings. The author concludes that six of the eight subgroups of such beings deserve to be treated as persons or as if they were persons, with full consideration for their presumed interests, rights, obligations, and capabilities for ethically significant agency and patiency.
