Given the central place organisms occupy in Kant’s account of living nature, it might seem unlikely that his claims about biological wholes could be relevant to current debates over the problem of biological individuality. These debates acknowledge the multiple realizability of biological individuality in vastly different forms, including parts of organisms and complex groups of organisms at various levels of the biological hierarchy, sparking much controversy in attempts to characterize a biological individual. I argue that, far from being irrelevant to (...) this controversy, Kant’s account provides a key insight for addressing the multiple realizability problem. I show how the reciprocal causality between a self-organizing whole and its parts, which Kant thinks characterizes a natural end, is not limited to organisms but is exhibited by numerous types of beings in living nature. Self-organizing wholes of various kinds, and at various biological levels, may count as biological individuals, depending on the degree to which their functionally integrated parts are represented by reflective judgement as a natural end.

In the debate over moral bioenhancement, some object that biochemical, genetic, and neurological interventions aiming at enhancing moral agency threaten the autonomy of persons, as they compromise moral deliberation and motivation. Opponents of this view argue that such interventions may actually enhance autonomy itself, thereby increasing a person's capacity for moral agency. My aim is to explore the various senses of autonomy commonly appealed to in such controversies and to expose their limitations in resolving the central disputed issues. I propose (...) that a Kantian conception of autonomy is more effective in addressing these issues, as it specifies the key features that inform an intelligible account of moral worth and moral law. A consideration of these features is typically lacking in the arguments advanced by contenders in these debates. Guided by a Kantian framework, I argue that moral bioenhancement projects directed at affecting moral autonomy are not as promising as they appear, for both metaphysical and empirical reasons.
