Philosophical Anthropology, Ethics and Human Enhancement
Jason Eberl, Ph.D., Semler Endowed Chair for Medical Ethics and Professor of Philosophy, Marian University College of Osteopathic Medicine
I approach the subject of human enhancement—whether by genetic, pharmacological, or technological means—from the perspective of Thomistic/Aristotelian philosophical anthropology, natural law theory, and virtue ethics. Far from advocating a restricted or monolithic conception of “human nature” from this perspective, I outline a set of broadly-construed, fundamental features of the nature of human persons that coheres with a variety of historical and contemporary philosophical viewpoints. These features include self-conscious awareness, capacity for intellective thought, volitional autonomy, desire for pleasurable experiences, and the necessity of healthy biological functioning. On this basis, I contend that there may be legitimate forms of human enhancement for specific purposes related to the physical, cognitive, and emotive dimensions of human existence. However, wider philosophical considerations call into question whether societal attitudes towards enhancement and the differences that may emerge between those who are enhanced versus the unenhanced may raise insurmountable questions of justice, as well as a loss of virtues associated with what Alasdair MacIntyre refers to as our “acknowledged dependency.” This presentation will navigate towards conclusions differentiating principled from practical objections to specific forms of, and means towards achieving, enhancement of certain human capacities. While critical of some forms of human enhancement, I nevertheless argue that other forms of enhancement are, in principle, morally permissible—and for which any practical concerns may be surmountable—insofar as they positively support human flourishing according to our nature as living, sentient, social, and rational animals.
