Dignity, being and becoming in research ethics

Since the end of World War II, most guidelines governing human research seem to have relied on the principle of respect for autonomy as a key, though not sole, criterion in assessing the moral validity of research involving human participants.1 One explanation for this apparent reliance on respect for autonomy may be that respect for autonomy, made effective through the practice of obtaining informed consent, functions as a useful proxy when dealing with competent adults for the more complex principle of respect for human dignity that underpins much of the moral discourse in this area. If this explanation holds, then assessment of the moral licitness of research involving human individuals whose autonomy is limited in some way requires a deeper analysis of the ‘thicker’ concepts of human dignity, since we cannot rely on respect for autonomy to do the work of respect for human dignity where autonomy (understood as a capacity to consent based on adequate information) is not present, is limited or is compromised
