Vulnerable Persons

Abstract

Looking at the measurement of moral capacity is an opportunity to clarify some aspects of moral capacity. The measurement to be focused on is the evaluation of moral capacity for the purposes of individual and population comparisons. I will present a positive argument that the measurement of moral capacity is possible. This possibility rests upon gaining clarity on the nature of the moral field that in turn requires a corresponding view of human nature. Having examined these issues, I go on to discuss moral capacity like any other human capacity. Throughout this discussion a negative argument is woven to the effect that measurement of moral capacity is not currently feasible. Furthermore, vigilance is recommended because premature efforts to measure and compare moral capacity are likely. The chapter concludes by examining the implications of measuring moral capacity for a principle of charity.
