Can there be a duty to love someone? Many people do not think so. One common objection, what I call the commandability objection, says that duty requires that the action required by the duty to be commandable, but love is an emotion and emotions are not commandable. Another objection, what I call the motivation objection, says that really to love a person, one must be motivated to love the person for the person’s sake. However, to have a duty to love means that one would not be motivated to love the person for the person’s sake, but for the sake of the duty. In this paper, I examine both objections and I argue that neither undermines the idea of a duty to love. [Journal of Value Inquiry 40(1) 2006: 1-22] [pdf | html]
