Abstract

The mere means principle says it is impermissible to treat someone as merely a means to someone else’s ends. I specify this principle with two conditions: a victim is used as merely a means if the victim does not want the treatment by the agent and the agent wants the presence of the victim’s body. This principle is a specification of the doctrine of double effect which is compatible with moral intuitions and with a restricted kind of libertarianism. An extension of this mere means principle, where not only using but also considering someone as merely a means is immoral, can explain and unify other deontological principles: doing versus allowing, partiality in imperfect duties of beneficence, and the asymmetry of procreational duties. A loop trolley dilemma is often presented as a counterexample of the mere means principle, but I argue that this dilemma generates a moral illusion, comparable to perceptual illusions.
