A person enters the moral realm when she affirms that other persons matter in the same way that she does. This, of course, is just the beginning, for she must then determine what follows from this affirmation. One way in which we treat other persons as mattering is by respecting them. And one way in which we respect persons is by respecting their wishes, desires, decisions, choices, ends, and goals. I will call all of these things ‘aims.’ Sometimes we respect another person's aims simply by refraining from doing certain things, such as treating her in ways that thwart her aims, or interfering with her attempt to pursue them. Other times we respect a person's aims by taking positive action to help her pursue them.

But how exactly does respect for persons translate into respect for their aims? And which aims merit respect? One answer comes from Kant.

Le philosophe mit le pied sur la première marche du futurotron. C'était la première fois qu'il utilisait cet appareil pour ses recherches. Bien qu'il vienne seulement d'être mis au point et qu'il ne soit encore qu'à l'état de prototype, ce futurotron pouvait décidément rendre de grands services. De nombreux chercheurs de différentes disciplines l'avaient d'ailleurs déjà utilisé de manière très fructueuse.
