In Kantian philosophy, morality demands that individuals be treated as deserving significant and equal respect. People should be seen as ends of moral behaviour, and not just as means to independently desirable outcomes. Morality is grounded on the categorical imperative, that "I should never act except in such a way that I can also will that my maxim should become a universal law". In other words, one may be subject to contradictory desires or interests, but these cannot be supported by reason.
