A conclusion could be drawn from the social character of ethics: where there are not at least two people, moral problems do not —or cannot— exist. This is the conclusion reached by some philosophers analyzed by the author in this study. If it is assumed, as Kant states, that every person has dignity, but
never a price, should it not be concluded, on this same vein, that every person should respect himself as if he were somebody else? The posibility of man's moral duties toward himself are here analyzed according to Kant's philosophy.
