Normatywność pojęcia przyjaźni i jego miejsce we współczesnych teoriach etycznych

Friendship for ages has been viewed as a specific kind of relationship with a positive moral value. In my article I am trying to answer the question of the source of that value. Among many other questions I enquire whether such a normative (positively valuing friendship) approach presumes that any action out of friendship must be morally good and morally right; whether such relationship is exclusive; whether it requires a special kind of engagement and high quality moral dispositions or it is rather an all inclusive relationship and independent of moral traits and dispositions; and finally I ask how the contemporary ethical theories which highly value impartiality manage to explain the nature of the fascinating phenomenon of friendship and its specificity.
