We argue for asymmetries between positive and negative partiality. Specifically, we defend four claims: i) there are forms of negative partiality that do not have positive counterparts; ii) the directionality of personal relationships has distinct effects on positive and negative partiality; iii) the extent of the interactions within a relationship affects positive and negative partiality differently; and iv) positive and negative partiality have different scope restrictions. We argue that these asymmetries point to a more fundamental moral principle, which we call Morality's Harmonious Propensity. According to this principle, morality has a propensity toward preserving positive relationships and dissolving negative ones.

偏袒、不对称与道德的和谐倾向

我们主张积极偏爱和消极偏爱之间的不对称。具体来说，我们捍卫四个主张：i）存在一些没有积极对应物的消极偏爱形式；ii)人际关系的方向性对正偏和负偏有明显的影响；iii)关系中相互作用的程度对积极和消极偏爱的影响不同；iv )正面偏爱和负面偏爱有不同的范围限制。我们认为，这些不对称指向了一个更基本的道德原则，我们称之为道德的和谐倾向。根据这一原则，道德具有保存的倾向。积极的关系并化解消极的关系。
