First, two aspects of the partiality issue are identified: (1) Is it right/reasonable for professionals to favour their clients interests over either those of other individuals or those of society in general? (2) Are special non-universalisable obligations attached to certain professional roles?Second, some comments are made on the notions of partiality and reasonableness. On partiality, the assumption that only two positions are possible – a detached universalism or a partialist egoism – is challenged and it is suggested that partiality, e.g. (...) to family members, lies between these two positions, being neither a form of egoism, nor of impersonal detachment. On reasonableness, it is pointed out that reasonable is an ambiguous concept, eliding the notions of the morally right and the rational. (shrink)
