While advances in cognitive science have provided a series of significant opportunities for ethical inquiry,they also bring about challenges to traditional approaches to ethics and to some ethical views. Since the 1920 s,situationist experiments in social and personality psychology have been deemed to"dissolve"the concept of character,and in the last twenty years,some philosophers have gone on to argue,using relevant results in cognitive science,that virtue ethics is empirically inadequate when it takes character to be central to ethics.This paper aims to show that this claim is not decisive from the perspective of either empirical research or philosophical reflection,and that the Aristotelian virtue ethics is endowed with adequate conceptual resources to answer this kind of challenge. In addition,by focusing on the case of the situationist challenge,this paper is further intended to inquire into the question of how the relationship between empirical science and philosophical reflection is to be construed.
