Moral particularism

Overview
Moral particularism is a theory in normative ethics that runs counter to the idea that moral actions can be determined by applying universal moral principles. It states that there is no set of moral principles that can be applied to every situation, making it an idea appealing to the causal nature of morally challenging situations. Moral judgements are said to be determined by factors of relevance with the consideration of a particular context. A moral particularist, for example, would argue that homicide cannot be judged to be morally wrong until all the morally relevant facts are known. While this stands in stark contrast to other prominent moral theories, such as deontology, consequentialism, and virtue ethics, it finds its way into jurisprudence, with the idea of justifiable homicide, for instance. In this case, the morally relevant facts are based on context rather than principle. Critics would argue that even in this case, the principle still informs morally right action.

For example, the law of contradiction states that nothing can both have a certain property and not have it. This is evident as soon as it is understood, but it is not so evident as that a particular rose which we see cannot be both red and not red. (It is of course possible that parts of the rose may be red and parts not red, or that the rose may be of a shade of pink which we hardly know whether to call red or not…
