Particularism is a philosophical and ethical concept that emphasizes the importance of specific contexts and individual circumstances in moral decision-making. Unlike universalism, which advocates for applying the same moral principles to all situations, particularism suggests that the rightness or wrongness of an action can depend on the unique details of each case. In the realm of ethics, particularism is often associated with thinkers like Jonathan Dancy, who argue that moral judgments should be based on the particulars of a situation rather than fixed rules. This approach allows for a more nuanced understanding of morality, recognizing that different contexts can lead to different ethical outcomes.
