Normative Reasons for Action: The Situationist Approach

To justify one's actions is to provide reasons, specifically, normative reasons that serve as their foundation. This process involves three key elements: facts, beliefs, and desires. However, the relationship between the latter two (often understood as motivating and epistemic reasons) and the former (the facts) remains a matter of ongoing debate. This paper examines one distinctive approach to addressing this interplay: situationism. Distinct from perspectivism, casuistry, or plain contextualism, situationism offers a framework for understanding the proper place of normative reasons. The paper offers a nuanced defense of the irreducibility thesis—the claim that the truth of normative propositions cannot be reduced to the truth of non-normative facts about the world. In doing so, it argues that each of the three elements plays an essential role in shaping normative reasons for action. Yet, when isolated or taken "on its own," any one of them can be used to justify morally reprehensible courses of action—whether by individuals or collectives. The situationist perspective, by emphasizing the structure of normative rationality, offers a way to better foresee how and where such distortions occur. Ultimately, this approach may help illuminate the wrongness of certain human endeavors, that is, to counter the potential tyranny of any of the three elements in play.
