Abstract
This paper develops an account of existential choices and their role in practical reasoning. In contrast to other views that attempt to make sense of existential choices as a type of rational choice, the proposed account takes them to be choices among the normative outlooks that determine the reasons we have, and as such are nonrational. According to the argument in the paper, existential choices bring to light a feature of all choices, that they are made against the backdrop of a normative outlook, which grounds the rationality of the choice but is not itself rationally determined.
