Fittingness and Idealization

This note explores how ideal subjectivism in metanormative theory can help solve two important problems for Fitting Attitude analyses of value. The wrong-kind-of-reason problem is that there may be sufficient reason for attitude Y even if the object is not Y-able. The many-kinds-of-fittingness problem is that the same attitude can be fitting in many ways. Ideal subjectivism addresses both by maintaining that an attitude is W-ly fitting if and only if endorsed by any W-ly ideal subject. A subject is W-ly ideal when the most robust way of avoiding W-type practical problems is deferring to her endorsement.
