An important constraint on the nature of intrinsic value---the “Supervenience Principle” (SP)---holds that some object, event, or state of affairs ϕ is intrinsically valuable only if the value of ϕ supervenes entirely on ϕ 's intrinsic properties. In this paper, I argue that SP should be rejected. SP is inordinately restrictive. In particular, I argue that no SP-respecting conception of intrinsic value can accept the importance of psychological resonance, or the positive endorsement of persons, in explaining value.
