  A fourth hedonist response is concessive. It abandons altogether the thesis that pleasure is sufficient for value, while also continuing to insist that pleasure is necessary for value. Consistent with this response, one could claim that pleasure is conditionally valuable; that is, sufficient for value when and only when certain further conditions are met. These conditions could be specified either negatively (e.g., pleasure is valuable only when it does not arise from and is not directed at a bad deed or character state or state of affairs), or positively (e.g., pleasure is valuable only when its object exists, or only when its object is deserving of it). Modified forms of Altitude-Adjusted, Truth-Adjusted, and Desert-Adjusted Intrinsic Attitudinal Hedonism would have this structure (see Feldman 2004).
