  One sort of hedonist response to an insufficiency objection is to accept that the objector's case is an instance of pleasure, but then to claim that it is sufficient for value. This response is underpinned by insistence on the wider thought that any pleasure is sufficient for value. Consistent with this, but rather concessively, it could also be claimed that pleasure is sufficient for only very little value, and that substantial or major value is present only if further conditions are met. Such further conditions might concern the extent to which the pleasure is ‘higher’ rather than ‘lower’, whether its object exists, or whether its object merits pleasure. Feldman (2004) has formulated and sympathetically examined several views that have this sort of structure, including Altitude-Adjusted, Truth-Adjusted, and Desert-Adjusted forms of Intrinsic Attitudinal Hedonism.
