Another contribution of pragmatism to value theory is the idea of contributory goods with a contributory conditionality. These have the same qualities as the good thing, but need some emergent property of a whole state-of-affairs in order to be good. For example, salt is food on its own, but is far better as part of a prepared meal. In other words, such goods are only "good" when certain conditions are met. This is in contrast to other goods, which may be considered "good" in a wider variety of situations.
