 Others attempt to avoid over-generating truth-makers by appealing to the notion of essence, a notion that purports to be far more discriminating than necessitation (Fine 1994; Lowe 1994). The difference in grain between these notions becomes evident when we reflect that although it is (supposed to be) necessarily the case that if Socrates exists then his singleton does too, it isn’t part of the essence of Socrates that he belongs to this set. If these notions really are different then we will need to distinguish between those entities that merely necessitate a true claim on the one hand and those that are also part of its essence on the other. This suggests a strategy for ruling out spurious truth-makers: they’re the ones that only necessitate true claims, whereas the real ones are also implicated (somehow) in the essences of the claims they make true.
