|Property: what can be ascribed to an object in order to distinguish it from other objects. In philosophy, there is debate about whether properties exist or whether "bare particulars" exist. Expressions for properties are predicates. Not every predicate will refer to a property. See also quantification over properties, 2nd order logic, HOL, completeness.|

Ryle: Description decides whether a property is necessary or contingent! (Kripke: but not all properties accidental, some essential.)
Nature/Kripke: some properties are essential: E.g. 9 is an odd number.
Definition essential property: If we consider a property to be essential to an object, we usually mean that it would have applied to an object in any case in which it would have existed.
Relevance of properties depends on theory (Vs sheaf theory)
The biblical story does not provide any necessary properties of Moses, so he could have lived without accomplishing any of these things.
Properties: "essential" perhaps not the most important - no theory distinguishes by relevance.
I do not want to say that only the origin and substance are essential.
Properties: There could even be a substance that has all the identifying properties, and yet is not gold, e.g. fool’s gold.
Each property could turn out to be wrong, therefore it is not a bundle concept.
General names like "cat" do not express any property.
Wolf II 212
Kripke essential property/Meaning/Intention e.g. novel: it is not important whether the hero really was the Messiah, but it is important that the deeds apply to the intentioned hero - has nothing to do with the principle of charity.
