|Modal properties: are properties that are not attributed actually to an object, but are attributed in a possible world. A modal property is e.g. the property of being happier under other circumstances. The question is whether an object in the actual world must have a certain quality in order to have different properties in another world. See also modal logic, modal realism, possible worlds, centered worlds, contingency, possibility, necessity, properties, extensionality._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Nature/essence/Kripke: E.g. Statue: The statue and the piece of clay are two items.
The fact that the piece of clay has a modal property, namely, "to be a thing that might have been spherical" is the statue missing.
VsKripke: that sounds initially odd: E.g. when I put the statue on the scale, do I measure then two objects?
E.g. Equally strange is it to say, a human being is not identical with the aggregation of its molecules.
Intrinsic properties/Putnam: E.g. Supposing there are "intrinsic connections" to my thoughts to external objects: then there is perhaps in my brain a spacetime region with quantity-theoretical connections with an abstract object which includes some external objects.
Then this spacetime region will have a similar quantity-theoretical connections with other abstract entities that contain other external objects.
Then the materialist can certainly say that my "thoughts" include certain external objects intrinsically, by identifying these thoughts with a certain abstract entity.
Problem: if this identification should be a train of reality itself, then there must be real essences in the world in a sense that the set theory cannot explain.
Nature/essential properties/PutnamVsKripke: Kripke ontology presupposes essentialism, it cannot serve to justify him.
Term/Possible World/Putnam: modern semantics: functions about possible worlds represent terms - e.g. the term "this statue" unequals the phrase "this piece of clay" - PutnamVsPossible Worlds: Question: Is there in the actual world an object to which one of these terms significantly and the other only accidentally applies to? - Possible worlds provide too many objects.
PutnamVsKripke/PutnamVsEssentialism: its ontology presupposes essentialism, it cannot justify it - modal properties are not part of the materialistic means of the world - but Kripke individuated objects by their modal properties - essential properties/Putnam: I have not shifted them into "parallel worlds" but instead into possible states of the actual world - (other liquid than H20 water) - which is insofar essentialist that we have thus discovered the nature of water - we just say water should not be anything else (intention) - that is our use and not "built into the world" (intrinsic) - (Kripke ditto) - VsMaterialism: this does not help the semantic reading because it presupposes reference - (materialism wants to win reference from "intrinsic" causal relationship)._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
