|Intrinsic: Intrinsic are properties which are not caused by relationships to other objects, e.g. to have a certain age. Intrinsic properties are not to be confused with essential properties, e.g. a certain age is usually not essential for an object. Extrinsic properties are, e.g. to be famous, that is to say, properties which arise from the fact that there are other objects, and these other objects have a relation to the object in question.|

Intrinsic properties/Putnam: problem: if they are rejected, then there is no external thing or event specifically, essentially or intrinsically connected to any relationship that it may have to other things (our thoughts included) - so reference becomes an occult phenomenon.
Intrinsic explanation/Putnam: if there were intrinsic statements within the world, the world would be like a ghost - then materialism cannot be true.
