Ceteris paribus/BigelowVsCeteris paribus assumption/Qualification/Qualified law/Exceptions/Bigelow/Pargetter: Variant: "if there are no other disturbances": 1) Problem: this threatens to let a law become a tautology, which ultimately reads: "Things move in this and that way, unless they do not." 2) Problem: The range of a "qualified" law threatens to become so narrow that nothing is included by it anymore. On the other hand it will be said that a law has no positive instances at all if one interprets it strictly. ((s)> Cartwright). Solution/Bigelow/Pargetter: the mystery can be solved by understanding how laws contain modalities. Def Laws/law/Bigelow/Pargetter: are truths about possibilia.
Property theory/World properties/Terminology/Bigelow/Pargetter: contradictory predicates: do not correspond to any properties. E.g. round and square.
Accessibility: such possible worlds are then not accessible for one another. One is nomically impossible from the standpoint of the other. VsProperty theory/VsWorld-properties/Bigelow/Pargetter: this theory is faced with the accusation of circularity, but we hope to resolve the objection.
Determinables/Determinates/Johnson: stand in close logical relations: having a D-ate (determinate) entails having the corresponding D-able (determinable).
But not vice versa! Having a D-able does not require possession of a certain D-ate! But it does require possession of some D-ate from the area. BigelowVsJohnson, World properties: but this could not explain the asymmetry.
Solution/Bigelow/Pargetter: 2nd order properties.
Problem: our theory is still incomplete!.
Problem: explaining why quantities are gradual. And this is not about whether objects are the same and different at the same time.
New: The problem that we can also still say exactly E.g. how much they differ. Or E.g. that two masses are more similar than two others.
Plato: Plato solves this with participation.
Bigelow/Pargetter: we try a different solution.
