|Natural Laws||III 137
Laws of Nature/LoN/Natural Law/Science/Form/Identification/Armstrong: theoretical identification of water and H2O not a law of nature - two all-quantifications on molecules and water - each law of nature must have double-digit form of premise-conclusion - Ontology: what entities exist is inextricably linked with law of nature - but also distinguishable from it.
LoN/Armstrong: contingent - but not because they are discovered - the distinction a priori/a posteriori an epistemic one.
LoN/Armstrong: not true statements of law, but truth-makers - VsHume: strong LoN: contain regularities, but cannot be reduced to them (because dispositions do not always show) - LoN: can be identified with relations between universals (properties) - Camp: realistic view - E.g. possession of a property leads to possession of another property - LoN/Armstrong: contingent! - But the regularity seems to be contained analytically.
LoN/Armstrong: Relation between categorical properties (not dispositional ones) - PlaceVs: smuggles modality in (because the relations then have to be intentional or modal).
LoN/Armstrong: no causal factors - exists only when instantiated - logical consequence (that three values of volume, pressure, temperature always are connected) is not because of the law! (Boyle's law is no law of nature).
