Summary |
One influential way to develop the idea
that laws of nature are metaphysically robust connections between natural
properties is to say that laws hold in virtue of the instantiation of an
irreducible second-order relation, the so-called relation of nomic
necessitation, obtaining between universals (conceived of as first-order
properties). When instantiated, this necessitation relation is also meant to
govern or produce the (nomic) regularities in our world. Armstrong, Tooley, and
Dretske have defended this view of laws (referred to as the DTA theory) as necessitation relations between
universals. |
