[Phys-L] Nozick



Invariances[edit <https://en.wikipedia.org/w/index.php?title=Robert_Nozick&action=edit&section=8>]
In his 2001 work, Invariances, Nozick introduces his theory of truth, in which he leans towards a deflationary theory of truth <https://en.wikipedia.org/wiki/Deflationary_theory_of_truth>, but argues that objectivity <https://en.wikipedia.org/wiki/Objectivity_(philosophy)> arises through being invariant under various transformations. For instance, space-time is a significant objective fact because an interval involving both temporal and spatial separation is invariant, whereas no simpler interval involving only temporal or only spatial separation is invariant under Lorentz transformations <https://en.wikipedia.org/wiki/Lorentz_transformations>. Nozick argues that invariances, and hence objectivity itself, emerged through a theory of evolutionary cosmology across possible worlds <https://en.wikipedia.org/wiki/Possible_worlds>.[25] <https://en.wikipedia.org/wiki/Robert_Nozick#cite_note-25>
