Invariances[edit <

>]
In his 2001 work, Invariances, Nozick introduces his theory of truth, in which he leans towards a 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 <
