[D-G] eternal truth & states of affairs

[Johnatan Petterson]

do someone here knows why G.Deleuze talks of
physics' laws, as 'eternal truths' (vérité éternelle)
saying 'we should talk' of 'eternal truth' instead than of 'laws of nature',
because the word 'law' has a moral after taste .

was Deleuze attacking the morality of his times with the notion of an
eternal truth?

considering his works like ATP which gave a physician turn to many branches
of the sciences,
there must be something deeper in Deleuze than criticizing the label "laws
of nature",
ok but why then to return to such a word like eternal truth,
which enters into contradiction with his conception of philosophy as
creation by concepts?

as well i wish i knew what he meant as a reality of reference by the name:
<<états de choses>>
(states of affairs or states of things)


?

anyone?
