Rejecting Voltaire?

Emmanuel Macron’s election speech was reassuring. Intriguing that he took his long walk to the podium with the European anthem playing, rather than the French. One thing that disappointed me: He rejected fear, lies, division, fatalism, all good things to reject, but I just can’t get behind

Nous ne céderons rien à… l’ironie…

I don’t see how he can claim to be defending the values of the Enlightenment.

The word he used at the beginning interested me:

Je sais qu’il ne s’agit pas là d’un blanc-seing.

I’ve never heard the word blanc-seing before. It’s funny that we use a french phrase, carte blanche, for the same thing.
