Translation of "Knowns" in French

There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns – the ones we don't know we don't know.

Il y a des certitudes connues ; il y a des choses que nous savons savoir. Nous savons aussi qu'il y a des ignorances connues ; c'est-à-dire que nous savons qu'il y a des choses que nous ignorons. Mais il y a aussi des ignorances inconnues - celles dont nous ignorons que nous les ignorons.
