Meillassoux and Non-Manifestation

I only just got a hold of Meillassoux’s Après la finitude last week (the library at my supposedly bilingual university only had the English translation) and was pleasantly suprised to find this :

[…] comment un être peut-il manifester l’antériorité de l’être sur la manifestation? (p.48)

(“how can a being manifest the anteriority of being over manifestation?”)
