@Lustig Andrei,

If reality is an illusion, then it's no longer 'reality.'
Once you define 'nothing', it becomes something.
Such observations are central to "post-modernism". They can be traced via Hegel's dialectic (thesis, antithesis, synthesis) , Wittgenstein's "language games", through to Derrida's "aporia". The movement is iconoclastic with respect to traditional (analytic) philosophy and has consequently many opponents, despite respectable protagonists such as Richard Rorty.
Interestingly to me, its implicit rejection of "the law of the excluded middle" seems to reflect some findings in modern physics such as "wave-particle duality". (Hence the background to the Niels Bohr quotation above).
