You can't be nothing if you think you're something, even if you think that something is nothing because no matter what you think, you're a thinking thing, or as Descartes put it, "I think, therefore I am," and so are you, really.
Hûn bifikirin hûn tiştek in, hûn ne tune ne. Hetta hûn bêjin tiştek jî ne tiştekê, hûn çi bifikirin bifikirin, hûn dibin tiştekî ku difikire. Wek Descartes gotî  ''Ez difikirim lewra ez heme.'' û hun jî wisa.
