In a book, a philosopher claimed that this phenomenon’s nature as “inconsistent multiplicity” is obscured by the operation of “count-as-one.” This phenomenon is the first word in the title of that book, which was attacked by Roger Scruton for (10[1])misapplying Paul Cohen’s method of forcing. Another philosopher distinguished between a conscious form of this phenomenon, which is the source of all negation, and an unconscious form that is the pure plenitude of positivity. The way that “ruptures” in this phenomenon (-5[1])create the possibility (-5[1])of perceiving truth (-5[1])is modeled using Zermelo–Frankel set theory in a book by Alain Badiou (“ah-LAN bah-DYOO”) that (10[1])pairs this word with “event.” (10[5])Another (10[1])philosopher (10[1])showed how the (10[2])“for-itself” form (10[1])of this phenomenon (-5[1])can lead to “bad faith.” For 10 points, name this word that a Jean-Paul Sartre book (10[1])pairs with “nothingness.” (10[4])■END■ (10[7])
