Here's another one from Jonathan Glasgow that I'll just quote his own description of:
We are all simultaneously struck by an agent that causes us forget our systems of racial classification. Any time we start to racially classify ourselves, our cognitive apparatuses short-circuit. One hour later, cognition reverts to its pre-amnesiac state, and racial classification resumes.
(Again, as with several of these, if you think races don't exist, you'll say they continue not to exist through this. But this question is for those who think they do exist.)
Do races stop existing for that period of time and then come back into existence, or does something keep them in existence during the interim period? If so, what generates their existence?
