About race: a) what does it mean to say that race is a floating signifier? (to answer this part of the question, you have to define what a floating signifier is and explain how race works as such) b) using the example of the Haitian revolution, explain what the phrase “race is an illusion that has power” means? (you do not need to explain what ‘the unthinkable’ is… but it would help to know what it means)
