The Bottom of 64

Demand is structured by the signifier. Lacan says that three lines up from the bottom of 64 because we know that demand is need expressed in language. But that's also why it can't be taken literally, which is to say that if you hear a demand, a demand for a blanket, even if the child has words and says, please bring me the blanket, you can’t take itliterally," she said. "Every demand ... always exceeds the expression of need"
