John Rawls's term "the veil of ignorance" refers to his thought experiment: Design a just society such that you'd be willing to live in it even if you couldn't choose who you were (rich, poor, healthy, sick, etc.) But that's about philosophy applied to real life, not about fiction. Yet I feel as though there's some connection between these two types of veils. Life itself makes a production of veiling things from us: the past, the future, and our context right now. We participate in veiling information from ourselves and others. I feel there are a lot of veiled knowns in philosophy. Questions could be raised, like: What are we really talking about when we talk about X? Sometimes a philosopher knows from the beginning of their public performance what they really want to talk about and is trolling the audience a little bit by hiding where their argument is leading. It can be fun narrativization to drive learning and engagement or it might just be deceptive and annoying.
