How Close Do You Think We Can Get to Understanding Someone's Reality?

Can we truly understand someone else's reality without being in their thoughts and feelings, or can we just make a judgment of it? I think the best way to come as close to that as possible, I would say, is reading literature. Watching great drama, read James Joyce. And so if you want to understand consciousness itself, what it's like to be a human being, engage deeply with other human beings.
