"In fact, scientifically speaking, you can only be certain that you yourself are experiencing something." How can you be certain?

  Has anyone, anywhere, ever had an experience of someone else's experience? Until you can directly experience someone else's experiential state, the best you can do is posit that they even have one, let alone trying to talk about what it might be like. In philosophical terms, this is the problem of Epistemic Asymmetry. It's part of the so-called Hard Problem of Consciousness.
