>Because you experience your own and therefore assume that other people (and probably many animals) have experiences do to the similarity in behavior and biology. This is called 'studying it'. Different experiences do not preclude understanding. You can't imagine "what it's like", but "what it's like" is always a biological process of analogy. And you can convey understanding of subjective experience through analogies. That's the whole point of art. Just because you can only get arbitrarily close to understanding something doesn't mean you can't understand it. By that measure, you don't even understand your own senses - they are transient, fleeting, and reflexive. But we're not supposed to deny the entire concept of knowing and understanding, are we? Ok, so you don't see more than three primary colors. Doesn't mean you can't understand it. You know the difference between being in a room with only red light versus being in a room with white light? Then you know what it is to see more colors. Personal anecdote: I've felt things in dreams that I've never felt awake. I can imagine sensations I've never experienced while awake. So I can't believe that it's impossible to feel things outside of our current experiences or to experience things arbitrarily close to as how others do. Especially since we can hook electrodes up to our brains, do computations outside, and arbitrarily increase the state space of our brains. So like I said: out of reach doesn't mean impossible.
