Never used a blog before, so we'll see how this goes...(It's Sara, btw).
No senses, eh? I believe that internal comprehension is completely separate from the physical being, meaning if all senses were eliminated, we would still be perfectly capable of absorbing experience and synthesizing the information we gain through that. Anything we are able to internally comprehend (intuitively, logically, emotionally, etc.), we could technically know. For example, human beings can instinctively sense hostility in one another or that they're being followed. Without being able to physically grasp that, we still know that information if we trust our gut enough. Our discoveries might not be as profound with this limited way of experiencing, but it's still quite possible to produce some sort of knowledge based on external observation while lacking sensory awareness.
