I recently was thinking about what life might be like if we were unable to visualize thoughts in our minds. Imagine if we actually had to draw out our thoughts on paper in order to "see" them, or speak sounds to hear them. Our brains provide us with such a vivid canvas on which we can easily illustrate in two or three dimensions, internalized within ourselves. It also provides us with a stage in which we can animate anything or anyone in any way we want, and the orchestra to conjure up whatever audio we like.
What if we had these capacities taken away? Could we somehow still get by based only on what we perceive with our eyes and ears?
