I've been thinking about this exact same problem. I also think that unthinkable for one person is not necessarily unthinkable for another - because people tend to create their own mental models, however robust or limited, to help them understand things. Sometimes the reason I have a difficult time learning something is simply because I haven't found the right mental model. Oh, and human language is a subpar medium to transfer thoughts and ideas. The effects of finding new mental models can be profound. It spurs advances in science but probably also has the potential to reposition our thinking when it comes to more abstract concepts like existence, god, etc. I think we can become an overall wiser species by searching for the mental models that fit us best.
