What is the verdict on the "inner monologue?" Can humans be split into groups of those who can visualize their thoughts and those who can't? Like many, I was surprised, when this topic started surfacing on the internet, to learn that some people claim not to be able to conjure mental images at will.
I thought perhaps those people don't understand the question. Perhaps those who claim we can imagine pictures aren't explaining what it is we are doing when we think. Are there really varying degrees of conceptualizing?
If so, how do those that claim they can't visualize at all ever invent things? How can they understand concepts like beauty, abstraction, and recursion? Do they not have an inner voice when they read or think? This topic is well-discussed and documented, but what is really at play?
