This isn't a debate and I'm not stating a theory, I'm telling you what you don't know of and apparently don't understand. Read once again what I've posted above and perhaps then you'll move on from "the mind can do whatever it wants" to the concept of conceptual thought as a whole. Try to understand what I've already said: conceptual thought is the form of thought used by our mind, naturally and most optimally in all aspects while in this form and mind. You must have felt it at one point in time or another, think about how you think naturally.
This isn't a theory, this isn't an idea, it's a fact that I'm stating simply because it exists.
