My conjecture is that the abillity for characters to explain counting, equal quantities, and causal relations has been deliberately removed to allow those latter processes (with particular emphasis on the scientific method) to be used, to illustrate the general foundation of empiricism without needing to resort to an actually difficult problem where there might be genuine ambiguity about the answers. The lack of a common ground about causal reasoning and reality allows the process to described from the ground up, instead of resting on previous vague intuitions about reality and beliefs.
