In education, you must learn the fundamental concepts for a subject before you can learn the advanced theory. The fundamentals are a Necessary Prerequisite for understanding the higher-level classes.

When it comes to understanding universal subjects like politics and religion, people with vastly different levels of subject matter expertise are expected to converse as peers. In order to understand ideas like universalism you must first have an understanding of the basic tenets of the major world religions and their commonalities. These are things that can be taught, but differences of opinion on this matter are not treated as simple disparities in education level.

In order for societies to evolve, there are necessary prerequisites for each step. If you have ever played the game Civilization then this point is obvious. You must invent the wheel and tame horses before you can invent the chariots that will let you dominate the ancient era.
