I think college/public education is more about indoctrination into a system.
Graduation - "gradual indoctrination" into the first degree.
What is interesting is what we wear across the world during graduation, a black robe and a square mortar board. Which I think was used by builders/stone masons to hold plaster and mold the structure.
The black robe goes back to Rome where the Roman clergy would wear these robes when attending COLLEGIA or today college.
Seems like the words and terms can all be traced back to indoctrination into the church/masonic system......no wonder we graduate with a degree..?
