The school was a great, open field. The Great Teacher watched from the sunlit hill.
Three teachers stood before his class, next to a great stack of bricks -- special bricks, that were called "facts."
The first teacher picked up a fact-brick and held it out. One at time, the students approached and took the offering from his hands. When each student was supplied, the teacher commanded: "Now, keep returning to me and put your bricks in a stack. You will make the biggest pile possible, for I will hand you many, many bricks before the sun falls."
The Great Teacher frowned.
