Christmas is a primary method of indoctrinating people into scientific rationalism. The childhood imagination is fully engaged by this effort, unlike any other, to create the illusion of Santa Claus. As a kid it is a sort of bliss. Then as a sign of the transition to adulthood the growing child comes to realize there is no Santa. No time for mourning though, the growing youth is immediately brought into the fold and encouraged to help maintain the illusion for the younger children. The work is complete, the nature of fantasy and reality is established.
