Popular calls for education reform to produce 'functions' of creativity only provide an ironic outline of what is missing from this functional education system: the human element. Education must produce humans. Creativity is a natural expression of humanity. In order to teach someone what it means to be human, there must be some understanding of what this is or how it might look.
The appeal by Lewis to a transcendent universal standard creates the space required for a democratic approach to education reform. If the standard is universal, every person has some idea of what it might look like and can participate in the process of building a new system. On the other hand, if the standard is arbitrary, then only those with power, authority, and credentials have the ability to propose changes for reasons only they can understand.
