Change is a trait of reality, but there is a uniform pattern in which change takes place. Without some degree of uniformity there could be no norms or no predictability and without these the task of education would be impossible. If there is constant change, then it follows that there is uncertainty as to how the changing universe will turn out. The future is not merely the unfolding of a reality already antecedently complete. The future is fraught with contingency.
Events seem to be constantly taking a novel turn.
The universe is still being made. It is a sort of a world with the lid off. Reality itself is incomplete. It is a world in which the book of Genesis is still being written. Educators will have to encourage pupils to be creative.
