The Big Idea
C.S. Lewis argues that abandoning the Tao, the universal doctrine of objective value, fundamentally destroys human nature. When education teaches that moral sentiments are purely subjective, it produces men without chests unable to regulate their base appetites through reason. Ultimately, the quest to conquer nature without the restraint of objective morality allows a small group of Conditioners to mold future generations according to their own arbitrary whims, effectively abolishing mankind as a rational, moral species.
