1.) "If we are to have values at all we must accept the ultimate platitudes of Practical Reason as having absolute validity" (49).
2.) "If it [the Tao] is rejected, all value is rejected. If value is retained, it is retained. The effort to refute it and raise a new system of value in its place is self contradictory.
In this chapter C.S Lewis tries to make sense of our values and where the come from. He use morality and the idea of the Tao to make his argument. C.S Lewis brings in the Innovater he is sides with the Tao but says he is against it. The main argument for this chapter is morality versus someone's sentiments. He use a moral judments and our instinct as something that would break down Gauis and Titius' s methos of teaching. These things are factual and have some kind of basis. He talks a lot about the Tao a person values system and how we all can relate to it. He is trying to point out that we need the Tao and without our whole moral system would break down.
