Pirsig describes evolution as the moral progression of these patterns of value. For example, a biological pattern overcoming an inorganic pattern (e.g. bird flight which overcomes gravity) is a moral thing because a biological pattern is a higher form of evolution. Likewise, an intellectual pattern of value overcoming a social one (e.g. civil rights) is a moral development because intellect is a higher form of evolution than society. Therefore, decisions about one's conduct during any given day can be made using the Metaphysics of Quality. Pirsig is not proposing criticism or responsibility, but acceptance, and pure absorption: "When he wrote it he felt momentary fright and was about to strike out the words "All of it. Every last bit of it." Madness there. I think he saw it. But he couldn’t see any logical reason to strike these words out and it was too late now for faintheartedness. He ignored his warning and let the words stand."-ZMM, Ch.20
