Pirsig aims towards a perception of the world that embraces both sides, the rational and the romantic. This means encompassing "irrational" sources of wisdom and understanding as well as science, reason and technology. In particular, this must include bursts of creativity and intuition that seemingly come from nowhere and are not (in his view) rationally explicable. Pirsig seeks to demonstrate that rationality and Zen-like "being in the moment" can harmoniously coexist. He suggests such a combination of rationality and romanticism can potentially bring a higher quality of life.
