Meta-rationality, presented in 'In The Cells of the Eggplant,' delves into the complex world of reasoning, introducing concepts of rationality, rationalism, reasonableness, and meta-rationality. The book defines "rationality" as the utilization of systematic, formal methods for thinking and acting, distinct from the broader sense of "any sensible way of thinking or acting. " It also explores "rationalism," which encompasses belief systems making exaggerated claims about the power of rationality.

The narrative then delves into "mere reasonableness," advocating for practical, coherent thinking and acting without strict formal rationality. Moreover, "meta-rationality" is introduced as informal, non-rational reasoning to best use reasonable, rational, and meta-rational methods contextually. With a focus on leveling up technical work with purpose and context, 'In The Cells of the Eggplant' offers readers an insightful exploration of rationality and meta-rationality, providing a fresh and engaging perspective on these vital concepts
