the reality of abstractions and the concept of emergence, arguing that high-level explanations are often more vital than microscopic physical details. While reductionism suggests that everything should be explained by its smallest parts, the author demonstrates that phenomena like mathematical truths or human ideas possess a quasi-autonomous existence that physics alone cannot account for. Using the example of a domino computer, the text illustrates how an abstract concept like primality can be the only meaningful reason for a physical event. This logic extends to morality and philosophy, suggesting that right and wrong are objective truths discovered through the quest for good explanations. Ultimately, the author contends that emergence is essential to the world’s explicability, allowing knowledge to grow beyond the limits of its physical origins.
