scientific advancement is driven by the search for objective explanations rather than mere predictive accuracy. While testability is a vital part of the scientific method, the author contends that it is insufficient on its own because even unscientific myths or rules of thumb can produce verifiable predictions. The source critiques instrumentalism, suggesting that reducing science to a set of predictive formulas ignores the underlying reality that makes those predictions possible. Through the analogy of a conjuring trick, the author illustrates that true progress occurs only when we move beyond outward appearances to solve the conceptual conflicts within our theories. Ultimately, the text defines science as a rational pursuit of knowledge that seeks to understand the physical world through creative conjecture and the resolution of problems.
