The Beginning of Infinity

Physicist David Deutsch argues that all progress stems from "the quest for what I call good explanations," defining knowledge as information with good explanatory function resistant to falsification and viewing the Enlightenment as near the beginning of infinite knowledge creation. The book establishes that "the real source of our theories is conjecture, and the real source of our knowledge is conjecture alternating with criticism," arguing there is no necessary limitation to human progress. Deutsch extols philosophical optimism—while problems are inevitable, solutions will always exist provided the right knowledge is sought—covering science, philosophy, AI, culture, morality, and political institutions unified by the power of explanations.
