The Beginning of Infinity is David Deutsch’s sweeping argument that the engine behind all meaningful progress—scientific, technological, moral, and cultural—is the creation of good explanations: ideas that are hard to vary without breaking what they explain. He rejects empiricism and inductivism as myths about how knowledge is “derived” from experience, insisting instead that knowledge grows through conjecture and criticism, in a fallibilist tradition that began with the Enlightenment.
Deutsch connects this epistemology to a bold worldview: problems are not only solvable in principle; they are the expected condition of human life. The biosphere does not “support” us—people support themselves by transforming environments with knowledge. He extends the claim across domains: evolution and memes, universality and computation, optimism and politics, objective beauty and art, and quantum theory as a multiverse explanation. The result is a unified case for an open-ended future—so long as societies preserve criticism, tolerate dissent, and keep improving explanations.
