The Beginning of Infinity: Explanations that Transform the World is a popular science book by the physicist David Deutsch first published in 2011. Synopsis Deutsch views the Enlightenment of the 18th century as near the beginning of an infinite sequence of purposeful knowledge creation. Knowledge here consists of information with good explanatory function that has proven resistant to falsification. Any real process is physically possible to perform provided the knowledge to do so has been acquired. The Enlightenment set up the conditions for knowledge creation which disrupted the static societies that previously existed. These conditions are the valuing of creativity and the free and open debate that exposed ideas to criticism to reveal those good explanatory ideas that naturally resist being falsified due to their having basis in reality. Deutsch points to previous moments in history, such as Renaissance Florence and Plato's Academy in Golden Age Athens, where this process almost got underway before succumbing to their static societies' resistance to change. The source of intelligence is more complicated than brute computational power, Deutsch conjectures, and he points to the lack of progress in Turing test AI programs in the six decades since the Turing test was first proposed. What matters for knowledge creation, Deutsch says, is creativity. New ideas that provide good explanations for phenomena require outside-the-box thinking as the unknown is not easily predicted from past experience. To test this Deutsch suggests an AI behavioural evolution program for robot locomotion should be fed random numbers to see if knowledge spontaneously arises without inadvertent contamination from a human programmer's creative input. If it did Deutsch would concede that intelligence is not as difficult a problem as he currently thinks it is. Deutsch sees quantum superpositions and the Schrödinger equation as evidence for a many worlds quantum multiverse, where everything physically possible occurs in an infinite branching of alternate histories. Deutsch argues that a great deal of fiction is close to a fact somewhere in the multiverse. Deutsch extols the usefulness of the concept of fungibility in quantum transactions, the universes and the particles they contain are fungible in their interactions across the multiverse structure. Deutsch explains that interference offers evidence for this multiverse phenomenon where alternate histories affect one another without allowing the passage of information, as they fungibly intertwine again shortly after experiencing alternate events. According to Deutsch, our perspective on any object we detect with our senses
