Until the End of Time: Mind, Matter, and Our Search for Meaning in an Evolving Universe

by Brian Greene

The human capacity to respond with great variety is testament to the core principles that have guided our exploration thus far: the entropic two-step and evolution by natural selection. The entropic two-step explains how orderly clumps can form in a world that is becoming ever more disordered, and how certain of these clumps, stars, can remain stable over billions of years as they produce a steady output of heat and light. Evolution explains how, in a favorable environment such as a planet bathed by a star’s steady warmth, collections of particles can coalesce in patterns that facilitate complex behaviors, from replication and repair, to energy extraction and metabolic processing, to locomotion and growth. Collections that acquire the further capacities to think and learn, to communicate and cooperate, to imagine and predict, are better equipped to survive and hence to produce similar collections with similar capacities. Evolution thus selects for these abilities and, generation upon generation, refines them. In time, some collections conclude that their cognitive powers are so remarkable that they transcend physical law. Some of the most thoughtful of these collections are then bewildered by the conflict between the freedom of will they experience and the unyielding control of physical law they recognize. But the fact is there is no conflict because there is no transcending of physical law. There can’t be. Instead, the collections of particles need to reassess their power...
