A Brief History of Everything

A Brief History of Everything is Ken Wilber's ambitious synthesis of evolutionary theory, systems thinking, and spiritual philosophy. The work traces the development of consciousness and complexity from the Big Bang through atoms, molecules, cells, organisms, and human societies, arguing that evolution operates across multiple dimensions simultaneously—physical, biological, psychological, and spiritual. Wilber proposes an "integral" framework that honors both scientific materialism and subjective experience, attempting to reconcile the apparent conflict between objective external reality and subjective inner awareness. The book became influential in transpersonal psychology, integral theory, and New Age philosophy, though it has also drawn criticism from academic philosophers and scientists for overreach and unfalsifiable claims.
