"Human Faith Within a Conscious Biosphere" describes consciousness as the system that operates the biosphere. As readers will discover, consciousness is not a single essence. Consciousness came with creation; humans and other sentient beings just participate in it. Individual participation in consciousness enables individuals' needs by engaging the biosphere. Faith is what we think we know for sure, and it is not limited to religion. It supports essential social systems. Evolution of language was humanity's greatest advance in participation in consciousness. Human language is the basis for human thought; words are abstractions that individuals internalize for abstract thinking. Language empowered the collection of knowledge into what the book describes as consensus reality. Consensus reality grows as it passes from generation to generation, and human participation in consciousness grows along with it. This book explains all of that, and much more! Throughout his impactful book, author Dale Segrest offers the enlightening reminder that the purpose of consciousness is to enable humans to function in the biosphere. The biosphere is the environment that produces human faith. Individual faith develops in stages; the biosphere is the environment that provides the sources of faith. Humans are observers in the biosphere. The nagging philosophical problem of dualism is a semblance, a mistaken conceptualization that results from the misleading perception of internal/external by all observers.
