Consciousness is not something that can be measured, quantified, or reduced to neural, brain-based processes. It is not something confined to the human mode of being in the world, nor can it be identified solely with what many religions claim to be the unique quality of life after death. Consciousness transcends all the names and labels that we put on it. It does not belong to the sphere of observable material reality; however, it is structured within universal life, and evidence for it can be gleaned from several of evolution’s creations.
