Introduction If you were to ask a human being and a bat, “What is it like to have a mind?,” you would expect to get unimaginably different answers. What is less expected is that if you asked four different people the same question, you could receive four unimaginably different answers. In 1974, philosopher Thomas Nagel famously asked […]

Purpose of this Post My general purpose for this post is to provide the interested reader statements directly from Paul D. MacLean’s magnum opus, The triune brain in evolution: […]
What does it tell us about the meaning of life when we can now say that for the first time in the known history of biology, we are witnessing the evolution of human beings with a concern not only for the suffering and dying of their own kind, but also for the suffering and dying […]
Consciousness is the perception of the purpose of life. Intelligence is the ability to successfully fulfill that purpose. Introduction The quadrune mind model states that the human brain is able to produce four distinctly different minds. Each mind has a different level of consciousness. The purpose of life is dramatically different for each mind’s level of consciousness. The […]
(Or, Metamorphoses of Mind) Introduction Quadrune mind is a secular, evolutionary model of spiritual consciousness. Until the 21st century, consciousness has “naturally” expanded on earth without active, intentional human intervention, but that is rapidly changing. With emerging neurotechnologies, neuroscientists and neuroengineers are capable of making radical changes to what the human brain is and what kind of mind(s) […]
The Reptilian Mind For the infant, disruption of its biological homeostatic balance needed to sustain life is “felt” at a physiological level as life-threatening, which it is. Similarly, for the infantile reptilian-minded “adult,” anything experienced as a threat to the status quo can also be “felt” as life-threatening, as much as asphyxiation would be for […]
Creationism is a dramatic story. The Supreme God commands the universe into existence, touching the earth to make humanity. But I think a more powerful story is the extraordinary evolutionary force that brings a universe into existence and gives rise to stars, life, and human consciousness. Every atom in our bodies was once stardust. Biblically, angels […]
Introduction The quadrune mind model of consciousness describes four levels of consciousness, or minds, which can emerge from the human brain. Each level of consciousness, when it is the dominant mind, will produce a distinct pattern of behaviors in our adulthood. These levels of consciousness are associated with different groups of our pre-human ancestors and stages of […]
Quadrune mind is a brain-based model of spiritual consciousness that describes three types of minds we have inherited from our evolutionary past: a behavioral reptilian-like mind, an emotional old mammalian-like mind, an intellectual new mammalian-like (primate) mind, as well as a mind only seen in human beings, our Human mind, which is capable of awe […]
Quadrune mind is a brain-based model of spiritual consciousness. One of its basic ideas is that our human brain lies on a continuum of brains over evolutionary time. The evolving brain carries over structural characteristics from older species to newer species. This progression of brains results in identifiable changes in minds, as well. A mind can […]
