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 […]

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 […]
If we look at the conflicts between people reported today in the news and recorded in world history books, we might be able to create a fairly long list of causes. Interestingly, for every cause there is an opposite and equal “re-cause.” Like the song Everyday People says, many people will always look for an […]
(We Make the World Better) There is an essential point that may sometimes get lost in our many examples of the harm caused by behaving from a pre-Human mind: throughout evolution and human history, we are moving toward becoming more loving and better people; i.e., more Human-minded. The quadrune mind model is a melioristic model, […]
(Understanding What Is Good, Great, Evil, and Human) Introduction Most of us believe that people possess one mind. Sometimes that mind has the wisdom and courage to declare in the face of widespread civil violence: “We are not enemies, but friends. We must not be enemies”—a thought that surely comes to us from “the better angels of our nature.” Other […]
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 […]
The quadrune mind model of consciousness states that the human brain can support not one, but four distinctly different minds. Three of these minds are associated with parts of our brain that we share with our evolutionary ancestors: reptiles, herd mammals, and primate mammals. The fourth mind in this model, associated with the newest part […]
