Stage Three minds encompass all the vertebrate minds, including fish, amphibians, reptiles, birds, and mammals. These minds can think about objects—about concrete things in the world—so we call them “object-thinking” minds.

Stage III Minds: The Object-Thinking Minds

Let’s talk a little more about those four stages of minds, because hidden within them is a truly momentous revelation—a revelation hidden within the transitions between stages.The emergence of each stage of thinking involved a mental revolution—a dramatic expansion of the scope of thinking, which we can think of as a dramatic expansion of the scale of chaos that the mind can adapt to. This helps us understand the transitions between stages.

Adapting To Chaos

The physical component that performs the thinking in point minds is the molecule. Point-thinking minds got smarter over time by diversifying the specific molecules they used to think with, and the most powerful point minds flaunt the greatest diversity of molecules.Pattern-thinking minds use neurons to think with, and the most powerful pattern minds flaunt the greatest diversity of neurons. Object-thinking minds think using specialized networks of neurons, and the most powerful object minds flaunt the greatest diversity of networks.

From Molecule, To Neuron, To Network: Diversity

Stage One minds are the simplest minds on Earth, including the very first minds that ever existed. We’ll call them “point-thinking” minds, because these minds think in terms of points in space. All microscopic single-celled creatures, including archaea, bacteria, and protozoa, boast point-thinking minds.

Stage I Minds: The Point-Thinking Minds

Stage Two minds can think about patterns, so we’ll call them “pattern-thinking” minds. All invertebrates, including jellyfish, worms, and insects, possess pattern-thinking minds.

Stage II Minds: The Pattern-Thinking Minds

But the journey of the mind—so far—is the chronicle of purpose winning ever-more daunting battles with chaos. Minds defeat chaos by ascending to new stages of intelligence, autonomy, and awareness. Each new stage of thinking in the universe—point-thinking minds, then pattern-thinking minds, then object-thinking minds, then idea-thinking minds—masters a broader scope of physical reality than the stage before.

Minds And Chaos

Thus, the three-billion-year-journey of the mind shows that, over and over again, minds develop an expanding variety of thinking elements that enable minds to process a greater variety of inputs, and convert them into a greater variety of behaviors according to a greater range of valuations. This applies to the human supermind, too; the best way for a supermind to get smarter is to diversify the people within it.

Diversity Is The Ticket To Intelligence

Social media, economic globalization, and cultural globalization can all be understood as a natural and inevitable part of the journey of the mind as it works out the new structures and dynamics that may one day bind together the community of human superminds into a hypermind. Instead of thinking about ideas, this emergent hypermind might think in terms of ideologies.

The Ideology-Thinking Minds

Indeed, if we look around our world right now, we see the first hints that the human supermind is pushing toward the emergence of a fifth stage of minds, which we might call “hyperminds.” What is the new form of physical connectivity driving the formation of hyperminds? The internet.

Stage V Minds: The Hyperminds

And why are we here? And what should we do with the life we’ve been given? The three-billion-year journey of the mind offers new answers to these very old questions.We are part of a never-ending dance of purpose and chaos—the random, aimless churn of physical matter. The dynamics of minds produce purpose in the universe, and the goal of purpose is to overcome the relentless, destructive power of chaos.

Purpose And Chaos

All mammals, birds, reptiles, amphibians, and even fish are conscious; they all possess the necessary neural circuitry to produce the dynamics of consciousness. But human consciousness is different from the consciousness of any other animal because humans possess something extra, a layer of thinking that operates on top of the dynamics of consciousness, the layer that renders us an idea-thinking supermind. This additional layer is language.

Language And Consciousness

The journey of the mind teaches us something unexpected about the human self—and about self-awareness. We are the only creature on Earth capable of self-awareness, and there’s a very simple reason why: self-awareness requires language. It’s not the particular words themselves that are essential, but rather it’s the dynamics of language that are so important.

Language And Self-Awareness

Only one species has reached the fourth stage of thinking, and that’s us, homo sapiens. We are the only creatures who can think about ideas. But here’s the thing—the idea-thinking mind is not the human brain. What sets humans apart from all other creatures in nature is that an idea-thinking mind is comprised of an entire community of human brains.

Stage IV Minds: The Idea-Thinking Minds

And finally, there’s us, the idea-thinkers—where did we come from? Object-thinking minds teamed up with one another to form a community of object minds. This network of object minds—this supermind—can think about ideas.So what form of physical connectivity bound together human brains into a supermind? Language. Language empowers the sapiens supermind to think about ideas.

The Supermind And Language

This makes clear that human beings are not the ultimate destination of the journey of the mind. Many people think of consciousness as the pinnacle of thinking in the universe—but that’s not true at all. Consciousness emerged in fish somewhere around a half-billion years ago. Two more far-reaching mental innovations emerged long after consciousness, including language and the human self. This may come as a shock, but the journey of the mind is still going, still battling chaos, still striving to ascend to the next stage of thinking.

The Journey Of The Mind Is Still Going

The minds in a given stage eventually reach the limit of what they can adapt to. Thinking hits a ceiling, and the minds in one stage just can’t deal with any new forms of chaos unless they learn to coordinate their activity. In other words, to ascend to a new stage of thinking, the minds in the old stage need to figure out how to connect and collaborate with one another.

Connect, Collaborate, Coordinate

Our experience of experience itself has long been the greatest mystery in the mind sciences. How can the physical activity of tiny, gooey cells in our cranium produce our wondrous experience of joy, and pain, and recognizing our friends, and understanding the meaning of the words that we are reading or listening to?But what matters even more than the details of how physical activity in our brain gets converted into the intangible banquet of awareness is what this explanation can do for us. How can knowing how consciousness works help our lives?

How did point-thinking minds learn to think about patterns? By teaming up. Each pattern-thinking mind is a community of point-thinking minds. Each neuron is a self-contained point-thinking mind. It takes a whole network of interconnected neurons—of interconnected point-thinking minds—to think about patterns.In turn, to think about objects, networks of neurons had to learn to communicate with one another. Networks learned to communicate using mental representations. It takes a community of interconnected networks exchanging representations with one another to think about objects.

Communities Of Minds

One of the most salient lessons from the journey of the mind is this: if we want to get smarter, we must embrace diversity. To explain why this is so, we must first understand another crucial concept. There have been four distinct stages of thinking on Earth—four distinct stages of minds.

There Have Been 4 Stages Of Minds

Thus, the three-billion-year journey of the mind imparts a very important lesson about the cosmic role of minds connecting with other minds. The only way for minds to ascend to new stages of intelligence, resilience, and awareness is by showing compassion for one another, freely sharing ideas, knowledge, and resources with one another, and accepting one another’s individuality.

Individuality And Mutuality

But the journey of the mind makes clear that humankind will only rise to a new stage of collective awareness if each of us prioritizes a few key behaviors: First, define your own unique purpose. Second, embrace diversity. Third, respect individuality. Fourth, expand your own sense of self by seeking out rich, complex, and nurturing superminds. Finally, and most importantly, show compassion, respect, and tolerance toward others.

What The Journey Of The Mind Makes Clear

The dynamics of language is binding one mind to another, enabling two persons to share awareness of the same ideas at the same time. This mind-to-mind exchange of ideas through language is how the human supermind thinks.So here’s the secret to the self: the self is formed out of the physical interaction of the dynamics of language and the dynamics of consciousness. It is the dance of language, which operates between minds, and consciousness, which operates inside our mind, that produces our uniquely human experience of, “I am aware of being me!”

Inside The Mind And Between Minds

The journey of the mind—so far—is the chronicle of purpose winning ever-more daunting battles with chaos. Minds defeat chaos by ascending to new stages of intelligence, autonomy, and awareness. Each new stage of thinking in the universe masters a broader scope of physical reality than the stage before. This makes it clear that human beings are not the ultimate destination of the journey of the mind at all.
