‘What Are We?’ “Self-reflective Consciousness, Cooperation, and the Agents of Our Future Evolution”

Cueva de las Manos, Río Pinturas

Posted by John Hands 

‘What are we?’ This is arguably the fundamental philosophical question. Indeed, ‘What are we?’ along with ‘Where do we come from?’ and ‘Why do we exist?’ are questions that humans have been asking for at least 25,000 years. During all of this time we have sought answers from the supernatural. About 3,000 years ago, however, we began to seek answers through philosophical reasoning and insight. Then, around 150 years ago, we began to seek answers through science: through systematic, preferably measurable, observation or experiment. 

As a science graduate and former tutor in physics for Britain's ‘Open University*’, I wanted to find out what answers science currently gives. But I couldn’t find any book that did so. There are two reasons for this.

  • First, the exponential increase in empirical data generated by rapid developments in technology had resulted in the branching of science into increasingly narrow, specialized fields. I wanted to step back from the focus of one leaf on one branch and see what the whole evolutionary tree shows us. 
  • Second, most science books advocate a particular theory, and often present it as fact. But scientific explanations change as new data is obtained and new thinking develops. 

And so I decided to write ‘the book that hadn’t been written’: an impartial evaluation of the current theories that explain how we evolved, not just from the first life on Earth, but where that came from, right back to the primordial matter and energy at the beginning of the universe of which we ultimately consist. I called it COSMOSAPIENS Human Evolution from the Origin of the Universe* and in the event it took more than 10 years to research and write. What’s more, the conclusions I reached surprised me. I had assumed that the Big Bang was well-established science. But the more I investigated the more I discovered that the Big Bang Theory had been contradicted by observational evidence stretching back 60 years. Cosmologists had continually changed this theory as more sophisticated observations and experiments produced ever more contradictions with the theory.

The latest theory is called the Concordance Model. It might more accurately be described as ‘The Inflationary-before-or-after-the-Hot Big Bang-unknown-27% Dark Matter-unknown-68% Dark Energy model’. Its central axiom, that the universe inflated at a trillion trillion trillion times the speed of light in a trillion trillion trillionth of a second is untestable. Hence it is not scientific.

The problem arises because these cosmological theories are mathematical models. They are simplified solutions of Einstein’s field equations of general relativity applied to the universe. They are based on assumptions that the latest observations show to be invalid. That’s one surprising conclusion I found. 

Another surprise came when I examined the orthodox theory for the last 65 years in the UK and the USA of how and why life on Earth evolved into so many different species. It is known as NeoDarwinism, and was popularised by Richard Dawkins in his bestselling book, The Selfish Gene, where it says that biological evolution is caused by genes selfishly competing with each other to survive and replicate.

NeoDarwinism is based on the fallacy of ascribing intention to an acid, deoxyribonucleic acid, of which genes are composed. Dawkins admits that this language is sloppy and says he could express it in scientific terms. But I’ve read the book twice and he never does manage to do this. Moreover, the theory is contradicted by substantial behavioural, genetic, and genomic evidence. When confronted by such, instead of modifying the theory to take account of the evidence, as a scientist should do, Dawkins lamely says “genes must have misfired”. 

The fact is, he couldn’t modify the theory because the evidence shows that Darwinian competition causes not the evolution of species but the destruction of species. It is cooperation, not competition, that has caused the evolution of successively more complex species.

Today, most biologists assert that we differ only in degree from other animals. I think that this too is wrong. What marked our emergence as a distinct species some 25,000 years ago wasn’t the size or shape of our skulls, or that we walked upright, or that we lacked bodily hair, or the genes we possess. These are differences in degree from other animals. What made us unique was reflective consciousness.

Consciousness is a characteristic of a living thing as distinct from an inanimate thing like a rock. It is possessed in rudimentary form by the simplest species like bacteria. In the evolutionary lineage leading to humans, consciousness increased with increasing neural complexity and centration in the brain until, with humans, it became conscious of itself. We are the only species that not only knows but also knows that it knows. We reflect on ourselves and our place in the cosmos. We ask questions like: What are we? Where did we come from? Why do we exist? 

This self-reflective consciousness has transformed existing abilities and generated new ones. It has transformed comprehension, learning, invention, and communication, which all other animals have in varying degrees. It has generated new abilities, like imagination, insight, abstraction, written language, belief, and morality that no other animal has. Its possession marks a difference in kind, not merely degree, from other animals, just as there is a difference in kind between inanimate matter, like a rock, and living things, like bacteria and animals. 

Moreover, Homo sapiens is the only known species that is still evolving. Our evolution is not morphological—physical characteristics—or genetic, but noetic, meaning ‘relating to mental activity’. It is an evolution of the mind, and has been occurring in three overlapping phases: primeval, philosophical, and scientific. 

Primeval thinking was dominated by the foreknowledge of death and the need to survive. Accordingly, imagination gave rise to superstition, which is a belief that usually arises from a lack of understanding of natural phenomena or fear of the unknown. 

It is evidenced by legends and myths, the beliefs in animism, totemism, and ancestor worship of hunter-gatherers, to polytheism in city-states in which the pantheon of gods reflected the social hierarchy of their societies, and finally to a monotheism in which other gods were demoted to angels or subsumed into one God, reflecting the absolute power of king or emperor. 

The instinct for competition and aggression, which had been ingrained over millions of years of prehuman ancestry, remained a powerful characteristic of humans, interacting with, and dominating, reflective consciousness. 

The second phase of reflective consciousness, philosophical thinking, emerged roughly 1500 to 500 BCE. It was characterised by humans going beyond superstition to use reasoning and insight, often after disciplined meditation, to answer questions. In all cultures it produced the ethical view that we should treat all others, including our enemies, as ourselves. This ran counter to the predominant instinct of aggression and competition. 

The third phase, scientific thinking, gradually emerged from natural philosophy around 1600 CE. It branched into the physical sciences, the life sciences, and medical sciences. 

Physics, the fundamental science, then started to converge, rapidly so over the last 65 years, towards a single theory that describes all the interactions between all forms of matter. According to this view, all physical phenomena are lower energy manifestations of a single energy at the beginning of the universe. This is similar in very many respects to the insight of philosophers of all cultures that there is an underlying energy in the cosmos that gives rise to all matter and energy. 

During this period, reflective consciousness has produced an increasing convergence of humankind. The development of technology has led to globalisation, both physically and electronically, in trade, science, education, politics (United Nations), and altruistic activities such as UNICEF and Médecins Sans Frontières. It has also produced a ‘complexification’ of human societies, a reduction in aggression, an increase in cooperation, and the ability to determine humankind’s future. 

This whole process of human evolution has been accelerating. Primeval thinking emerges roughly 25,000 years ago, philosophical thinking emerges about 3,000 years ago, scientific thinking emerges some 400 years ago, while convergent thinking begins barely 65 years ago. 

I think that when we examine the evidence of our evolution from primordial matter and energy at the beginning of the universe, we see a consistent pattern. This shows that we humans are the unfinished product of an accelerating cosmic evolutionary process characterised by cooperation, increasing complexity and convergence, and that – uniquely as far we know – we are the self-reflective agents of our future evolution.

Humanism: Intersections of Morality and the Human Condition

Kant urged that we ‘treat people as ends in themselves, never as means to an end’
Posted by Keith Tidman

At its foundation, humanism’s aim is to empower people through conviction in the philosophical bedrock of self-determination and people’s capacity to flourish — to arrive at an understanding of truth and to shape their own lives through reason, empiricism, vision, reflection, observation, and human-centric values. Humanism casts a wide net philosophically — ethically, metaphysically, sociologically, politically, and otherwise — for the purpose of doing what’s upright in the context of individual and community dignity and worth.

Humanism provides social mores, guiding moral behaviour. The umbrella aspiration is unconditional: to improve the human condition in the present, while endowing future generations with progressively better conditions. The prominence of the word ‘flourishing’ is more than just rhetoric. In placing people at the heart of affairs, humanism stresses the importance of the individual living both free and accountable — to hand off a better world. In this endeavour, the ideal is to live unbound by undemocratic doctrine, instead prospering collaboratively with fellow citizens and communities. Immanuel Kant underscored this humanistic respect for fellow citizens, urging quite simply, in Groundwork of the Metaphysics of Morality, that we ‘treat people as ends in themselves, never as means to an end’. 

The history of humanistic thinking is not attributed to any single proto-humanist. Nor has it been confined to any single place or time. Rather, humanist beliefs trace a path through the ages, being reshaped along the way. Among the instrumental contributors were Gautama Buddha in ancient India; Lao Tzu and Confucius in ancient China; Thales, Epicurus, Pericles, Democritus, and Thucydides in ancient Greece; Lucretius and Cicero in ancient Rome; Francesco Petrarch, Sir Thomas More, Michel de Montaigne, and François Rabelais during the Renaissance; and Daniel Dennett, John Dewey, A.J. Ayer, A.C. Grayling, Bertrand Russell, and John Dewey among the modern humanist-leaning philosophers. (Dewey contributed, in the early 1930s, to drafting the original Humanist Manifest.) The point being that the story of humanism is one of ubiquity and variety; if you’re a humanist, you’re in good company. The English philosopher A.J. Ayer, in The Humanist Outlook, aptly captured the philosophy’s human-centric perspective:

‘The only possible basis for a sound morality is mutual tolerance and respect; tolerance of one another’s customs and opinions; respect for one another’s rights and feelings; awareness of one another’s needs’.

For humanists, moral decisions and deeds do not require a supernatural, transcendent being. To the contrary: the almost-universal tendency to anthropomorphise God, to attribute human characteristics to God, is an expedient to help make God relatable and familiar that can, at the same time, prove disquieting to some people. Rather, humanists’ belief is generally that any god, no matter how intense one’s faith, can only ever be an unknowable abstraction. To that point, the opinion of the eighteenth-century Scottish philosopher David Hume — ‘A wise man proportions his belief to the evidence’ — goes to the heart of humanists’ rationalist philosophy regarding faith. Yet, theism and humanism can coexist; they do not necessarily cancel each other out. Adherents of humanism have been religious, agnostic, and atheist — though it’s true that secular humanism, as a subspecies of humanism, rejects a religious basis for human morality.

For humanists there is typically no expectation of after-life rewards and punishments, mysteries associated with metaphorical teachings, or inspirational exhortations by evangelising trailblazers. There need be no ‘ghost in the machine’, to borrow an expression from British philosopher Gilbert Ryle: no invisible hand guiding the laws of nature, or making exceptions to nature’s axioms simply to make ‘miracles’ possible, or swaying human choices, or leaning on so-called revelations and mysticism, or bending the arc of human history. Rather, rationality, naturalism, and empiricism serve as the drivers of moral behaviour, individually and societally. The pre-Socratic philosopher Protagoras summed up these ideas about the challenges of knowing the supernatural:

‘About the gods, I’m unable to know whether they exist or do not exist, nor what they are like in form: for there are things that hinder sure knowledge — the obscurity of the subject and the shortness of human life’.

The critical thinking that’s fundamental to pro-social humanism thus moves the needle from an abstraction to the concreteness of natural and social science. And the handwringing over issues of theodicy no longer matters; evil simply happens naturally and unavoidably, in the course of everyday events. In that light, human nature is recognised not to be perfectible, but nonetheless can be burnished by the influences of culture, such as education, thoughtful policymaking, and exemplification of right behaviour. This model assumes a benign form of human centrism. ‘Benign’ because the model rejects doctrinaire ideology, instead acknowledging that while there may be some universal goods cutting across societies, moral decision-making takes account of the often-unique values of diverse cultures.

A quality that disinguishes humanity is its persistence in bettering the lot of people. Enabling people to live more fully — from the material to the cultural and spiritual — is the manner in which secular humanism embraces its moral obligation: obligation of the individual to family, community, nation, and globe. These interested parties must operate with a like-minded philosophical belief in the fundamental value of all life. In turn, reason and observable evidence may lead to shared moral goods, as well as progress on the material and immaterial sides of life’s ledger.

Humanism acknowledges the sanctification of life, instilling moral worthiness. That sanctification propels human behaviour and endeavour: from progressiveness to altruism, a global outlook, critical thinking, and inclusiveness. Humanism aspires to the greater good of humanity through the dovetailing of various goods: ranging across governance, institutions, justice, philosophical tenets, science, cultural traditions, mores, and teachings. Collectively, these make social order, from small communities to nations, possible. The naturalist Charles Darwin addressed an overarching point about this social order:

‘As man advances in civilisation, and small tribes are united into larger communities, the simplest reason would tell each individual that he ought to extend his social instincts and sympathies to all the members of the same nation, though personally unknown to him’.

Within humanism, systemic challenges regarding morality present themselves: what people can know about definitions of morality; how language bears on that discussion; the value of benefits derived from decisions, policies, and deeds; and, thornily, deciding what actually benefits humanity. There is no taxonomy of all possible goods, for handy reference; we’re left to figure it out. There is no single, unconditional moral code, good for everyone, in every circumstance, for all time. There is only a limited ability to measure the benefits of alternative actions. And there are degrees of confidence and uncertainty in the ‘truth-value’ of moral propositions.

Humanism empowers people not only to help avoid bad results, but to strive for the greatest amount of good for the greatest number of people — a utilitarian metric, based on the consequences of actions, famously espoused by the eighteenth-century philosopher Jeremy Bentham and nineteenth-century philosopher John Stuart Mill, among others. It empowers society to tame conflicting self-interests. It systematises the development of right and wrong in the light of intent, all the while imagining the ideal human condition, albeit absent the intrusion of dogma.

Agency in promoting the ‘flourishing’ of humankind, within this humanist backdrop, is shared. People’s search for truth through natural means, to advance everyone’s best interest, is preeminent. Self-realisation is the central tenet. Faith and myth are insufficient. As modern humanism proclaims, this is less a doctrine than a ‘life stance’. Social order, forged on the anvil of humanism and its core belief in being wholly responsible for our own choices and lives, through rational measures, is the product of that shared agency.
