Science and Humanity

We have officially transitioned backwards as a species into an era of personal belief over facts, of emotion over intellect, of blind trust over earned authority.

We have striven to become significantly more fallible by sitting at the camp fire exchanging stories, choosing to first believe and then explore, a honeycomb of fictional realities.

Our little rock doesn't stand still. It moves at thousands of kilometres an hour around the sun, while rotating constantly on its own axis, with gravity pulling eternally—and yet some very clever people place explosives in a cylinder and fire it upwards, breaking free of our planet and then moving at thirty times the speed of sound to another celestial body which is also rotating around the sun on its own axis.

They aim the rocket at an empty point in space, knowing that the other planet will arrive at the exact moment the rocket does.

We can do all of that, and do it safely and reliably, not because of faith or emotion, not because of belief or trust. The numbers tell them it will be there, every time, to the second.

Science and mathematics do not care about your feelings or your complex personal belief structures. They do not worry about offending people or massaging ones’ scruples. It simply and succinctly solves a physical or theoretical problem as efficiently as possible.

Mathematics is the universal language. Unchanging and uncompromised.

But emotion and belief and trust are the language of mankind, it's what makes us human, a most endearing quality that allows love and hate, care and neglect, laughter and crying, and great triumph and cruelty.

The great works of Shakespeare and Tolkien and King and Koontz could simply not be written in the language of maths. They require a suspension of disbelief and an emotional core.

Because human behaviour hardly ever adds up.

But our strength is our weakness, and it's the exploitation of these analogue traits which has led us to place a greater importance on our beliefs than the facts.

More than ever, nefarious actors are taking the political, religious or social stage, and asking you to forget the truth, ignore the facts, trample the math, destroy the science and just believe them.

Trust them implicitly. Don't over-think, don't look too deeply, don't add it up or use common sense to interrogate the facts. Just trust them.

And so we now live in an age where conspiracy theoriests can mobilise an army, televangelists can ask their congregation for another eight hundred million to buy another jet, politicians can command more loyalty the more they lie and cheat and thieve, and Finding Bigfoot can enter a twelfth season without ever finding Bigfoot.

It's not necessary to destroy your humanity in order to defeat these exploitative forces trying to cajole you into believing nonsense. You don't have to stop your suspension of disbelief, or temper your emotion, or stop loving the ones you love.

You just need to compartmentalise or segment various types of knowledge and activity, and treat each one a little differently.

When you read Shakespeare or watch a romantic comedy or praise your God or watch your football team, let it all out, go to town, laugh and weep and give it your best.

But don't ever give a person the keys to your soul or your belief structure. Don't allow a politician to get you worked up. Don't let your guard down when you need to keep your wits.

Know when to use the language of people or the language of maths and science. Become fully bilingual and know when to change between the two.

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 distinguishes 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 believe in the fundamental value of all life. In turn, reason and observable evidence may lead to share 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.

How Life Has Value, Even Absent Overarching Purpose

Wherein lies value?

Posted by Keith Tidman

Among the most-common questions from philosophy is, ‘What is the purpose of life?’ After all, as Plato pithily said, humans are ‘beings in search of meaning’. But what might be the real reason for the question about the purpose of life? I suggest that what fundamentally lurks behind this age-old head-scratcher is an alternative query: Might not life still have value, even if there is no sublimely overarching purpose? So, instead, let’s start with ‘purpose’ and only then work our way to ‘value’.

Is an individual's existence best understood scientifically — more particularly, in biological terms? The purpose of biological life, in strictly scientific terms, might be reduced to survival and passing along genes — to propagate, for continuation of the familial line and (largely unconsciously) the species. More broadly, scientists have typically steered clear of deducing ‘higher purpose’ and are more comfortable restricting themselves to explanations of empirically, rationally grounded physical models — however inspiring those peeks into presumed reality may be — that relate to the ‘what’ and ‘how’ of existence. The list is familiar:

• the heliocentric construct of Copernicus and the mechanistic universes of René Descartes and Isaac Newton
• the Darwinian theories of evolution and natural selection
• the laws of thermodynamics and the theory of general relativity of Albert Einstein 
• the quantum mechanics of Niels Bohr, Max Planck, Werner Heisenberg, and Erwin Schrödinger. 

But grand as these theories are, they still don’t provide us with purpose.

Rather, such theories focus on better understanding the emergence and evolution of the cosmos and humankind, in all their wonder and complexity. The (not uncommonly murky) initial conditions and necessary parameters to make intelligent life possible add a challenge to relying on conclusions from the models. As to this point about believability and deductions drawn, David Hume weighed in during the 18th century, advising,

             ‘A wise man proportions his belief to the evidence’.

Meanwhile, modern physics doesn’t yet rule in or rule out some transcendent, otherworldly dimension of the universe — disproof is always tough, as we know, and thus the problem is perhaps unanswerable — but the physical–spiritual dualism implied by such an ethereal dimension is extraordinarily questionable. Yet one cannot deduce meaning or purpose, exceptional or ordinary, simply from mere wonder and complexity; the latter are not enough. Suggested social science insights — about such things as interactions among people, examining behaviours and means to optimise social constructs — arguably add only a pixel here and a pixel there to the larger picture of life’s quintessential meaning.

Religious belief — from the perspectives of revelation, enlightenment, and doctrine — is an obvious place to turn to next in this discussion. Theists start with a conviciton that God exists — and conclude that it was God who therefore planted the human species amidst the rest of His creation of the vast universe. In this way, God grants humankind an exalted overarching purpose. In no-nonsense fashion, the 17th-century Dutch philosopher Baruch Spinoza took the point to another declarative level, writing:

‘Whatever is, is in God, and without God nothing can be, or be conceived’. 

This kind of presumed God-given plan or purpose seems to instill in humankind an inspirational level of exceptionalism. This exceptionalism in turn leads human beings toward such grand purposes as undiminished love toward and worship of God, fruitful procreation, and dominion over the Earth (with all the environmental repercussions of that dominion), among other things. These purposes include an implied contract of adding value to the world, within one’s abilities, as prescribed by religious tenets.

One takeaway may be a comfortable feeling that humankind, and each member of our species, has meaning — and, in a soul-based model, a roadmap for redemption, perhaps to an eternal afterlife. As to that, in the mid-20th century, Jean-Paul Sartre wrote in characteristically unsparing fashion:

‘Life has no meaning the moment you lose the illusion of being eternal’. 

Universes constructed around a belief in God, thereby, attempt to allay the dread of mortality and the terror of dying and of death. Yet, even where God is the prime mover of everything, is it unreasonable to conceive of humankind as perhaps still lacking any lofty purpose, after all? Might, for example, humankind share the universe with other brainy species on our own planet — or even much brainier ones cosmically farther flung?

Because if humankind has no majestically overarching purpose — or put another way, even if existentially it might not materially matter to the cosmos if the human species happened to tip into extinction — we can, crucially, still have value. Ultimately value, not exceptionalism or eternity, is what matters. There’s an important difference between ‘purpose’ — an exalted reason that soars orders of magnitude above ordinary explanations of why we’re riding the rollercoaster of creation — and ‘value’, which for an individual might only need a benevolent role in continuously improving the lot of humankind, or perhaps other animals and the ecosphere. It may come through empathically good acts without the expectation of any manner of reward. Socrates hewed close to those principles, succinctly pointing out,

            ‘Not life, but a good life, is to be chiefly valued’.

Value, then, is anchored to our serving as playwrights scribbling, if you will, on pieces of paper how our individual, familial, community, and global destiny unfolds into the future. And what the quality of that future is, writ large. At minimum, we have value based on humanistic grounds: people striving for natural, reciprocal connections, to achieve hope and a range of benefits — the well-being of all — and disposing of conceits to instead embrace our interdependence in order not only to survive but, better, to thrive. This defines the intrinsic nature of ‘value’; and perhaps it is to this that we owe our humanity.
