Future Stories

by David Christian

Future Stories: What’s Next? offers a multidisciplinary exploration of how we make choices about the future. David Christian draws from biology, philosophy, and cosmology to illuminate humanity''s critical role in shaping a sustainable future amidst uncertainty and change.

The Human Quest to Know the Future

How can you anticipate what comes next when the future is inherently uncertain? Historian David Christian argues that the ability to imagine, predict, and shape the future is one of the most distinctive human traits, but it is also a biological inheritance from life itself. In Future Stories, he explores how life—from microbes to modern civilizations—has developed strategies to manage uncertainty, interpret time, and act with purpose. The book’s core claim is that all living systems are future-oriented, but humans have expanded this capacity through language, science, and collective learning.

The story unfolds in a sweeping arc: it begins with metaphysical debates about time’s nature, then moves through biological evolution and cultural history to modern scientific forecasting, planetary futures, and finally cosmic time. Across these scales, Christian’s central question remains constant: how do you think about what hasn’t happened yet in a way that improves your chances of thriving?

Time’s Dual Metaphors

Christian starts with two metaphors—time as a river (A-series) and as a map (B-series). The river picture captures human experience: you drift forward into an unknown future, where possibilities collapse into actualities as events unfold. The map perspective, by contrast, is the physicist’s: past, present, and future coexist like locations on a chart. You live in the river but sometimes need the map to understand constraints such as causality and entropy. Balancing these views protects you from either fatalism or the illusion of complete control.

Christian reminds you that prediction always operates between these two extremes—flow and fixity. Science can define causal limits (Einstein’s light cones, Judea Pearl’s causal diagrams) but can never eliminate uncertainty entirely, thanks to Gödel’s incompleteness, quantum indeterminacy, and chaos theory. This framing sets up his broader thesis: good future thinking combines metaphysical humility with practical method.

From Life to Conscious Intelligence

Christian’s next move is evolutionary. All organisms, he argues, act as imperfect prediction engines. Every cell or creature follows a three-step kit: set goals (a Utopia like food or safety), hunt trends through sensing and memory, and act while updating based on results. Even an E. coli bacterium uses this algorithm—it senses nutrient gradients, adjusts its motion ("tumble and swim"), and modifies behavior based on chemical feedback. That cellular model becomes a microcosm of all forecasting: goal‑orientation, evidence gathering, and Bayesian updating.

As complexity grows, coordination becomes vital. Plants anticipate seasonal change through chromatin ‘memories’; animals centralize forecasting in nervous systems. In brains, neurons store patterns, make predictions, and simulate futures—what Patricia Churchland calls the brain’s defining feature: anticipation. These biological stories show a deep continuity between behavior and foresight: life survives by managing uncertainty and learning from feedback loops.

Humans and Collective Futures

Human beings took future thinking to a new level. Enlarged frontal cortices support planning over long horizons, and language allows complex futures to be shared, remembered, and refined. Through cumulative culture—knowledge building on knowledge—humans became global-scale forecasters. The invention of writing, calendars, and science transformed private hunches into collective institutions of prediction. As a result, the future became a civic project as much as a personal one.

Christian situates this transformation historically: from agrarian divination and royal oracles that stabilized empires, to the scientific revolution and its mechanistic worldview, to modern probabilistic models and computational forecasting. Each step represents both a gain in predictive precision and a shift in responsibility. When you interpret omens or run data models, you are trying to make an opaque future more legible for action.

The Modern Turn: Science and Disenchantment

Modernity’s distinctive move was to replace gods and spirits with causes and probabilities. Newton’s mechanics, Boyle’s experiments, and Pascal’s mathematics turned fortune into measurable risk. Yet Christian underscores that not all processes fit deterministic molds: social and biological systems remain partly unpredictable because they involve purposeful agents. The challenge, therefore, is to mix the rigor of science with humility before contingency—a stance that underlies both statistical forecasting and moral responsibility.

Futures of Planet and Cosmos

The book’s timeline finally expands from the near future to cosmic horizons. Christian explores today’s crossroads—between collapse, downsizing, sustainability, and techno-optimistic growth—before imagining “middle futures” where renewable energy, AI, and biotechnology reshape what it means to be human. He ends with remote futures: a cooling Earth, a dying Sun, and an expanding universe. Against that vast backdrop, human action now acquires cosmic significance: tiny in scale, immense in consequence.

Key takeaway

You are a biological forecaster embedded in a cosmic story. Effective future thinking demands both the river’s urgency (act ethically in real time) and the map’s perspective (see the structural limits and large-scale patterns). From cells to civilizations, Christian reveals that the art of anticipating tomorrow is ultimately about survival, stewardship, and imagination.


Time, Causality, and the Shape of Prediction

Christian begins by mapping the philosophical terrain of time. The A-series, or “time as river,” captures your lived experience of flow—past, present, and future as fundamentally different. The B-series, or “time as map,” captures the physicist’s block universe, where all events coexist. Both frames coexist in your thinking and shape how you interpret causality and freedom.

Causation and Determinism

If time were fully mapped, human choice would seem illusory. Pierre-Simon Laplace’s demon embodies that fear: a cosmic intelligence could calculate everything if it knew every atom’s position and force. But Christian surveys the 20th-century revolt: Gödel’s theorems, Turing’s computability limits, Heisenberg’s uncertainty, and chaos theory (the butterfly effect) all show that perfect prediction is impossible even in a lawful universe.

Physics introduces constraint more than prophecy. Within Einstein’s spacetime, light cones define where influence can travel and preserve local causation. Those geometric limits anchor both humility and possibility: you can act within your cone but not outside it. Judea Pearl’s modern causal models reframe this insight as practical: limited actors can still model “what if” interventions that reshape local futures.

Entropy and Directionality

Even if the universe’s map is static, it isn’t symmetrical. The second law of thermodynamics gives time an arrow: entropy increases. This directionality is why you remember the past, not the future, and why evolution, decay, and history all unfold irreversibly. Understanding that asymmetry links human responsibility to physical law—you cannot undo actions freely, but you can choose which low-entropy futures to pursue.

In essence

You live between flow and structure. The “river” gives moral urgency—choices matter because the future isn’t written. The “map” gives systemic clarity—causes have boundaries and ripple effects. Effective forecasting, and ethical living, require both metaphors working together.


Biology’s Universal Forecasting Kit

Christian calls prediction one of life’s universal features. Every organism, from bacteria to humans, carries out future management with three steps: (1) set goals, (2) sense trends, (3) act and update. This biological “kit” is the foundation of all anticipation.

Goals and Utopias

All living systems have intrinsic goals—survival and reproduction—but each species defines its Utopia differently. For microbes, it’s nutrient-rich environments; for trees, access to light; for humans, security and meaning. These preferred futures orient every action. (Christian borrows Utopia from Thomas More to stress that all living systems imagine “better states.”)

Trend Hunting and Memory

Organisms track change. Even single cells possess molecular “memories”—shape shifts lasting milliseconds that encode direction. In higher species, memories extend over minutes, years, or generations. Plants record cold spells through epigenetic changes (vernalization); neurons in animals record experiences to anticipate hazards or rewards. Evolution tuned memory for prediction, not nostalgia.

Action and Updating

Once goals and trends align, organisms act—tentatively, probabilistically. They update as new information arrives, effectively performing Bayesian learning. You do the same when you test a new habit or investment. This adaptability, not perfect foresight, keeps life resilient. Christian notes this principle scales: ecological systems and economies alike thrive through feedback and recalibration.

Universal lesson

Forecasting is not uniquely human—it is life’s defining algorithm. Survival arises from good-enough sensing, right-sized risk, and timely correction rather than omniscience.


Brains, Language, and Collective Learning

As evolution advanced, coordination among cells formed nervous systems and eventually brains—organs built for predictive modeling. Christian traces how these models scaled up in humans and combined with language to create collective foresight unmatched in nature.

Predictive Brains

Nervous systems turn sensory inputs into expectations. Neurons fire not reactively but anticipatorily, predicting the next signal. Eric Kandel’s work on sea slugs (Aplysia) revealed how synaptic changes encode learning; Daniel Kahneman’s “fast and slow” systems correspond to quick heuristics and deliberate planning. Your brain continually runs simulations to minimize surprise—a mechanism echoed in Karl Friston’s “free energy principle.”

Language and Collective Forecasting

Language multiplies foresight by linking brains together. Through words and stories, you share hypotheses about what might happen and coordinate responses. Vygotsky called this internalized dialogue the foundation of thought itself. Across generations, such shared foresight accumulates—Christian calls it collective learning. Cultural evolution researcher Alex Mesoudi shows how this process drives technological progress by preserving and refining knowledge rather than restarting from zero each generation.

Acceleration and Risk

Language accelerated change. Agriculture, trade, and science built feedback loops of innovation that now reshape the planet. Didier Sornette’s “dragon-king” idea captures this: humans are powerful yet dangerous because feedback amplifies our inventions. Christian argues that foresight has become a moral responsibility; your choices scale to the whole biosphere—a condition Alfred North Whitehead foresaw when he called modernity an age of “novelty within a lifetime.”

Takeaway

Brains anticipate; language shares anticipation. Together they turn foresight into civilization, with both power and peril attached.


From Divination to Science

Christian frames history as an evolution of forecasting systems. In agrarian civilizations, divination rituals managed uncertainty through symbolism and performance. In the modern era, science and statistics replaced spirits with causes and probabilities—but the social functions of prediction remained remarkably similar.

Divination as Social Technology

Across Mesopotamia, Greece, China, and Africa, oracles translated uncertainty into action. The Oracle of Delphi guided Greek state policy; Chinese oracle bones merged cosmology with bureaucracy. Christian highlights divination’s pragmatic side: it wasn’t only about prophecy but also about legitimizing rule and coordinating large groups. Ritual drama—casting lots or interpreting omens—created a shared language for probability before probability existed formally.

The Disenchantment and the Scientific Mind

The scientific revolution secularized foresight. Torricelli’s barometer (1644) and Pascal’s mountain experiment (1648) exemplify the new logic: test, measure, predict. Newton’s and Boyle’s mechanical universe reframed miracles as mechanisms. Max Weber called this the “disenchantment of the world”: nature became calculable, and with that came interventionist power—from germ theory to meteorology.

Probability and the Birth of Statistics

Pascal, Bernoulli, and Laplace turned gambling math into scientific forecasting. The normal curve, standard deviations, and Bayesian updating arose to quantify probabilistic futures. Christian reminds you that statistics institutionalized ancient intuitions: collect data, count outcomes, and estimate risk. Today’s Monte Carlo methods and IPCC confidence intervals continue that tradition with digital precision.

Practical insight

What began as ritual has become rigorous modeling, but every era seeks the same reassurance: to make uncertain horizons manageable so societies can act together.


Computation, Globalization, and Modern Forecasting

With computation, forecasting entered a new epoch. Supercomputers, data streams, and systems modeling extended your predictive reach—but also revealed hard limits when human behavior intervenes. Christian contrasts domains of high predictability (physics, meteorology) with those of low predictability (politics, economics).

Models in Action

The 1972 Limits to Growth report used Forrester’s World3 model to simulate global interactions between population, resources, and pollution. Though often misunderstood as prophecy, World3’s purpose was diagnostic: to map feedback loops and stress-test policy choices. Mathematical models like these clarify interdependencies but depend on accurate data and political commitment.

Successes and Failures

Weather forecasting showcases modeling triumph: with satellites and supercomputers, reliable six-day outlooks are now routine. Economic forecasting, by contrast, struggles with agents who react to forecasts themselves—a recursive unpredictability. The lesson: models are guides for reasoning, not oracles.

A Globalized Temporal Web

Christian then widens the view. Global trade, social media, and synchronized clock time have woven humanity into a single temporal system. The Anthropocene—our geological imprint—forces global coordination: carbon cycles, pandemics, and markets all move on planetary timescales. With power over biospheric processes comes shared accountability.

Guiding principle

Invest in computation and data, but blend them with moral imagination and adaptive governance. The global clock ticks faster; foresight must be wiser.


Scenarios, Technology, and Cosmic Futures

Christian closes with nested futures—from the next century to the universe’s end. Using scenario thinking, he explores four near-term pathways (collapse, downsizing, sustainability, growth), medium-term technological transformations, and remote cosmic evolutions.

Four Pathways

Collapse depicts existential risks—nuclear war, pandemics, unaligned AI. Downsizing envisions enforced ecological restraint. Sustainability blends innovation with stewardship (UN Sustainable Development Goals). Growth bets on technology and markets to solve crises but risks overshooting planetary limits. These options are ethical as much as empirical: choice, not fate, determines trajectory.

Middle Futures

Looking a thousand years ahead, Christian imagines energy abundance through renewables and perhaps Kardashev-level civilizations harnessing planetary power. Nanotechnology could localize production; biotechnology and AI could redefine humanity. Transhumanism raises identity questions, while space migration could hedge species survival. Governance, equity, and moral foresight are essential to guide these powers safely.

Remote Horizons

Cosmically, the outlook spans billions of years: continents merge, the Sun reddens, galaxies collide, and entropy prevails. Humanity’s moment sits near the dawn of cosmic time, suggesting that if we survive our adolescence as a species, immense chapters lie ahead. The ultimate lesson: your near-term ethics shape distant universes of potential.

Perspective

Seen on cosmic scales, foresight is both humble and heroic. Acting wisely today may secure not just a civilization but life’s long future in the unfolding story of the universe.
