A public commitment

One hundred paths.

Catalyst is building a hundred paths over the next two years. This is the list.

The library is the product. Most learning apps are content marketplaces — the more, the better. Catalyst is the opposite: a small number of carefully curated paths, written by hand, that you can actually finish. A hundred feels like the right ceiling for two years of patient work. Far enough to keep the library growing for years before you run out; small enough that every path has to earn its place.

This page exists so the work is in the open. Anyone can see what's live, what's being written, and what's planned. If a path moves from Planned to In progress, you'll see it here first.

Philosophy

15 paths

The old questions, taken seriously. Schools, not soundbites.

  • Live
    A week with Marcus, Seneca, and Epictetus — the dichotomy of control, voluntary discomfort, memento mori.
  • In progress
    Three deep sessions with Plato, Russell, and de Botton on examining your assumptions and knowing the limits of what you know.
  • In progress
    Meditations, then Letters, then Discourses — fourteen days through the canonical Stoics, from most accessible to most demanding.
  • In progress
    Naval, Taleb, Frankl — three aphorists on the inner locus: judgment, antifragility, meaning under pressure.
  • Planned
    East meets West
    Meditations, Tao Te Ching, and the Striking Thoughts of Bruce Lee. Three traditions converging on the same suspicions about the self.
  • Planned
    Aristotle on friendship
    A patient reading of Books VIII and IX of the Nicomachean Ethics — the three kinds of friendship, why most adult friendships are the lesser two, and what to do about it.
  • Planned
    Spinoza in plain English
    A week inside the Ethics without the geometric scaffolding — necessity, joy, the absurdity of free will, and what Damasio thinks Spinoza got right.
  • Planned
    Existentialism for skeptics
    Sartre, Camus, Kierkegaard — read by someone who finds the word "existentialism" slightly embarrassing. Freedom, absurdity, the leap.
  • Planned
    How to read philosophy
    A short course in the moves: how to follow an argument, when to stop and re-read, how to tell a real disagreement from a vocabulary problem.
  • Planned
    Confucius and the Analects
    A patient first reading of the most influential book most Western readers have never opened. Ren, li, and the question of what it means to become someone.
  • Planned
    Modern Stoicism
    Ryan Holiday's Obstacle / Ego / Stillness trilogy. The same argument from three angles — adversity, ambition, peace.
  • Planned
    Hume and the limits of reason
    The Treatise made readable. Why induction is a problem, why is doesn't imply ought, and why the most modest philosopher in the canon is also the most disturbing.
  • Planned
    Mortality and meaning
    A Stoic-Existentialist crossover. Marcus and Camus on the same shelf — the brevity of life as raw material rather than threat.
  • Planned
    A short course in argument
    Logical form, common fallacies, and the higher art of charity. How to disagree with someone without misrepresenting them.
  • Planned
    Wittgenstein, slowly
    The Tractatus and the Investigations as two attempts at the same problem. Language games, family resemblances, what philosophy can and cannot dissolve.

Psychology

12 paths

How the mind actually works — the embodied, social, occasionally unreliable thing it is.

  • In progress
    Goleman, Burns, and Brown on the basics — thoughts are not facts, emotions are information, naming what you feel.
  • In progress
    Kahneman, Ariely, and Cialdini layered — two systems, choice architecture, social engineering. With honest replication-crisis caveats throughout.
  • In progress
    Van der Kolk, Walker, and Gottlieb — the embodied half of psychology. Trauma, sleep, the therapeutic relationship, with the books' real limits surfaced.
  • In progress
    Frankl, Tolle, and Manson — three temperaments on suffering. Measured, contemplative, irreverent, converging on the same argument.
  • Planned
    Why we mis-explain ourselves
    A patient tour through the introspection illusion. We do not have privileged access to our own motives — and what to do with that fact.
  • Planned
    A short history of attention
    From William James to Cal Newport. What the word means, what it costs, and what the slot machine in your pocket is doing to it.
  • Planned
    Behavioural economics, seriously
    For the curious-but-busy reader. Loss aversion, framing, mental accounting — and a clear-eyed look at which findings replicated and which didn't.
  • Planned
    The science of mood
    Light, sleep, movement, food, social contact. The boring, well-evidenced inputs to a stable inner weather — and how few people actually run them.
  • Planned
    Therapy without jargon
    A short course on what the major modalities (CBT, IFS, psychodynamic, ACT) actually do — and how a non-clinician should think about which one might fit a friend.
  • Planned
    The inner critic
    Where the voice comes from, why it sounds so confident, and the practical moves that loosen its hold without trying to argue with it.
  • Planned
    Memory, and what it is for
    Endel Tulving onward. Why memory is a tool for the future, not a record of the past — and what that means for how we revise the stories of our lives.
  • Planned
    The lonely century
    Noreena Hertz, Robert Putnam, the surgeon-general's advisory. Why loneliness is a public-health problem, and what reading the data does to the self-help framing.

History & big ideas

12 paths

The long arc. The kind of history that changes how you read the news.

  • Planned
    History, an introduction
    Three sessions on what history is for — not the names and dates, but the discipline of reading the past as a foreign country with its own logic.
  • Planned
    A short history of the book
    Scroll to codex to print to ebook. How the physical object shaped what could be thought, and what we lose each time the form changes.
  • Planned
    The Enlightenment, contested
    Pinker on the case for it, Gray on the case against, Israel on what actually happened. A patient three-way argument about the inheritance.
  • Planned
    Sapiens, then the pushback
    Harari's bestseller read alongside Graeber and Wengrow's Dawn of Everything. The big story, and the one that complicates it.
  • Planned
    The Industrial Revolution, up close
    Why it happened in Britain, why it happened when it did, and why economic historians still argue about it. Mokyr, Allen, McCloskey.
  • Planned
    A short history of money
    Coinage, paper, the gold standard, fiat, crypto. Felix Martin, David Graeber, and the question of what money has always actually been.
  • Planned
    The twentieth century in five
    Five hinge moments — Sarajevo, Versailles, 1945, the Cuban Missile Crisis, 1989 — read for the shape of the century rather than the chronology.
  • Planned
    The Cold War, without the swagger
    Gaddis as the foundation, Westad for the global view. The forty years that made the world we still live in, told without triumphalism.
  • Planned
    How empires end
    Gibbon's Rome, Ferguson's modern empires, the case studies most pundits don't actually know. The shapes a decline can take.
  • Planned
    The history of capitalism
    From Smith to Polanyi to Piketty. Three angles on how markets came to organise modern life — and on the things they cannot price.
  • Planned
    Why nations succeed
    Acemoglu and Robinson, with the counterweights — geography, culture, contingency. A patient argument about institutions.
  • Planned
    The slow Reformation
    MacCulloch's account, MacCulloch's caveats. How a quarrel about indulgences became three centuries of remaking Europe — and what it means that printing made it possible.

Habits & discipline

9 paths

The unglamorous middle layer between intention and outcome.

  • In progress
    Seven foundational moves from Duhigg, Fogg, and Clear. Tiny anchors, the celebration, the never-miss-twice rule.
  • In progress
    Duhigg to Fogg to Clear. The habit loop, then design, then identity — three layers of the same problem, sequenced.
  • In progress
    Twenty-one days with Duckworth, Dweck, and Newport. The length of the path is itself the lesson.
  • Planned

    The neuroscience layer underneath the popular books. Basal ganglia, dopamine prediction error, the difference between learning a habit and breaking one.
  • Planned
    Deep work, in practice
    Cal Newport's argument, then a week of trying to actually live it. The four philosophies of depth, the shutdown ritual, the empty calendar.
  • Planned

    Newport's third book, in the company of Pieper, Odell, and Burkeman. Why fewer things, at a natural pace, with obsessive quality.
  • Planned
    The four thousand weeks
    Burkeman's argument, in full. Finitude as the precondition for taking your life seriously — and why most productivity advice is a denial mechanism.

    The case against motivation
    Why feeling like it is the wrong target. A week with the people who have written most clearly on showing up regardless — Pressfield, Tharp, Currey.
  • Planned
    Walking, as a thinking practice
    Rebecca Solnit, Robert Macfarlane, Frédéric Gros. A short course on why the people who have thought most clearly all walked a lot — and what the research now says about why.

Personal finance and the cleaner-thinking layer underneath it.

  • In progress
    Seven foundational ideas — paying yourself first, compound interest, the true cost of debt — for someone starting from scratch.
  • In progress
    Housel, Robin, and Stanley/Danko. Personal finance as a study of the person, not the spreadsheet.

    Collins, Larimore, Malkiel. The case for low-cost index investing, from the most accessible voice to the most rigorous.

    Schelling first, then Nash, then the experimental literature. The minimum you need to read most current commentary on conflict and cooperation.

    Annie Duke, Philip Tetlock, Daniel Kahneman. How to think about a decision that hasn't happened yet — and how to grade it after it has.

  • Planned
    Forecasting, like a superforecaster
    Tetlock's research distilled. Probabilistic thinking, base rates, the inside and outside views, the discipline of updating.
  • Planned
    Effective altruism, fairly
    Singer, MacAskill, the post-FTX reckoning. The strongest version of the argument and the strongest version of the objections, in the same week.

Sales, negotiation & communication

  • In progress
    Seven foundational moves from Pink, Carnegie, and Rackham — for the person who has never thought of themselves as someone who sells.

Relationships & inner life

8 paths

The quietly central work. Friendship, attachment, the long-term partnership.

  • In progress
    Levine & Heller, Sue Johnson, Esther Perel. Three modern voices on adult romantic partnership — diagnosis, repair, the security-desire tension.
  • In progress
    Manson, Glover, Branden — explicitly anti-PUA. The argument: attractiveness is downstream of self-respect, not upstream of it.

    Friendship after thirty
    The literature is thinner than it should be. Aristotle, Robin Dunbar, Lydia Denworth. Why adult friendship needs scheduling — and what it takes to keep one alive.

    Grief, and the long after
    Joan Didion, C.S. Lewis, the contemporary clinical literature. Grief as a slow remaking of the self — not the five-stage tidy version.

Slow living & creative practice

    Pressfield, Rubin, Gilbert. Same problem — the inner block on creative work — three temperaments: military, monastic, playful.

    Solitude, on purpose
    Anthony Storr, Cal Newport, Sara Maitland. The neglected case that being alone — frequently, well — is a precondition for a thinking life.

  • Planned
    Cooking as a practice
    Samin Nosrat, MFK Fisher, Michael Pollan. The case that cooking is one of the last domestic places where attention still pays off — and how to take it seriously without becoming insufferable.

Science explainers

10 paths

The popular-science shelf, taken patiently. What the actual experts actually think.

  • Planned
    Science, an introduction

  • Planned
    Carl Sagan and the long view
    Pale Blue Dot, The Demon-Haunted World, Cosmos. Sagan as a stylist and as a steward — the case for science as a kind of patience.

    Lisa Feldman Barrett, Anil Seth, the careful contemporary neuroscientists. Why most popular neuroscience is a generation behind the field.

    What sleep actually does
    Why Walker's bestseller has been criticised, what the field actually agrees on, what a working adult should do with that. The honest version.
  • Planned
    Nutrition, uncertainly
    A patient walk through what nutritional epidemiology can and cannot tell you. Pollan's defensible rules, the few RCT findings that survived, why almost everything else is contested.

    Climate science, cleanly
    What the IPCC actually says, where the genuine disagreements are, what a serious adult should and shouldn't be worried about. Hayhoe, Mann, Hausfather.
  • Planned
    AI, beyond the hype cycle
    What's actually new since 2022, what isn't, and what serious people who disagree about the trajectory are arguing about. Christian, Marcus, Hassabis.

4 paths

    Newport's argument against the passion hypothesis, in full. Craftsmanship over passion, career capital, the slow build.
