The stack of your principles

In the previous essay, I described how mental models generate axioms that ground maxims in understanding. The stack underneath your principles - the reasoning that makes them coherent.

But there’s another kind of stack worth examining. Not the one beneath your principles, but the one among them. The ordering.

Because you don’t hold just one principle. You hold many. Freedom of expression and responsibility for consequences. Privacy and security. Integrity and survival. Loyalty and honesty. Growth and sustainability. Profit and ethics.

The problem is that these principles don’t exist in isolation. They collide. They contradict. And when they do, something interesting happens: your actual principle stack¹ - the one that really governs your behavior - becomes visible.

The Revealed Stack # #

You can claim whatever principles you like. But your actual stack reveals itself in the moment of conflict.

Consider Facebook and privacy. In the early years, when the company was fighting for survival, growth was necessarily near the top of the stack. That made sense. A startup that doesn’t grow doesn’t exist. But as Facebook matured - became dominant, profitable, powerful - the context changed completely. The stack should have reorganized. A company with Facebook’s resources and position could have made privacy a top principle. The fact that it didn’t reveals what was actually being chosen.

For years - decades - the company articulated a principle: user privacy matters. It appeared in mission statements. It showed up in public commitments. It was woven into product philosophy.

But when privacy conflicted with engagement metrics (which drove advertising revenue), the stack became clear. Privacy was not at the top. It was somewhere much lower, buried beneath growth, engagement, and profit.

This wasn’t a secret. The evidence was everywhere. Terms of service changed. Data collection expanded. Opt-out became harder. Users complained. Regulators noticed. And yet the behavior continued, because the actual principle stack - the one revealed through sustained choice - hadn’t changed even as the conditions that might have justified it did.

The interesting part is that Facebook probably believed in privacy as a principle. It’s not that the executives were cartoon villains who didn’t care. It’s that when push came to shove, other principles won. And they kept winning. And at some point, what you choose repeatedly is your stack, regardless of what you claim.

But this matters even more in the context of time and circumstance. The stack that made sense at one stage of the company’s life - survival-focused, growth-driven - became a choice at a later stage, when different stacks were actually possible.

The Stack Through Time # #

Here’s what complicates the picture: your principle stack isn’t fixed. It shifts.

A young engineer entering the workforce might have integrity and craftsmanship high in their stack. These are principles they can afford. They have few dependents, minimal financial obligations, options if they walk away from a bad situation.

Then they get married. Buy a house. Have a child. Health insurance becomes critical. Suddenly survival is higher in the stack than it was before. Not because they’ve become corrupt or abandoned their values - but because the weight of actual responsibility has changed. They have people depending on them.

This isn’t moral failure. It’s adaptation to circumstance.

Similarly, a startup founder’s principle stack when they’re bootstrapped and fighting for survival looks very different from their stack once the company is stable and profitable. When you might not make payroll next month, growth and survival naturally sit higher than long-term sustainability or work-life balance. When you have runway, you can afford different principles.

And as you live longer, you learn things about yourself. What you thought you valued, you discover you don’t - or vice versa. You find that autonomy matters more than you expected. Or that community does. Or that leaving a legacy matters in ways you didn’t anticipate. Your self-knowledge increases, and your stack reorganizes accordingly.

This is all entirely normal. Expected, even. The stack you have at 25 managing your own code is not the same as the stack you have at 45 managing a team. Neither is right or wrong - they’re adapted to different contexts.

But here’s what makes it morally significant: even as your circumstances change, you’re still making choices about how to reorganize your stack. You can choose to maintain integrity even when survival pressure increases. You can choose to keep craftsmanship high even when speed is more profitable. You can choose to reorganize your stack as your context changes, rather than defaulting to whatever pressure pushes you.

The point isn’t that your stack should stay the same. It’s that you should be aware when it’s changing, and why.

Stacks in Transition # #

This is where the Facebook example gets more complicated and more revealing.

In the early days - the first few years - Facebook’s stack made sense. Growth was survival. User privacy was less of a technical or ethical priority than user engagement. The context demanded it.

But Facebook didn’t stay small. It became the largest social network in the world. It became profitable, powerful, essential infrastructure. The context changed completely. A company in that position - with those resources, that dominance, that responsibility - could have reorganized its stack. They could have elevated privacy, ethics, long-term thinking.

The fact that it didn’t reveals a choice. Not a forced circumstance, but an actual choice to keep the stack organized around growth and profit even after the conditions that made survival the priority had long passed.

This is the moment where the revealed stack becomes damning. It’s not the scrappy startup. It’s the mature company making the same choice it made when it had to, even though it doesn’t have to anymore.

For individuals, the equivalent is keeping the stack you needed to survive in hard times, long after you no longer need to. The person who clawed their way out of poverty and built security, but never reorganizes their principles once they have actual security. They keep operating as if survival is at the top, even though it isn’t anymore. That’s not adaptation - that’s inertia wearing the mask of principle.

The Impossibility of Prediction # #

Here’s what I don’t think is true: that you can know your principle stack in advance.

This isn’t just because most people don’t sit down and consciously order their values. It’s also because your stack will change as your circumstances change. The stack that fits your life at 30 won’t fit your life at 40. The stack that works when you’re secure won’t look the same as the stack you needed to survive precarity.

You can make educated guesses about what matters to you. You have values. You have convictions. But the actual ordering - which principle will win when two collide - often remains unknown until the moment comes. And even if you predict accurately today, that prediction might be obsolete next year.

It’s easy to say “I value integrity and profit equally” when profit isn’t threatened. It’s a different question when your income depends on looking the other way, or when you have mouths to feed and the integrity costs you something real.

It’s easy to say “I believe in free expression and responsibility” when you’re not the one managing the platform where harmful speech is happening.

It’s easy to say “I prioritize sustainability” when the sustainable choice doesn’t cost you anything. It’s harder when it means less income, more complexity, fewer options, delayed growth.

The stack doesn’t reveal itself through introspection. It reveals itself through behavior, under pressure, over time. And it reveals itself anew in each new context you enter.

This is why so many principles-related failures feel like surprises to the people committing them. A manager genuinely believes they value employee wellbeing. Then the quarter goes badly and they lay people off. They weren’t lying before - they were just encountering a situation where another principle (survival of the business, performance metrics, shareholder returns) was higher in the stack than they’d realized. And in that moment, facing that particular pressure, their stack reorganized itself.

It’s not that their earlier claim was false. It’s that their stack was always contextual - shaped by what they’d faced, what they needed to survive, what they’d been forced to choose. Put them in a new context with new pressures, and the stack shifts.

The Capitalism Problem # #

There’s a structural issue worth naming here: capitalism creates a powerful gravitational pull toward certain principles at the top of the stack.

In a system where your survival - or success, or comfort, or growth - depends on financial metrics, profit naturally migrates upward in your principle hierarchy. It doesn’t need to be intentional. It’s just physics.

You can have beautiful principles about quality, craftsmanship, taking care of your team. But if the financial system rewards the opposite - if speed to market beats quality, if headcount reduction beats employee wellbeing, if growth beats sustainability - then every day you’re making micro-choices that slowly recalibrate your stack.

Not because you’re corrupt or cynical. Just because the incentive structure works. You compromise a little here to hit a deadline. You defer investment there to improve margins. You rationalize a decision about labor or materials or safety because “everyone does it.” And bit by bit, the stack reorganizes itself around what the system actually rewards.

This isn’t unique to capitalism. Any system - political, social, organizational - creates incentives that push certain principles higher in the stack. But capitalism is particularly effective at it because it operates on a clear quantifiable metric (profit) that’s easy to track and compare.

When profit is the scoreboard, it becomes hard to argue that it shouldn’t sit near the top of your stack.

The Choice That Remains # #

But here’s where personal accountability comes in. And why this matters.

Even if the system is pushing in a certain direction, you still have a choice about your stack. Not an easy choice, usually. Not a choice without cost. But a choice nonetheless.

You can choose to take less profit in exchange for higher principles. You can choose to accept less growth to prioritize sustainability. You can choose to walk away from an opportunity because it violates something deeper.

People do this. Some do it consistently. They don’t get rich. They don’t maximize. They don’t win by the scoreboard that everyone else is watching. But their principle stack is coherent, and they know what they’ve chosen.

More commonly, people don’t make this choice. They work within the system. They optimize for what the system rewards. They tell themselves stories about how their hands are tied, how this is just how the world works, how you can’t change the system from outside so you might as well succeed within it.

Those are not illegitimate stories. The constraints are real. The pressure is real. The cost of defection is real.

But it’s still a choice.

And I think the clarity that comes from acknowledging that choice - understanding your actual stack, not your claimed stack, and recognizing that you’re choosing it every day - might be more important than getting the stack “right”.

Because you probably won’t get it right. You’ll probably find that some of your principles aren’t where you thought they were. You’ll discover that you value comfort more than you admitted, or that you’re willing to sacrifice more for community than you expected. You’ll encounter situations you didn’t anticipate and make choices you didn’t know you were capable of.

That’s not failure. That’s information. That’s how you actually come to know yourself.

What to Do With It # #

If your principle stack is revealed through choices, and if you can’t know it in advance, what’s the point of thinking about it?

The point is this: you can become aware of the revelation as it happens. You can feel when principles collide and notice which one wins. You can ask yourself: did I choose that? Or did I just default to whatever the system was pulling me toward?

That awareness doesn’t guarantee you’ll change your behavior. But it opens the possibility of doing so. It lets you see the cost of your choices rather than pretending they weren’t choices at all.

You can look at your actions and say: this is my stack. These are my priorities, whether I intended them to be or not. This is what I actually value, as demonstrated by what I actually do.

And then you can ask: is this the stack I want? And if not - if you discover that profit is higher than integrity, or convenience is higher than principle, or self-preservation is higher than ethics - then you at least know what would need to change.

It might be hard. It might be costly. It might require sacrificing something you’re not willing to sacrifice. But at least you’d know the choice you were making.

That’s more honest than most people manage. It’s also the only place where real change becomes possible.
