The Mean and the System
How Aristotle defined what is right and how organizations support finding it.
This is the second in a three-part series exploring what Aristotle actually meant by praxis and why it matters for anyone leading teams or building things.
In Part 1, The Knowing-Doing Gap, I discussed how Aristotle taught that virtue cannot be taught through instruction alone; it must be built through practice and habituation. But knowing that character is formed through repeated action raises an immediate question: repeated action toward what end? What is the goal? If we’re constantly practicing something, what’s the target we’re aiming for?
Aristotle’s answer is “the doctrine of the mean”, and that means anything but average. The mean is not a compromise or a middle ground between extremes. It’s the right response for this person in this situation. Being able to nail that balance requires judgment that only comes from practice.
The Doctrine of the Mean
Aristotle’s practical insight for conduct is simple to state and hard to live: virtue aims at the mean between excess and deficit. Courage lies between recklessness and cowardice. Generosity lies between wastefulness and stinginess. The mean is not a mechanical midpoint. It is the fitting response, relative to the person, the circumstance, and the stakes, as determined by reason and practical wisdom.
As Aristotle defines it, “Virtue is a state apt to exercise deliberate choice, being in the relative mean, determined by reason, as the practically wise person would determine.”
This rescues virtue from being some simple moral arithmetic: courage is not 50% fear. Nor is it extremes applied indiscriminately; radical candor without tact or consideration. Virtue is the right response to this situation for this person right now. In leadership, the mean might look like candor with tact, speed with diligence, or thrift with generosity. Any of these virtues can be caricatured by excess or defect.
Three pairs you encounter every week:
Transparency. Defect: opacity, hoarding information. Excess: oversharing, paralyzing the team with every uncertainty. Mean: clarity about what matters when it matters.
Decisiveness. Defect: analysis paralysis, endless deferral. Excess: rashness, deciding before you understand. Mean: deliberate choice after proportional inquiry.
Accountability. Defect: blame-shifting, excuses. Excess: performative self-flagellation, martyr complexes. Mean: responsible ownership without drama.
The critical element is discernment: the mean is not static. It shifts with context. Practical wisdom is the capacity to read the situation and hit the mark. And like any capacity, it is acquired through repeated practice. A pilot does not learn to land in crosswinds by reading about crosswinds. She practices landing in progressively challenging conditions until the correct response becomes intuitive. The same holds for judgment. You learn to hit the mean by attempting it, noticing where you miss, and calibrating.
Voluntary Action and Responsibility
Aristotle ties praxis directly to accountability through his distinction between voluntary and involuntary action. He distinguishes them based on a simple principle: virtue concerns feelings and actions that are within our control, and praise and blame only make sense when we are talking about things we chose to do. If you were compelled by force or acted in unavoidable ignorance, the act may be involuntary. But if the action was genuinely in your power (if you could have chosen otherwise) then you own it. That power of voluntary action is what we sometimes refer to as agency.
Aristotle’s take on this is challenging. He refuses the comfortable evasions we reach for when things go wrong. You cannot outsource responsibility to the system, the process, or the framework. “The being good or vicious characters is in our power,” he writes. If you chose it, you are accountable for it, and that accountability is not contingent on success. The standard is not perfection but responsible authorship of your choices.
Its challenging because modern office politick suggests that we use noncommittal and nonjudgmental language specifically to avoid accountability. We say “the process failed” when what we mean is “we failed to follow the process” or “we designed a bad process and knew it,” or worse “we know the process wasn’t going to work, but we could or wouldn’t challenge it.” We say “there was a miscommunication” when what we mean is “I did not communicate clearly,” or “you did not inform the right stakeholders.” These are not merely semantic evasions: they are failures to claim or acknowledge agency. Aristotle’s clarity is useful here: if the action was within your power and you were not coerced or genuinely ignorant, it was voluntary, and if it was voluntary, your choice reveals something about your character.
This doesn’t mean cruelty in retrospectives; acting that way would not be adhering to the doctrine of the mean. What it does require is honesty about what was actually in our control, which paradoxically makes room for real compassion about what was not. It means distinguishing between blameless ignorance and culpable negligence, between constraints we could not overcome and constraints we chose not to address. It means taking seriously the choices we make and the people those choices are forming us into. A well-designed drill creates conditions where people practice making voluntary choices under realistic constraints, then reflects openly on those choices to improve judgment. The goal is not to assign blame but to cultivate better choosers.
Choice and Deliberation
At the center of Aristotle’s account of praxis is prohairesis, moral choice, which he distinguishes carefully from mere preference or wish. Choice is voluntary, but not all voluntary acts rise to the level of choice. A child acts voluntarily when she grabs a toy, but she is not exercising moral choice, she’s simply acting on impulse. Choice, for Aristotle, is “voluntary which has passed through a stage of previous deliberation.” It is the endpoint of reasoning, the moment when thought converts into committed action.
Deliberation (bouleusis in Greek) is reasoning about means, not ends. We do not deliberate about whether health is good or whether we want the systems we work with to be reliable; these are the goals we take as given. We deliberate about how to achieve health or reliability given the constraints, tradeoffs, and uncertainties we face. Deliberation weighs practical courses of action over which we have control and does not waste time on impossibilities or abstract universals. You deliberate about whether to add redundancy or improve monitoring, not about whether uptime is desirable in principle.
Good character anchors you, and orients you toward the worthy goals. Practical wisdom selects fitting means to reach those ends. It discerns which path is most likely to get you there under present conditions. The person of practical wisdom knows what she is trying to accomplish and can navigate the messy gap between aspiration and reality.
Good agents are not driftwood carried by circumstance. They clarify ends, survey options, weigh tradeoffs, and then decide. Analysis paralysis violates virtue as surely as rashness does, because both represent failures of practical wisdom. The mean lies between dithering and impulsiveness, and hitting that mean requires practice.
Emergency responders train this explicitly because lives depend on it. In tabletop exercises, they practice stating objectives clearly, identifying real options under constraint, weighing tradeoffs in real time, and choosing a course of action even when information is incomplete. The drill isn’t about getting the “right” answer (there often isn’t one) but about becoming the kind of person who can deliberate well under pressure. The more you practice deliberation in controlled conditions, the more reliably you can do it when chaos hits and the variables multiply.
Here’s a simple deliberation ritual for consequential decisions:
State the end. What are we actually trying to accomplish?
List real options. Not hypotheticals. Not wish-casting. Actual paths available to us.
Name likely tradeoffs. Every choice forecloses others. What are we giving up?
Choose and record why. Document the reasoning so you can learn from it later.
Set a review date. When will we know if this was the right call?
This isn’t heavyweight process but structured thinking: the externalization of the deliberative moves that Aristotle describes. It is the practice of deliberation, and practicing it forms people who deliberate well under pressure. The ritual is the drill. The repetition builds the capacity.
Calibrating Toward the Mean
Aristotle is realistic about human limitation. Hitting the mean is hard. We rarely land on the exact mark in one move. In his discussion of practical virtue, he acknowledges that “the mean state is in all things praiseworthy; we often deflect toward excess or defect as the easiest method of hitting the mean.”
Ethical accuracy requires calibration over time. You reflect on where you landed, notice whether you erred toward excess or defect, and adjust. This is not self-flagellation. This is honest calibration toward better judgment.
This is why after-action reviews exist. A military unit debriefs every operation, naming what worked and what missed the mark. The point is not punishment. The point is calibration. The unit that skipped reconnaissance this time might build in an extra recon pass next time. The unit that waited too long for perfect information might tighten the decision window. Each iteration refines the capacity to hit the mean under similar conditions.
In project retrospectives, this might mean naming explicitly where to nudge next time. “We erred toward speed and skipped load testing. Next time, build in two extra days for performance validation.” Or: “We erred toward caution and over-engineered the MVP. Next time, ship with fewer safeguards and instrument heavily.”
The goal is not to hit perfection. The goal is to cultivate the disposition that notices misses and corrects. That disposition is practical wisdom, and it is built through repeated cycles of action, reflection, and adjustment.
Law, Community, and the Shaping of Character
If you’re wondering what this means for a company or organization, Aristotle was on top of that question, too. He understood clearly that virtue does not grow in a vacuum. Individual willpower matters, but it’s insufficient. When examining how character is formed, Aristotle writes that lawgivers aim to make citizens good through habituation, and that “herein consists the difference between a good Constitution and a bad.” A good polity shapes its people toward excellence. A bad one degrades them through perverse incentives or neglect.
This is the bridge to organizational life. Our laws are policies, norms, and rituals. Our polity is the team, the company, the community of practice. Every incentive structure, every performance review, every decision about what gets celebrated and what gets quietly tolerated is an intervention in character formation. As with individual praxis, the most insightful questions aren’t about output. Its not whether we’re running drills (we always are) but whether the drills we’re running cultivate the responses we claim to value.
Culture is not the slogans on the wall; culture is the network of habits elicited by real consequences and reinforced by peers. A military unit that runs realistic combat drills under stress forms soldiers who can execute under fire. An organization that runs realistic decision-making drills under pressure forms leaders who can choose well when the stakes are high. The inverse is equally true: a culture that rewards heroics over sustainability will produce burnt-out heroes. A culture that punishes all mistakes equally will produce risk-averse bureaucrats. The system is not neutral. It is always shaping.
Ask of every practice: what kind of people does this make us become? If your incident response drills are theater (checkbox exercises with no real pressure), then under real pressure, your people will either blankly check the boxes or crack trying to figure out what to do. If your values discussions happen only in onboarding and never in real decision contexts, you’re training people to treat values as decoration and the will not honor them when the going gets rough.
You get what you measure.
~ Richard Hamming
The mean provides the target. Voluntary action creates accountability. Deliberation bridges thought and action. Calibration refines aim through feedback. Systems shape what gets practiced.
But none of this happens automatically. Systems can cultivate praxis or degrade it. Part 3 addresses the practical question: how do you install deliberate habituation in an organization? What does it look like when everyday work becomes a training ground for practical wisdom?
