The phlegmatic's problem is not starting; it is changing state. The popular caricature paints them as the slow one, the lazy one, the one who is never in a hurry, and that caricature is wrong twice over: because there are very hardworking phlegmatics, and because the same person who struggles to start a task may struggle just as much to stop it once it has begun. What the phlegmatic structure makes costly is not action, but the passage from one settled configuration to another.
Transition and the preservation of state
If the phlegmatic is at rest, starting costs. If they have settled into a stable work routine, interrupting it also costs. And once a new routine has stabilized, it in turn comes to be preserved and defended. That is why it is more accurate to speak of the preservation of state than of slowness: a phlegmatic can be an excellent worker within a routine and firmly resist whoever tries to interrupt it, and at the same time find it hard to sustain an activity in which each stage calls for a new initiative. The question, in their case, is not how much they do, but how much it costs them to reconfigure themselves.
Preserving, it must be said, is also a positive capacity. The phlegmatic maintains continuity, protects commitments already made and keeps each new stimulus from undoing an order that had value. In homes, companies and communities where everyone wants to change everything all the time, it is often the phlegmatic who holds on to what needed holding. The method calls the operation with which they respond to their matter stability, that is, sustaining a configuration through time and change, and pictures it as moisture and plant life: bond, continuity and growth without noise.
Inhibition is not shyness
In the method's sense, inhibition is this greater barrier to turning a possibility into a new mobilization. It does not mean shyness, introversion, fear or incapacity, and it can exist in a person who is friendly, talkative and brave. Reason may have concluded perfectly well what must be done, and the mobilization may still have to get through the cost of the passage.
Hence a phenomenon the phlegmatic knows well and others tend to misjudge: knowing exactly what they ought to do and still not doing it. The logic lies not in a lack of judgment, but in the cost of covering the ground between judgment and execution. And that is also why deadlines, obligations, positions and routines help them so much: they reduce the amount of mobilization that has to come from them alone. For a phlegmatic, there is an enormous difference between "I need to decide when to start" and "this starts at eight." You can see this already in children: faced with an ambiguous situation, the phlegmatic child tends to wait, observe and look to the adult before stepping in.
Conflict and anger
Conflict demands exactly what the phlegmatic feels most: interrupting a state, producing tension, sustaining a response and perhaps reorganizing how people live together. That is why they tend to avoid it, and that avoidance should not automatically be praised as meekness. The phlegmatic feels anger, sometimes a great deal of it; what there is in them is a greater distance between feeling anger and turning it into confrontation. The popular rule that they "bottle everything up and one day explode" describes some cases, but it does not define the temperament.
In my observation, there is also in them a form of resistance that deserves a name: the phlegmatic can recognize that an order is reasonable and still resist it in silence, when they feel they have been stripped of authority over when and how they will go through the change. It is not a desire to command others; it is the defense of their own time to move. From this defense arise three appearances that should not be confused: agreeing without acting, leaving a bad situation instead of reforming it and resisting an order without confronting it openly. None of them, on its own, is enough to say that someone is phlegmatic, because fatigue, fear, habit or legitimate disagreement can produce the same things.
What the phlegmatic is not
The phlegmatic is not the lazy, the cold or the indifferent one. Laziness is a vice, and temperament is not a vice; coldness is an affective tone, which belongs to the other axis; and indifference is an absence of love, which has nothing to do with the cost of moving. Nor is the phlegmatic simply the calm one, because calm can come from peace, but it can also come from flight. If the supposed phlegmatic presence only shows up as observed slowness, the concept has been reduced to a stereotype; what remains phlegmatic in all its forms is the relationship with transition.
Prudence: the capacity and the virtue
In the created order, the phlegmatic has an aptitude for certain operations of prudence, and the possible fruit of that aptitude is a stable peace, which is not the absence of tension. The ease of not rushing favors waiting, observing and preserving, and the mature phlegmatic tends to look for the ways that accomplish the good with the least necessary degree of disturbance. But here the bridge between temperament and virtue is especially delicate, because true prudence is not only not rushing: it has to command action when the hour comes. The immature choleric tends to act before having considered enough; the immature phlegmatic tends to go on not acting after having already considered enough. These are two errors opposed in time, and prudence corrects both.
The phlegmatic's particular risk is missing opportunities because they waited until reality decided for them. The question that measures their maturity is therefore this: can I get myself moving when the good demands that I disturb my stability?
The fall: peace that protects comfort
In the wounded condition, stability can be made absolute until the natural difficulty of moving starts to count as an argument against the good one has recognized. This is phlegmatic egoization: "getting myself moving costs me" becomes "if this demands too much disturbance, maybe it should not be done," and willingness to act begins to define duty. By this path comes lukewarmness. But one must be fair: inhibition is not lukewarmness, fatigue is not lukewarmness and the legitimate need for rest is not lukewarmness. Lukewarmness appears when there is a sufficiently recognized good, there is a real possibility of acting, and the person habitually leaves undone what they ought to do in order to preserve comfort, stability or their own immobility. The structure shows where to ask; it never authorizes condemning anyone for a pause.
The underlying fear of this fall is that of disturbance and imposed change, and the thesis the phlegmatic self builds is usually this: I have to keep the peace, protect my space, avoid wearing myself out and not let myself be broken. From this come the vices that go with it: omission, complacency, flight from necessary conflict and passive resistance to any demand that comes from outside.
The mature phlegmatic
Maturity does not make the phlegmatic stop feeling the cost of transition. They go on feeling it, and may feel it all their life. What changes is that they learn to distinguish useless disturbance from necessary disturbance, and begin to act in the face of the second, even when it costs them. It is a stability that knows how to move, and that recognizes the moment when preservation has stopped being prudence and become omission.
The formula of this maturity fits in one sentence: do not act too soon, and do not fail to act when the hour has come. And there is something deeply evangelical in this peace that, without losing its meekness, accepts being disturbed by the good, because the peace Christ leaves to his own is not the peace the world gives (Jn 14:27), and the mature phlegmatic finally discovers that their tranquility was not made to shield them from the call, but so that they might answer it without losing their serenity.
The species of the phlegmatic
The phlegmatic governs three species: the phlegmatic-sanguine, the pure phlegmatic and the phlegmatic-melancholic. It also takes part, in the service of another end, in the sanguine-phlegmatic and the melancholic-phlegmatic.
