PRACTICAL GUIDE TO HANDLING IMPRESSIONS

Sterling's Core Teaching Translated Using the Stoic 500

---

THE BASIC COGNITIVE SEQUENCE

I receive **Phantasiai (Impressions, 1)**. For now, let us take these as being outside our control. These impressions are cognitive and propositional—they are not uninterpreted raw data, but rather ideas that claim reality is a certain way.

I do not see a collection of colors and patterns—I "see" my backpack sitting on the chair in front of my desk. Some impressions possess **Event-Neutrality (404)**—there is nothing good or bad about my backpack being on my chair.

But other impressions contain **Value-Detection (66)** challenges. Suppose I remember leaving my backpack on the floor when I left—I might now have the impression: "my backpack is on my chair, which means someone has intruded on my office, which is a very bad thing!"

This impression smuggles in an **External-Illusion (30)**—the false appearance that an **External-Event (26)** (someone entering my office) is evil.

---

THE POWER OF ASSENT

As I said, for the time being we assume these impressions are not in our control. But what *is* within the **Internal-Domain (21)** is how we react to them.

We exercise **Prohairesis (7)**—we can grant **Sunkatathesis (Assent, 2)**, or withhold it. That is, we can accept that a given impression is true, or reject it as unproven or false.

A few minutes ago, I granted **Correct-Assent (91)** to the impression that my backpack was on the chair. I didn't have to, but I did.

The process of assenting is cognitive (occurring in the **Hēgemonikon/ruling faculty**), but very seldom explicit. My acceptance was so simple and momentary that it seems things passed directly from impression to belief. But that isn't how it works.

I *could* apply **Rational-Pause (71)** and **Cognitive-Suspension (72)** even now—really committed skeptics might be able to do this in ordinary cases—I just don't.

---

THE CONSEQUENCES OF ASSENT

If I apply **Assent-Withholding (87)**, refusing to assent to an impression, nothing happens. No emotion, no action, nothing.

If I give **Incorrect-Assent (92)** to an impression with a value component, then **Hormē (Impulse, 3)** will result. I will experience **Orexis (Desire, 4)** that the "good" thing happen, or **Ekklisis (Aversion, 5)** that the "bad" thing not happen.

If the impression says this outcome has *already* occurred, then a **Pathos (passion/irrational emotion)** will result—in the example above, likely anger or fear. These are positive feelings if the impression depicted something good, negative feelings if "bad."

This may lead to another impression. Assenting to it will lead to action. For example, I might have the further thought: "It would be good for me to go find out who has been in my office." If I assent to this idea, then I will stalk angrily down the hall to demand an explanation.

---

THE CENTRAL PRINCIPLE

All of this sounds complicated, but it reduces to this:

Everything in the Stoic system comes down to assent to impressions.

Choosing whether to grant **Sunkatathesis (2)** is the only thing in our control...and yet, everything critical to leading the best possible life is contained in that one act.

All our desires, emotions, and actions are tied to assenting to impressions.

- If I achieve **Impression-Mastery (94)**, getting my assents right, then I have guaranteed **Eudaimonia (flourishing/Telos-Achievement, 471)**.

- If I grant even one **Incorrect-Assent (92)**, I cannot have eudaimonia.

---

INDIRECT CONTROL OVER IMPRESSIONS

I said we would assume original impressions are not in our control. Directly, that's true. But indirectly, it isn't, for two reasons:

A) Character Formation Through Repeated Assent

Our impressions are closely connected to Ēthos (Character, Tier 7) 

Through **Training-Repetition (363)** and **Assent-Habit (93)**:

- If you reject an impression, that type becomes less common and weaker

- If you assent to it, it becomes more common and stronger

If it seems to me that it would be good to punch someone for insulting me, and I assent, then it becomes more likely that the next time something annoys me it will seem I should lash out, and that 'seeming' will be more compelling.

If I apply **Assent-Withholding (87)**, if I tell myself "hitting them won't solve my problems," then I will have fewer "I should punch someone" impressions, and they will be weaker (more easily resisted through **Error-Interruption (377)**).

So by being careful with our acts of assent (which are within the **Internal-Domain (21)**), the impressions we receive will be altered over time through **Character-Formation (Tier 7)**.

This is a long process involving **Training-Endurance (365)**, but is critical—this is building **Virtue-Directed Character**. 

The **Sophos (Sage, 468-469)** is simply someone who has controlled their assents through **Daily-Mastery (398)** for such a long period that they no longer receive false **External-Illusion (30)** impressions (that externals are good or bad) in the first place. They have achieved **Prohairesis-Perfection (470)**.

---

B) Formulating Alternative Impressions**

While our impressions are not in our control, we have the ability (suggested in examples above) to formulate new ideas through **Deliberation (12)**.

I receive the impression: "Someone has been in my office—that's a very bad thing."

If I manage to apply **Assent-Withholding (87)**, I can choose to formulate an alternative impression through **Rational-Refinement (80)**:

**"It seems someone has been in my office, but that is an External-Event (26), therefore an External-Indifferent (28)—neither good nor bad."**

This proposition demonstrates **Domain-Clarity (49)** and I can correctly grant **Correct-Assent (91)** to it.

I receive the impression: "I should punch this guy in the nose."

If I reject it through **Error-Interruption (377)**, I can formulate some alternative idea through **Counter-Image-Check (75)**.

One of my favorite passages in Epictetus suggests: if you hear someone has been criticizing you, don't try to defend yourself, but instead say: "Obviously he doesn't know my other faults, or he wouldn't have mentioned these."

I wonder how much gossip and feuds would have been prevented if people reacted like that—maintaining **Internal-Sovereignty (423)** and **External-Indifference (52)**.

---

THE PRACTICAL PROGRAM

What we should be striving for through **Training-Preparation (360)** and **Morning-Preparation (371)**:

A) Refuse False Value-Impressions

**Don't assent to impressions that depict externals as either good or evil.**

Apply the **Internal-External-Test (68)**:

- Does this impression attribute value to something outside **Prohairesis (7)**?

- If yes: apply **Assent-Withholding (87)**

This maintains **Domain-Clarity (49)** and prevents **External-Dependency (36)**.

---

B) Refuse Immoral Response-Impressions

**If we fail 'A', don't assent to subsequent impressions that depict immoral responses as appropriate.**

Even if you've granted **Incorrect-Assent (92)** to an external-value claim, you can still apply **Error-Interruption (377)** before acting.

The impression "I should retaliate" can be caught through **Vigilance-Intensity (382)** and rejected through **Error-Correction (378)**.

---

C) Consciously Formulate True Value-Propositions

**Consciously formulate true propositions regarding the External-Indifference (52) of external things.**

Through **Event-Forecasting (373)** and **Obstacle-Preacceptance (374)**, do this in advance.

**Remind yourself through Morning-Preparation (371):**

- Your own life and health are **Preferred-Indifferents**—neither good nor evil

- The lives and health of those around you are **External-Events (26)**

- Your job, reputation, possessions are all **External-Indifferents (28)**

**Whether or not you have done so in advance, try to do so at the time:**

*"I have pictures here of your wife having sex with another man."*

**Apply Neutral-Observation (63) and Rational-Pause (71):**

'My wife's actions are not in my control—they belong to the **External-Domain (22)**. They are neither good nor evil. My happiness is in my control, not enslaved to the actions of others. I maintain **Internal-Freedom (20)** and **Self-Sufficiency (37)**.'

---

D) Consciously Formulate True Action-Propositions

**Consciously formulate true action propositions demonstrating Kathēkon (appropriate action).**

*"I should report truthfully to my boss regarding sales numbers: truth-telling expresses **Wisdom (Sophia)** and **Justice (Dikaiosunē)**, and I have a duty to act faithfully at work. If my boss fires me, I should remember that my job is an **External-Indifferent (28)**, neither good nor evil."*

By paying attention to **Preferred-Indifferents (Tier 6)** and to the duties connected with various roles in life, I can recognize what would actually demonstrate **Virtue (Tier 8)** in each situation through **Deliberation (12)**.

Bring this consciously to mind through **Prosochē (Attention, 10)**, and grant **Correct-Assent (91)**.

---

E) Acknowledge Correct Actions

**When you act correctly, assent to the proposition that you have done a good thing—then you will experience Eupatheia (rational good feeling), particularly Chara (joy).**

This is recognizing that you have achieved **Internal-Good (27)**—virtue expressed in action.

Even if you are still a **Prokoptōn (progressor)** rather than a **Sophos (Sage)**, acknowledge your **Katorthōma (right action)** or **Kathēkon (appropriate action)**.

---

F) Character Transformation Over Time

**Over time through Training-Repetition (363) and Daily-Mastery (398), my Ēthos (Character) will change such that:**

- I no longer have the false value impressions from 'A' and 'B'

- Steps 'C', 'D', and 'E' become routine through **Assent-Habit (93)**

- I achieve **Character-Stability** and approach **Virtue-Directed Character**

**This is Eudaimonia (Telos-Achievement, 471)**—**Eupatheiai (good feelings)** combined with **virtuous actions**.

This represents **Prohairesis-Perfection (470)**, the perfected state of the ruling faculty operating with complete rational consistency.

---

DAILY APPLICATION

Through **Morning-Preparation (371)** each day:

1. **Event-Forecasting (373)** - Anticipate likely impressions

2. **Obstacle-Preacceptance (374)** - Pre-accept that challenging impressions will arise

3. **Vigilance-Recognition (380)** - Commit to watching for false value-claims

Throughout the day:

1. **Prosochē (Attention, 10)** - Notice impressions as they arise

2. **Value-Detection (66)** - Identify hidden value-claims

3. **Internal-External-Test (68)** - Apply the fundamental criterion

4. **Rational-Pause (71)** - Create space for examination

5. **Correct-Assent (91)** or **Assent-Withholding (87)** - Choose wisely

Through **Evening-Review (372)**:

1. **Examination-Depth (368)** - Review the day's assents

2. **Error-Integration (379)** - Learn from mistakes

3. **Practice-Completion (400)** - Close the day with satisfaction

This is the path to **Impression-Mastery (94)** and ultimately **Telos-Achievement (471)**.
