C1 and C2 Together — The Agent, the Chain and the Theorems: A Study Note v0.1

 

C1 and C2 Together — The Agent, the Chain and the Theorems: A Study Note v0.1

Theoretical foundations: Grant C. Sterling (Eastern Illinois University). Analysis and synthesis: Dave Kelly. Prose rendering: Claude (Anthropic). 2026.


I. Beginning

The chain, as Core Stoicism gives it: Th1, Th2, Th3 with lines 4–5, Th6, Th7 with line 8, Th10 with lines 11–14. The pair is studied wherever the proof says “in our control.” Canonical numbering: C1 Substance Dualism, C2 Libertarian Free Will, C3 Ethical Intuitionism, C4 Foundationalism, C5 Correspondence Theory, C6 Moral Realism.


II. Sterling Primary Added Here

  • Core Stoicism, 19 Sep 2005. Line 5 holds only “[if it is possible to control your desires].” The note at Th21: strict determinism would mean acts of vice “are not actually in our control in any important sense. But I don’t think strict determinism about internal states is a core belief of Stoicism.” The close: “Judgment is in our control.”
  • Excerpt 4. Startlement and “physical pleasures and pains” are “indifferent externals.”
  • Excerpt 5. “My identity is defined as the rational part of me, the part that chooses. Therefore, only things that this part of me does can really be good or bad for me.”
  • Excerpt 7. Impressions are out of our control; “what is in our control is how we react to them.” The Sage no longer receives “the false value impressions … in the first place.”
  • Excerpt 10. “My ‘action’ is my choice, not anything I physically do,” appropriate “at the instant the choice is made.”
  • 3 Sep 2019 (read as quoted). “Being in my control is a requirement for something being good or bad.”

III. Corpus Synthesis

The Six Commitments Integrated with the Core Stoicism Theorems v1.0: C1 grounds Th6 and Th3; C2 grounds Th6’s positive half and Th27; together they are “the agency axioms.” Props 1–58 are a synthesis from the Nine Excerpts, not Sterling’s enumeration. Section IX is later construction.


IV. Readings

The relation

  • R1. One fact, two aspects. C1 names the self by C2’s act: “the part that chooses.” C1 gives the agent, C2 the agency.
  • R2. The dependence runs one way. A soul that is not physical could still be necessitated, so C1 does not give C2. On Sterling’s premises C2 needs C1: Acts of Reason must be mental, and the physical world not closed.
  • R3. The self is narrower than the mind. Felt pain, startlement and arriving impressions are mental, yet he counts them external or out of our control. The chain’s line runs between what the faculty does and what it undergoes. C2 draws that line.
  • R4. Three lines coincide: what I am, what I control, where good and evil can lie. The pair makes the first two one line. Th10 with line 11 puts the third inside it.

Place in the chain

  • R5. The pair enters the proof at one basic theorem, Th6, and discharges the bracket at line 5. C1’s unity of the faculty enters separately, at Th7.
  • R6. The pair also carries the last step across. Lines 11–12 reach “externals are never good or evil” only through Th6. Excerpt 5 reaches it from identity directly. That second route gives a requirement only. Th10 still supplies that virtue is the good.
  • R7. The closing guarantee is the pair’s. It holds while the faculty functions (2013 post).

Ground

  • R8. Theorems. If Th6 goes, so do lines 8, 9, 11, 12, 13, 14, 28, 29, 2* and the guarantee. That is more than Sterling lists as falling with Th7. Th27 with Excerpt 10 puts action in the choice. Th18–19 mark the undergoing side.
  • R9. Propositions. C1: Props 3–5. C2: 10–11, 52. Joint: 8, 16, 18–19, 32, 34, 38, 53, 57–58, and 59, 62–63. Props 1–2 state theological determinism, which Sterling says Stoic Ethics does not need (4 Sep 2019), yet they share a section with 3–5.
  • R10. C1’s necessity can now be assembled from Sterling’s own words: unity (25 Oct 2013), not physical (through C2), identity (Excerpt 5). Only the full Cartesian form stays at “fits much better.”

V. Amendments Indicated


VI. Open Items

  • The “Self-Blame” and “Control” threads are unopened. The “zero-sum argument” may be there.
  • R6’s second route rests on a premise Sterling calls “plausible”: that my good must be my own doing.
  • Excerpt dates are undetermined.
