The Beginning
Core Stoicism places happiness in correct assent. Only beliefs and will are in our control (Th6), so practice is the work of correcting one’s own assents until they match the truth about value.
Every act of that work is done by a certain kind of agent on a certain kind of object. The commitments name what that agent and object must be. This document traces what follows for the person doing the work.
The Claim
As a person comes closer to correct practice, he acts more and more fully from all six commitments.
What Practice Uses
Each act of correct practice uses one or more of the commitments:
- Locating himself inside the line of control. He treats what is in his control as himself and the rest as external (C1).
- Withholding or giving assent. He treats the act as his own doing, which could have gone otherwise (C2).
- Asking whether an impression is true. He treats it as a claim that matches what is or fails to (C5).
- Asking what the impression claims about value. He treats value as there to be got right or wrong (C6).
- Testing the impression against Th10. He traces a particular judgment back to what supports it (C4).
- Seeing what is fitting. He sees without proof that pain is dispreferred and that one ought, other things equal, not to aim at it. Sterling gives principles of this kind as known by “rational perception of self-evidence” (19 January 2015) (C3).
The practitioner does not perform these acts now and then. They are the practice. So the further he goes, the more constantly he acts from all six.
The Ordinary Man and the Practitioner
The ordinary man already acts from most of the commitments. He deliberates, blames, apologizes and says “that’s not what happened.” The structure is in place, but the content is false. His anger asserts that an evil was done to him, which is a claim about value in the form C5 and C6 require, and false against Th10.
The practitioner keeps the same structure and corrects the content. The difference between them is not that one holds the commitments and the other does not. One acts from them with false judgments, and the other with true ones.
Holding in Act and Holding in Profession
To act from a commitment is not the same as to profess it. Correct practice has stood beside a professed denial.
The early Stoics practised while teaching fate. Sterling says the early school “advanced two logically incompatible doctrines,” and that the later Stoics, “Epictetus foremost among them,” set aside the one that did more damage. Of the determinism he writes that it “is corrosive with respect to Stoicism, and in this one case I actually think ancient Stoic Physics hinders Stoic Ethics” (4 September 2019). His note to Th21 says strict determinism would make acts of vice “not actually in our control in any important sense.”
The ancient corporeal soul is a partial case. On the ratified reading in C1 — What the Commitment Carries: A Study Note, the self C1 requires is a subject, single, and not physical. The ancient soul had the first two marks and lacked the third. Sterling says his dualism “is not developed in opposition to the ancient Stoic metaphysics, but to modern scientific physics.” The clear case of practice beside a professed denial is C2.
The ethics survived the denial because it never rested on the physics. Sterling’s test case: “If you had somehow convinced Zeno that fiery pneuma was not in fact a material substance or that there was no conscious mind at the heart of the universe, I do not think that he would have abandoned his belief that virtue was good” (5 June 2017). The ethics and the physics were connected, not related as foundation and building.
What Practice Does to the Replacements
Practice does not remove a professed denial by itself. It makes the denial harder to hold consistently.
A man who withdraws his assent every day and says “that was up to me” is stating C2 aloud, whatever theory he would give if asked. A man who calls his own value judgment false is stating C5 and C6. As practice advances, the gap between what he does and what he says narrows. Argument is what closes it.
Hiding behind a replacement is the same movement run backward. The replacement serves as an excuse for oneself, while the commitment is still applied to everyone else. Sterling’s case is the debtor: “the same man who does not repay a debt and pretends that he has no obligation to do so gets furious when someone else does not repay a debt to him” (26 May 2021). Practice takes away that excuse, because it applies the commitment to oneself first.
The Order of Teaching
The commitments are not the starting point of teaching. Sterling’s beginning is the truth about value: “The Stoics think that we already know (basically) what Virtue is, and we already know that it is good. ... So you cannot get someone started on the road to eudaimonia without directly confronting them with the truth that externals are neither good nor evil” (5 June 2017).
This fits his account of how ethics relates to metaphysics. Stoic ethics is not derived from non-ethical premises, so the commitments are not premises the student must accept before he begins. They are what he finds he has been relying on once the practice is under way. The order is Th10 first, then practice, and then recognition of the commitments the practice uses.
What This Document Does Not Claim
- That practice proves the commitments true. It shows that practice uses them, which supports the corpus’s claim of necessity and not a claim of truth.
- That a practitioner must profess them. The early Stoa shows otherwise.
- That the commitments should be taught first.
- That ordinary people demonstrably act from most of the six. That rests on the corpus’s argument from what ordinary acts presuppose and on survey research recalled, not verified.
Derivation trace. This essay has been audited with the Derivation Trace Instrument, which checks whether each claim names what it rests on. The verdict was Partially Traced. One claim under the thesis, "They are the practice," names no support, and three steps were found to loosen rather than derive. See DTI Run — The Commitments in Practice v0.1 — Version 1.0.
