What are the Most Basic Moral Facts

 

What are the Most Basic Moral Facts?

The corpus answers this with precision. The most basic stratum is a single pair of claims — Theorem 10 of Core Stoicism: only virtue is genuinely good; only vice is genuinely evil. Sterling identifies the basic theorems as unprovable fundamental postulates defensible only by appeal to intuition of their truth — Theorem 10 is not derived from prior premises; it is directly apprehended. These function as the epistemic base of the system: not inferred from prior claims, directly apprehended, serving as anchoring principles on which all other Stoic judgments ultimately depend.

Both halves carry independent weight. Virtue is good in itself, constitutively, by the nature of what virtue is — not as a means, not because it produces preferred indifferents, not because rational agents would agree to value it. And on the other side, losing property, dying, being humiliated are not evils but dispreferred indifferents; vice alone is genuinely evil because it alone is the agent’s own failure to be what he is as a rational being — and that asymmetry is the hinge on which the entire corrective structure turns.

The first derived moral fact follows immediately: the claim that externals are indifferent is not an isolated assertion; it is grounded in the more fundamental truth that only virtue is genuinely good. The C3 essay gives the full roster of moral facts at this level: that virtue is good, that vice is evil, that externals are indifferent, that role-duties are genuine obligations — features of reality we can either recognize or miss, not rules we impose on experience.

Two properties complete the picture. These facts are mind-independent: the agent who sincerely believes wealth is a genuine good is still wrong; sincerity, cultural formation, and near-universal human tendency do not make the belief true. And they carry the whole system’s weight — if there are no objective moral facts, the Stoic project fails utterly.

So the structure: Theorem 10 is the bedrock pair; the indifference of externals is its first derivation; role-duties extend the facts into the agent’s situated obligations; and everything tested at Examination is tested against this base.

Thank you. However there is maybe no correspondence reality between role duties and virtue, as show the reality of concentration camps in the nazi period or the actual behavior of Israeli armed forces.. Even more, despite the latter evolution of Stoicism, in the Roman Empire, the Greek foundator of Stoicism, Zeno, was strongly influenced by cynics, that questioned and even refused social conventions, it means role duties. Zeno even wrote a book, that we still have, really insurgent concerning the social order in its different aspects

Commentary corrected in English by the AI Claude (Anthropic) :
Thank you. However, there may be no real correspondence between role duties and virtue, as the reality of the Nazi concentration camps, or the current behavior of the Israeli armed forces, makes painfully clear. Furthermore, and despite the later evolution of Stoicism within the Roman Empire, it is worth recalling that Zeno, the Greek founder of Stoicism, was deeply influenced by the Cynics — who questioned and even rejected social conventions, that is to say, role duties. Zeno himself wrote a book, which has come down to us, that is genuinely insurgent in its challenge to the social order in its various dimensions.
