>The Affordance Flag

利 does not report what will happen. It reports what the configuration can carry.

利 (lì) fires one hundred and seventeen times across the canonical text — the second most frequent verdict term in the entire system, behind only 吉 (jí, auspicious). English translations cast it as "advantageous," "favorable," or "it furthers." None of those is wrong, exactly. But they do a quiet kind of damage: they let 利 dissolve into the same register as 吉 — diffuse good fortune, a warm sense that things will go well.

They will not necessarily go well. 利 is not an outcome opcode. It is an affordance opcode. It describes the relation between a configuration and a class of action — what the situation supports, not what the situation delivers.

The first structural fact a reader should notice: 利 almost never appears alone. It carries an operand — a complement naming the action class it scopes. The three most common forms:

• 利涉大川 (lì shè dà chuān) — crossing the great river is supported
• 利見大人 (lì jiàn dà rén) — alignment with authority is supported
• 利有攸往 (lì yǒu yōu wǎng) — forward movement is supported

These are not stylistic variants. They are structurally required. 利 does not describe a state of the world; it describes a relation between the configuration and a kind of move. Strip the complement and the statement is incomplete — a flag with no field, an operator with nothing to operate on.

The hardest exhibit to argue with is the judgment of Hexagram 6 (䷅ 訟 sòng, Conflict): 利見大人，不利涉大川 — "Advantageous to see the great person. Not advantageous to cross the great river." Two affordances in one breath, one positive, one negative, for two different action classes. The configuration supports hierarchical alignment and refuses to support high-risk crossing, simultaneously. If 利 meant general good fortune, that line would be a contradiction. It isn't. It is precise: this kind of move, yes; that kind, no.

Modern readers collapse three distinct measurements into one warm blur. The text keeps them apart. 利 evaluates affordance: which action-path the configuration supports. 无咎 (wú jiù) evaluates process: whether the handling came out clean. 吉 (jí) evaluates outcome: whether the configuration resolves favorably.

So when a reader meets 利涉大川 and hears "it will go well if you cross the river," they have shorted all three gauges together. The structural reading holds them apart: the configuration makes river-crossing viable (利). Whether it goes well still depends on execution and timing. The full chain the book encodes runs 利 (affordance) → action → 无咎 (corrective fit) → 吉 (favorable resolution) — and every joint is independent. The chain can snap anywhere. 利 without 吉: the affordance was real, the execution failed. 无咎 without 吉: clean process, sour result. 利 is necessary for 吉. It is nowhere near sufficient.

English grammar quietly miscasts the subject. "It is advantageous to cross the great river" installs the reader as the implied agent — you are being advised, the oracle is handing you an instruction. The structural reading reverses it: "crossing the great river is the kind of move this situation can carry." The configuration is the subject. 利 is a property of the field, not counsel to a person.

The boundary conditions make this unmistakable. 無不利 (wú bù lì, "nothing not advantageous") appears thirteen times: a configuration where every action class is viable — not a promise that all will go well, but a report that the situation imposes no structural constraint on movement. Its mirror, 無攸利 (wú yōu lì, "nothing advantageous"), names the opposite floor: no path is supported at all. Neither is advice. Both are system-state readouts.

The most common 利 compound in the corpus is 利貞 (lì zhēn) — thirty-six occurrences, usually Englished as "perseverance furthers." That misses the wiring. 貞 (zhēn) is not a virtue but a mode of action: holding-to, sustaining, maintaining the position. So 利貞 means the configuration affords the holding-fast — the action class supported is specifically the constancy-type move, not bold crossing, not seeking authority, but the quiet discipline of keeping station.

Which makes explicit what is implicit everywhere 利 fires: the affordance is always scoped to the complement. 利涉大川 is not "everything is supported" — it is crossing is supported. 利見大人 is not "go forth boldly" — it is alignment is supported. The complement is the scope, and without the scope the flag means nothing.

The edge case that proves the operator: Hexagram 26, line 1 (䷙ 大畜 dà chù, Great Accumulation) — 有厲，利已: "There is danger. Advantageous to stop." The complement 已 (yǐ) means to desist, to cease. The configuration affords stopping — not moving, not crossing, not seeking, but stopping. If 利 were a push to act, this line would jam. It doesn't. It is the same operator pointed at a different action class. The situation can carry cessation. That is what is supported here.

利 names the move, never the result — read the flag, then read the field it points at.
