I. The Line Verbatim

15) Ergo, if we truly judge that virtue is good, we will desire it.

Section Three: Positive Happiness or Appropriate Positive Feelings — its opening line.

II. Sterling’s Dated Elaboration

No dated elaboration located for this line specifically; its engine is Th7, whose dated defenses are recorded in the Th7 document. The gap is recorded as a finding, subject to revision.

III. Dependency Position

Derived, from line 14, per the Atomic Foundation — and the derivation marks the sharpest boundary in the skeleton. Line 14 closed the negative program: immunity secured, 2* discharged. Line 15 opens with the same words — “truly judge” — but points them forward: what clause (a) achieved as a terminus becomes a premise. Per the ratified Joint Two analysis, this is the promissory structure of the system in miniature: nothing in Section Two hinted that true judgment would produce anything beyond immunity; line 15 reveals it was also capital. Its immediate dependent is line 17, reached with Th16; line 17’s output is, in turn, exactly what clause (b)’s line 29 will cite.

IV. Synthesis

The Ergo’s engine is Th7 running in the legitimate direction. Everywhere in Section Two, the causal law appeared as the failure mechanism — false belief manufacturing irrational desire. Line 15 is the identical law fed a true input: judge truly that virtue is good, and by the biconditional bracket of Th7, the desire follows — not by instruction, resolution, or discipline layered on top of the judgment, but as what the judgment is. The system’s single causal mechanism thus needs no exception for the reformed agent; the machinery that produced every pathos now produces the one desire the framework endorses.

And it is the one safe desire — the engineering deserves stating. Under Th3, every desire is exposure: a stake in an outcome that can fail. The desire for virtue is the unique desire whose object, being an act of will inside Th6’s boundary (line 11), cannot be withheld by anything but the agent himself. Line 15 therefore does not reintroduce the vulnerability Section Two spent twelve lines eliminating; it installs the single desire that carries no exposure, which is why line 14’s immunity and line 15’s motivation coexist without tension. The agent is not left desireless and inert after the value strip — the quietist misreading dies here, three lines before Th25 finishes it off.

V. Where the Flow Goes Next

Th16 supplies the psychological law the chain needs next — achieved desire yields positive feeling — so that line 17 can convert correct judgment and correct will into appropriate positive feelings. Th16 is the next document, brief, as a basic but peripheral premise.
