Meaning
Isosceles names triangles with two equal sides, but in the political chapters it gathers several unequal social positions. Artisans, soldiers, and convicts are not interchangeable groups merely because the narrator places them within an acute-angled lower order. Rebel describes a relation to authority, not a geometrical species. Some Isosceles oppose the Circles; others enforce their commands.
Use in the book
The first history of rebellion in §323 is a theory of leadership removal. More intelligent or reformable figures can be promoted, confined, or executed; their followers are left without plans. Paid members of their own class then attack them, or the rulers foment mutual distrust. The narrator presents the repeated outcome as evidence of the poor's defects. The account simultaneously provides evidence of an institution deliberately producing the conditions in which the poor fail.
Colour alters this pattern by making practical competence less dependent on elite education. The Isosceles classes can challenge the need to surrender educational specimens and question aristocratic intellectual monopolies. Their equality claims are not wholly dismissed even by their adversary. This admission matters because it prevents the political history from resting solely on the narrator's bodily insults. He describes a change in capacities that his rigid class language cannot entirely contain.
Pantocyclus's decisive manoeuvre separates artisans from those below them. Men expecting admission to the Regular class, or hoping for it for their children, are asked to fear universal equality as a loss of future distinction. The prospect of mobility becomes an inducement to abandon fellow insurgents. The artisans open their ranks, following the Regular classes, and permit the attack upon the soldiers. Hierarchy survives by making its aspirants act as its auxiliaries.
The guards at the exits sharpen the contradiction. These Convicts are drawn from the very population whose numerical predominance Pantocyclus has made alarming. Their bodies are useful when they seal the hall, while similar bodies inside it become a “rabble” blamed for fatal panic. Function changes moral description. The tale exposes less a uniform character of the Isosceles than the ruler's capacity to assign the same stigmatized class several incompatible roles.
Finally, the artisans' cooperation does not purchase safety. They are subsequently “spared but decimated.” Conditional solidarity with the rulers earns a reduced form of collective killing, not secure recognition. The event makes bodily classification politically powerful without making it an adequate explanation of motive, allegiance, or desert.
Places to read
In this edition
Notes 91 and 1022 explain the educational tribute and the strict punitive sense of decimated. The modern commentary criticizes the narrator's population language; the article likewise treats Criminal Classes as the regime's classification, not a demonstrated moral identity of everyone so labelled.
the greatest number (contextual phrase)
Exact wording: “the greatest number” (§1023).
Pantocyclus equates the greatest number with the Criminal Classes and converts a possible democratic justification into an alarm. The modern annotation connects the wording with the utilitarian language of the greatest happiness of the greatest number, already invoked in §723. In this speech, however, numbers establish a threat rather than a claim to welfare. The argument relies on the ruler’s prior classification of an entire population as criminal; it does not demonstrate each person’s criminal act. Artisans are encouraged to identify with the honour they hope to acquire rather than with the numerical majority to which they belong. The phrase therefore marks a change of political perspective: counting people can expose exclusion, or it can make their abundance a reason to suppress them.

spared but decimated (contextual phrase)
Exact wording: “spared but decimated” (§1023).
The conjunction permits the narrator to preserve a claim of mercy while reporting collective killing. The modern note reads decimated in its strict punitive sense: one in ten put to death. Most of the Working Men survive, but those selected do not, and the group’s cooperation with the Circles offers no immunity. Spared is comparative, measured against the complete destruction of another crowd rather than against an ordinary right to live. The phrase condenses the moral arithmetic of the regime: a smaller proportion killed can be presented as clemency. It also exposes the inadequacy of treating the suppressed movement as one undifferentiated population. Artisans receive a different punishment from soldiers, but the distinction remains within a policy of coercive reduction.
