Identifying right with the good-for enables democratic liquidation of parts

Evidence

A conception of law which identifies what is right with the notion of what is good for—for the individual, or the family, or the people, or the largest number—becomes inevitable once the absolute and transcendent measurements of religion or the law of nature have lost their authority. And this predicament is by no means solved if the unit to which the “good for” applies is as large as mankind itself. For it is quite conceivable, and even within the realm of practical political possibilities, that one fine day a highly organized and mechanized humanity will conclude quite democratically—namely by majority decision—that for humanity as a whole it would be better to liquidate certain parts thereof. — Hannah Arendt, The Origins of Totalitarianism, 729

Categorization

• DEEPTHINKING: A dense, paradigm-level mechanism: once transcendent standards collapse, any ‘good for’ framing — even humanity-wide — authorizes elimination of parts by democratic majority. Resists one-sentence summary.
• XREF: Connects to necropolitics/biopolitics vocabulary the Islamophobia field builds on; also echoes the modern bureaucratic rationality theme.
• QUESTION: Worth chasing: does the ‘liquidate parts for the whole’ logic structurally prefigure race-based exclusion in modern states?
