'Hallucination': Hospital Ecologies in COVID's Epistemic Instability.

Historians and ethnographers have described biomedicine as a modernist project that imagines accumulating ever-more stable knowledge over time. This project broke down in heavily hit hospitals at the onset of the COVID-19 pandemic in the U.S., when bureaucratic, physical and knowledge structures collapsed. A combination of terror, a partially characterized disease entity and clinicians' inability to operate without disease models drove them to draw on rapidly changing and contradictory information via social media, changing medical practice minute-to-minute. The result was a unique form of knowing described as "hallucination": a hyperreal, unstable ecology of imagined viral particles distributed in physical spaces, transforming with each text message and tweet. The nature, experience and practice of this ecology sheds light on what happens when instability comes to otherwise stable places.

Toward a sociology of finitude: life, death, and the question of limits.

Progressing beyond the given has been a key modern tendency. Yet modern societies are currently facing the problem of how to put limits on progress, expansion, and growth, live within them, and preserve (rather than transcend) the present. Drawing on economic sociology scholarship on valuation and morality in economic life, this article develops and applies the term economization to analyze the enactment of limits on progress. The question of end-of-life care-when to stop medical efforts to prolong life, postpone death, and advance the scientific frontier-serves as an illustrative empirical case that sheds light on limit-setting in general. My analysis of this case combines historical, ethnographic, and in-depth interview data on US palliative care clinicians, who specialize in making life-and-death decisions in acute care hospitals.
