    "title": "On Tranquillity of Mind, Plutarch",
    "author": "Plutarch",
    "date": "late 1st to early 2nd century CE; internal order uncertain",
    "summary": "On Tranquillity of Mind observes character in action and tests moral rules against concrete situations.",
    "learning": "To read On Tranquillity of Mind, isolate the decisive action, distinguish character from fortune, then compare its consequence with that of a neighboring course of conduct.",
    "long_summary": "The essay connects philosophical examination with ordinary actions, relationships, and habits in which character becomes visible.\n\nCanonical identity follows the critical Greek CTS divisions. The historical English translation and AI-generated French remain distinct, labeled manifestations. Tranquillity depends less on changed fortune than on attention able to inhabit one's own share without coveting every other one.",
    "historical_context": "The corpus manifests do not yet establish the precise place and circumstances of composition. The images below document the author’s world or the text’s transmission. They do not claim to show the exact scene of writing.",

        "science": "Computing, genetics, climate science, cosmology, and medical imaging produce growing data and international collaboration.",
        "medicine": "CT, MRI, transplantation, vaccines, and intensive care advance; the AIDS epidemic exposes both medical capacity and its limits.",
        "transport": "Cars, high-speed rail, metros, aircraft, and containers globalize people and goods.",
        "agriculture": "Machinery, chemical inputs, breeding, and cold chains support high yields with increasingly debated social and environmental costs.",
        "communication": "Fixed telephones, fax, television, radio, and newspapers predominate. Email and computer networks remain mainly professional or academic.",
        "clothing": "Loose suits, jeans, trainers, women’s power suits, sportswear, and urban subcultures create highly varied silhouettes."
