Beyond his own case, Cornaro generalised the sober life into a universal rule: that strict moderation conserves the body’s powers and so lengthens any life, a “divine medicine” available to all. It is classified as mechanism_only because the universal claim rests on a posited principle (that life is preserved by spending the body’s powers slowly through abstemious living) rather than on any measured outcome across people. It is recorded as untested: the generalisation from a single self-reported case to a universal law of longevity was asserted, not demonstrated, and no population study supported it. The same conserve-the-vital-power logic reappears, formalised, in Hufeland’s macrobiotics two and a half centuries later, where it is recorded in this archive as a mechanism-only proposition as well.
