Synopsis
"Human Life: Considered In Its Present Condition And Future Developments, Especially With Reference To Its Duration" by William Sweetser. This volume surveys the nature and worth of human life, arguing that life cannot be measured by years alone but by mental and moral activity. It traces competing theories of life, the concept of a universal vital force, and the perpetual diffusion and renewal of life across all forms, from infusoria to humans. Sweetser examines the duration of life, the prevalence of natural death, and the exceptional longevity observed in various species, as well as influences on longevity such as climate, diet, sleep, and temperance. It surveys historical searches for a panacea, alchemy, transfusion, and the role of science in extending life, while arguing that true protraction of life must come through human wisdom and healthful living. The text defends the progress of science, highlights the importance of intellect, virtue, family and friendship for well-being, and posits a forward-looking view: humanity’s destiny is upward progress, with life’s lengthening as a possible future achievement. The Introduction frames a consistent program for understanding life’s durations and aims: to harmonize knowledge, virtue, and health in the service of a longer, better life.
