"Paradise (to be) Regained" by Henry David Thoreau is an essay published in 1843. Written as a review of John Adolphus Etzler's technological utopian manifesto, the essay examines wildly ambitious dreams of using machinery to eliminate human labor and transform Earth into paradise. Through extensive excerpts and measured commentary, Thoreau uses Etzler's extreme vision to critique humanity's faith in technology over self-improvement, ultimately arguing that true progress requires developing inner discipline before harnessing nature's forces.
