The Strenuous Life (Speech, 1899)
Theodore Roosevelt
Roosevelt's call to "dare mighty things" counters the prevailing comfort of the industrial era's newfound ease. At the brink of the 20th century, technological advances promised a life of convenience, yet he warned against a life devoid of challenge. The grey twilight he scorns is a metaphor for a life untested, stagnant and devoid of the vibrancy that comes from risk. This was a rallying cry for a nation, not just individuals, to strive for greatness amid uncertainty.
