The Correspondence of Thomas Carlyle and Ralph Waldo Emerson 1834-1872, both volumes in one file

According to Wikipedia: "Thomas Carlyle (1795 - 1881) was a Scottish essayist, satirist, and historian, whose work was hugely influential during the Victorian era. Coming from a strict Calvinist family, Carlyle was expected by his parents to become a preacher, but while at the University of Edinburgh, he lost his Christian faith. Calvinist values, however, remained with him throughout his life. This combination of a religious temperament with loss of faith in traditional Christianity made Carlyle's work appealing to many Victorians who were grappling with scientific and political changes that threatened the traditional social order."
