“He has been described as “an innkeeper who hated his guests, a philosopher, and poet who left no written record of his thought, a despiser of women who gave all he had to one, an aristocrat, a proletarian, a pagan, an arcadian, an atheist, a lover of beauty, and, inadvertently, the stepfather of domestic science in America.””
