I am a great lover of Thoreau's prose, and this is a great photo.
If "hippie" means cutting yourself loose from the mainstream completely and living independently from others, however, Thoreau, who feasted at Emerson's table incessantly, never cut himself off far from the optimistic clergyman's swaddlings.
Reading biographies of Thoreau, one is impressed with how much HDT relied on Emerson's financial and moral support, launching into some of his greatest work while under the aegis of the older philosopher. Emerson even tried to find Thoreau publishers through Emersonian family connections.
Thoreau worked as a tutor for members of the Emerson family, as a "handyman" living in the Emerson home 1847-48, and, most famously, moved into a cabin of his own construction in 1854 ( on July 4th) which was located on land owned by Emerson.
Next to occasional land surveying and working in his own father's pencil factory, Thoreau stayed quite close to home and relied heavily on the financial support of his family and his "second father", Emerson.
The magnificent journals and "tour" books we possess of HDT's are the fruits of that relatively stable outer life. And thank God for Emerson, or we might not have Thoreau.
Inwardly, he may have been the first "hippie." He certainly declared principles along those lines. He was as "anti-Establishment" as one was likely to find in 1850 in the US.
Here's a fun definition to try Thoreau against:
