I think I recognise that quote from a poster with a different handle, don't I?
Here's what I remember thinking last time.
Was Thoreau a wise man?
Or merely a condescending one, as the quote suggests, and in want of a mirror?
Personally, I prefer my heroes to be humble. Arrogance is not a persuasive pulpit.
Or put another way, if a person was chief of the association of village idiots, would they not presume themselves to be the hero-patriot identified by Thoreau?
I recommend searching for a new author with a little more self-awareness.
