A few words to describe Thoreau after reading these journals:
Naturalist
Philosopher
Idealist
Anti-Christianity-ist
Theologian
Mystic
Narcissist
Transcendentalist
Isolationist
Misanthrope
Moralist
Funny that he would probably recoil at being reduced to labels, but that they can so easily be applied to him seems appropriate for someone so self-consciuosly keen on paradoxes.
Some standout quotations/excerpts:
Undated, 1850: God prefers that you approach him thoughtful, not penitent, though you are the chief of sinners. It is only by forgetting yourself that you drawn near to him.
June, 1850: Men talk about Bible miracles because there is no miracle in their lives. Cease to gnaw that crust. There is ripe fruit over your head.
Undated, 1850: As to conforming outwardly, and living your own life inwardly, I have not a very high opinion of that course.
Jan. 2, 1853: God exhibits himself to the walker in a frosted bush today sa much as in a buring one to Moses of old.
Jan. 3, 1853: I love Nature partly because she is not man, but a retreat from him.
June 5, 1853: The New-Englander is a pagan suckled in a creed outworn.
Aug. 7, 1854: How can we expect a harvest of thought who have not had a seed-time of character?
Sept. 21, 1854: I sometimes seem to myself to owe all my little success, all for which men commend me, to my vices. I am perhaps more willful than others and make enormous sacrifices, even of others' happiness, it may be, to gain my ends. It would seem even as if nothing good could be accomplished without some vice in it.
And on, and on, and on, really. So many big ideas and quotable quotes in here. Yes, hypocrisy, idealism, and absolutism run through the whole lot of it, but Thoreau seems at least to be aware that such things are paradoxically both right and wrong at the same time.
And a note on this particular text: Surprisingly readable print edition from Dover Publications--one of the few (the only?!) I've encountered.
