Well-known speeches; Wendell Berry--"People, Land, and Community"

I need to analyze a speech for a college English class. I already wrote a paper analyzing the first image on this page (right click to view the full image, it's stunning isn't it?) My thesis ran along the lines of "Whatever the photographer's intended message may have been, this photograph can be a powerful wake-up call to those who are not familiar with industrial agriculture" and I went from there, analyzing and explaining all of the visual elements as I could find. This was purely analysis, no research required.

Now I need find a speech to research and analyze. I'd like to find a good speech that talks about the values of community, sustainability, agrarianism, feminism, ecology etc. BUT I could just as easily analyze a "bad" speech that talks about the values of, say, industrial agriculture.

This speech must be popular enough that other people (respected academics, journalists, etc.) have already done analyses of their own about the speech. And of course it must utilize skillful rhetoric (I have to have something to analyze, this is English class after all!)

Wendell Berry's speech "People, Land, and Community" at the first E. F. Schumacher lecture series in 1981 certainly has beautiful rhetoric, comparing marriage to farming, but I will need to do some research and find out if I will have enough sources to draw on. In the meantime, I'd love to hear your suggestions.

It doesn't look like I'll find the required number/type of sources for Berry's speech.

On a whim, I Googled "abraham lincoln agriculture speech" and found a really interesting speech that Lincoln gave in Milwaukee.

Would Berry's Jefferson lecture work? I googled Wendell Berry critical analysis of speeches. I've always liked Berry.

Seems like he is getting "lifetime achievement oscars" as the mainstream DC politicos try to co-opt and understand him.
