Some more thoughts that I hope will bring me a step closer to this paper ...
I should have my notes with me as I write this. I don't--they're at home. But perhaps this is better. Writing without them may prompt a thought I didn't have as I was writing them.
When we compare Pasteur's laboratory notebooks with his published work, I believe the pattern is clear. It's not original--Gerald Geison makes the point firmly--but its application to rhetoric, and specifically to Burke's view of science and rhetoric, should be. I don't know yet whether I should limit myself to Pasteur. Research on Lavoisier leads to a similar conclusion, although I'm not sure Lavoisier had quite the rhetorical talents Pasteur did. In any case, it's absolutely clear that when we read a journal article, we're not getting an unbiased description of "the real world out there"; what we see is filtered through the scientist's rhetorical choices.
