A while back, I was careless. I wrote, “In a campaign biography of James G. Blaine, the Republican candidate for president in 1884, for example, [Russell] Conwell refers approvingly to [his following] ‘the paths of exploration and speculation so fearlessly trodden by Darwin, by Huxley, by Tyndall, and by other living scientists of the radical and advanced type.’” Let’s not worry about who Conwell and Blaine were or why I was bothering to discuss them at the Science League of America—you can read the earlier post if you’re interested. The present point is just that those weren’t Conwell’s words: rather, he was quoting Blaine’s eulogy for James A. Garfield (1831–1881; right), the twentieth president of the United States, assassinated in the first year of his presidency. Whoops! But at least it gives me a chance to write about Garfield now.
