What's the difference between i.e. and e.g.?
"Enlightenment rationalist and skeptic," especially in reference to any of the French Encyclopædists, often disparaging (when used by believers), 1774, from French philosophe, literally "philosopher" (see philosopher). Usually italicized in English, but nativized by Peter Gay ("The Enlightenment," 1966) and others. Also philosophist (1798).
