The eccentricities of logic in the English language are truly fascinating, especially the fact that we abide by weird stylistic rules because they are universally understood, not because they necessarily make sense. Some choices have been made by use, others determined by print, others by the dominance of certain ethnic groups, still others (like the letter aitch) by rationality. The New York Times posted an article today on why we capitalize the letter "I". If you're still interested, Daniel Heller-Roazen wrote a great book on the forgetting of language.
