Excellent work! Introduction The Lord of the Rings, by J.R.R. Tolkien, has been called by some one of the greatest books of all time and has recently earned the claim of "greatest book of the 20th century" in a poll by Britain's Channel 4 (O'hehir). Yet at the same time scholars have often dismissed The Lord of the Rings as a fanciful children's story. While the validity of either claim can be equally well disputed, the The Lord of the Rings and related works by Tolkien nevertheless embody a very clear and consistent set of ethical themes.
