DỊCH SANG TIẾNG VIỆT ( SỬ DỤNG CÂU VÀ DIỄN ĐẠT THẬT HAY BẰNG TIẾNG VIỆT NHÉ, ĐỪNG VẤP LÀ ĐƯỢC) "Uncle Tom" is now a pejorative...we must reclaim the absolute hero status of this very positive literary character. Of course, the only way to do that is encourage folks to READ THE BOOK! So, folks, READ THE BOOK. You must be aware that this is a book of its time. The language takes a minute to get used to, but this is a riveting read and essentially a first-hand account of what slavery was through the eyes of a witness living at the time. Critiques by many say Stowe failed to fully humanize slaves as unique individuals; she stereotypes and reduces them to stereotypical behaviors and speech--all true. She does this with most of the characters in the book and she imbues others with preternatural wisdom, charm, and grace (e.g., Eva). THAT's LITERATURE, folks. Yet, the message in such urgently dire circumstances, from someone so deeply committed, must not be watered down, subtle or duplicitous! Stowe does use plain language (so to speak) and readily available images to which the folks of the time could relate. That does mean a kind of, dumbing-down, and the use of a short-hand in order to convey a message that, for the time, needed to be heard. Amazingly, UCT sold 300,000 copies in its first year...can you imagine! People were being reached with Stowe's message. Stowe wrote 30 other novels, a feat (as mother, wife, author, et al roles) I find extraordinary and she was fighting for woman's rights also. This is a major literary achievement. Must read for all Americans.
