How Dickenson's poem is "fresh"

Dickenson does not use flashy words to get her point across in her poem.  Instead she focuses on tone and diction.  For instance, the phrase "truth it circuit lies", or telling it "slant", most words or phrases in her poem have a prominent "s" sound.  This "s" sound reminds me of a snake, or something sneaky, basically two phased.  That is what Dickenson's poem is.  She is telling her reader to tell the truth, but to tell it slant. When reading it out loud it sounds like a riddle one would hear in a storybook, sweet and straight forward in some lines, and in others more devious. It is fresh because her phrasing is simple, but the content is what makes it so.
