Why did Edgar Allan Poe dislike transcendentalists so much?

Taste kicking in articulo mortis." Poe portrayed himself as an enemy of the Transcendentalists at least to the extent of often sneering at them. He called Emerson "over-rated" and remarked on the lack of basic logic and rationality in his philosophy.

Poe's utter dislike of Transcendentalism was no secret (he once took a swipe at Nathaniel Hawthorne, who he otherwise respected, simply for living in Concord, Massachusetts - the seat of the movement), and his particular disgust with Emerson was equally well-known. Poe chided the Concord Sage for writing that was purposely difficult to understand - "mysticism for mysticism's sake," as Poe referred to it. Poe also identified (and he was a bit right) that Emerson was "little more than a respectful imitation of [Thomas] Carlyle."
