Clearly, attribution and citation are important in writing. Careful attribution helps you avoid unsophisticated repetition and offer instead sophisticated evaluation. From such an attributed claim, the reader may give less weight to the claim of error. In this case, you include with the attributed claim evidence disputing it. Citing sources is not an add-on to writing, but something as integral as diction, rhythm, or sequence.
Attribution also helps establish expert authority.
As a writer you will often use sources to establish an authoritative voice, to move the audience by impressing them, and to render yourself believable. Citing sources fully and honestly helps you do that. While use of the computer increased between 1955 and 1980, Isler found a method of physical analogies by which he could develop a scientific theory appropriate to structural art. His is a scientific theory of play, for all the laws of nature are obeyed. The Paraphrase A paraphrase is a close approximation of what a source has said, without using the exact wording.
