The original material

Somewhere, many of us got the idea that simplicity in writing is a vice- that the long word is better than the short word, that the complex phrase is superior to the simple one.  The misconception is that to write simply is to be simple minded.  (Ballenger, Bruce.  The Curious Researcher.  New York, Allyn and Bacon, 1994. p.184.)

Explanation

Direct Copying

There is an idea out there that simplicity in writing is a vice-- that the long word is better than the short one, that the complex phrase is superior to the simple one.  The misconception is that to write simply is to be simple minded.

Most of the first sentence and the entire second sentence are copied directly from Ballenger with no quotation marks and no citation.

Paraphrasing

Many of us have the idea that simplicity in writing and speaking is a vice-that long words are better than short words, and that complex phrases are superior to simple ones.  The idea is that writing  simply shows means you are simple minded.

A few words are re-arranged and a few are substituted, but the idea and order of development is Ballenger's who is not cited.

Theft of an Idea

Simplicity in writing is not a fault.  The short word is better than the long word; the simple phrase is better than the more complex one.  It is an error to think that one is simple minded because one writes simply.

The ideas are put in someone else's words, but they imply that they are the new author's rather than Ballenger's  since Ballenger is not cited.
