from "What is an Arminian"
John Wesley2. The more unintelligible the word is, the better it answers the purpose. Those on whom it is fixed know not what to do: Not understanding what it means, they cannot tell what defence to make, or how to clear themselves from the charge. And it is not easy to remove the prejudice which others have imbibed, who know no more of it, than that it is "something very bad," if not "all that is bad!"
The effect of labeling is not to identify, but to categorize without benefit of appeal. In Wesley's time it was "Arminian" now it is "Democrat," "Republican," "Liberal," "progressive," "Conservative," "Ultramontane." These are useful, much as the word "weed" is useful in dealing with whatever plant, no matter how native and how beautiful that creeps into the monoculture of the American front yard. A label is a deadly device, serving not so much to identify as to categorize and dismiss. And a label admits of no reprieve, because you have to know what so-and-so means when he says "Liberal" to know whether or not the shoe fits, and if it doesn't how one might address the error.
There are very good reasons for disliking labels even for those of us who are at heart essentialists.
