Style

The reminders in the approach to style chapter of The Elements of Style are not rules, they are simply the opinion of a writer. There are good and bad points present in anyone's opinion. It is also a rather broad description of the way one should write. There are many different kinds of writing-research, persuasive, technical, creative, etc. where these reminders would not be relevant.
For example, reminder number 17 to not inject one's opinion (p.70) is ill-advised for a writer who has an editorial column in the newspaper or for someone who is writing a persuasive piece. Someone who is writing poetry might find it difficult to do so when they are not supposed to use fancy words (p.76).
There are good points as well. Writing in a way that comes naturally (p.70) is something every writer should strive for. Each has his own unique style. If the work an author has crafted is awkward to him, it will be unusual to the reader. Making sure the reader knows who is speaking (p.76) is also a valid reminder. Confusion in a story is never welcome.
I have the most trouble accepting reminders such as avoid using fancy words (p.76) and prefer the standard to the offbeat. Writing is an art. It is a masterpiece woven from one's heart. "Fancy words" add to the beauty. Not many people view a plain piece of art with little color and detail as stunning and breathtaking. A piece of literature, whether it is a book or an essay, should provoke some sense of awe in a reader. A less standard way of writing pushes the envelope for a deeper level of reading pleasure. After all, society has not grown from people who think everything should stay the same. Just as technology and industry have been developed, writing should also flourish and sprout new buds. What would this author who wrote these reminders have said to Mark Twain in his era? Would he have said you cannot write that way because it just doesn't follow the standards? I say offbeat is the way to go!
