The Elements of Style travels the decades without showing a single wrinkle. What impressed me most is the attention to the reader, here and there hinting at the "contract" between writers and their readers: "you must sympathize with the reader's plight".
A final admonition to all writers aims at being truthful: "never seek to know the reader's wants [...] glance at the Trend Machine and you are as good as dead, although you may make a nice living."
No one can write decently who is distrustful and untrue.
An anonymous once remarked, "Writing is an act of faith, not a trick of grammar." The Elements of Style says that on every page.
