This line by Kurt Vonnegut, one of my favorite writers, often gets quoted by would-be writers and literary types:
“Here is a lesson in creative writing. First rule: Do not use semicolons. They are transvestite hermaphrodites representing absolutely nothing. All they do is show you’ve been to college.”
This sort of exaggeratedly arbitrary, nose-thumbingly subjective opinion is exactly what we love in lovable writers, but it is also the exact sort of thing we should develop in ourselves, not mimic (or worse, throw as a “rule” at others when they fail to comply).
This quote is from the wonderful and hilarious “A Man Without a Country”, and the point of this edict is that it is in jest. One of the central themes of his work is questioning authority, in particular in thinking for yourself.
So it’s not about this particular rule, but that a proscription of any sort should be considered and most importantly, challenged.
