Good writing can be learned. Language is a science, with rules and laws. Start with a strong foundation, and you can improve your writing. Here’s how:
Learn grammar and punctuation. Only when you have a firm grasp on these pillars of language can you begin to play with them. You’ll learn that these rules can be bent, but they cannot be broken if you want to be an effective writer. Start with Strunk and White.
Study logic. Finding something illogical is not an opinion or an insult; it’s a fact. Deeming a statement illogical is not a subjective decision. It is the result of applying the rules of logic and determining that the statement does not fit. Knowing how to identify and employ concepts like red herring, slippery slope and deductive reasoning will make your arguments stronger.
