Rules for writing (George Orwell, "Politics and the English language", 1946):

(1) Never use a metaphor, simile, or other figure of speech which you are used to seeing in print.

(2) Never use a long word where a short one will do.

(3) If it is possible to cut a word out, always cut it out.

(4) Never use the passive where you can use the active.

(5) Never use a foreign phrase, a scientific word, or jargon word if you can think of an everyday English equivalent.

(6) Break any of these rules sooner than say anything outright barbarous.

Rules for criticism (Daniel Dennett, "Intuition Pumps and Other Tools for Thinking", 2013):

(1) Attempt to re-express your target's position so clearly, vividly, and fairly that your target says, "Thanks, I wish I'd thought of putting it that way."

(2) List any points of agreement (especially if they are note matters of general or widespread agreement).

(3) Mention anything you have learned from your target.

(4) Only then are you permitted to say so much as a word of rebuttal or criticism.
