Here's one version, from Daniel Dennett:
> How to compose a successful critical commentary:
> 1. You should 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. You should list any points of agreement (especially if they are not matters of general or widespread agreement).
> 3. You should 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.
