Classifying disagreements

Paul Graham has an interesting essay about the type of disagreements commentors make on blogs (and elsewhere). Here is his list:

  1. DH0: Name Calling (“The author is a self-important dilettante”)
  2. DH1: Ad Hominem (“Of course he would say that, he is a Senator”)
  3. DH2: Responding to Tone (“I can’t believe that the author dismisses intelligent design in such a cavalier manner”)
  4. DH3: Contradiction (“I can’t believe that the author dismisses intelligent design in such a cavalier manner. Intelligent design is a respected scientific theory.”)
  5. DH4: Counterargument
  6. DH5: Refutation
  7. DH6: Refuting the Central Point

Personally when writing on the blog I try to keep to DH3 or above but I’m sure someone will find examples where I have strayed.
