Exercise 10

Answer key for second sorites "Regarding trade and human rights:"

The second proposition in the key, "No country that imprisons its people for political reasons is a country that has respect for human rights", is a negative which should not be the case for either an Aristotelian or Goclenian sorite.

The last two propositions do not seem to follow the "All A is B, therefore no A is E" structure. China, if it's the "A", should be the subject of the last two propositions. See below from key:

"China is a country that imprisons people for political reasons"
"Therefore, we should not give special trade privileges to China."

I do see that one could convert the last proposition or the second proposition because they are E statements to try to structure it as Goclenian, but I'm getting tangled up. Could you please advise?

Exercise 12

"Regarding public schools". The answer key says it is a pure conditional sorites that denies the consequent. I do not find a "not" statement denying something.

Thank you for your help. My reward for getting through these last few chapters of TL II is to start your rhetoric book which looks great.
