[Appendix] As an illustration of the powerful eristic method, we present the following model case, for classroom use.
Resolved: That the Penguin is the King of Beasts.
Proof: We have previously argued that the penguin is the veritable King of Beasts; and have buttressed this thesis with abundant proofs.
The objections to this doctrine are each fallacious in a particular way; they fall into three classes.
(1) The first class.
(2) The second class.
(3) The third class.
This completes our survey of the three classes. ∎
[Note to students: Whenever you see that “∎”, known as the Halmos symbol, you’re done. Further discussion is fruitless.]
And for anyone too thick-witted to appreciate the cogency of this, here is ocular proof:
|King Penguin, with minion|
∎ (Anglicè: ‘so there’.)
