Analyze the structure of the analogical arguments in the following passages, and evaluate them in terms of the six criteria that have been explained:

Suppose that someone tells me that he has had a tooth extracted without an anaesthetic, and I express my sympathy, and suppose that I am then asked, “How do you know that it hurt him?” I might reasonably reply, “Well, I know that it would hurt me. I have been to the dentist and know how painful it is to have a tooth stopped [filled] without an anaesthetic, let alone taken out. And he has the same sort of nervous system as I have. I infer, therefore, that in these conditions he felt considerable pain, just as I should myself.”

—Alfred J. Ayer, “One’s Knowledge of Other Minds,” Theoria , 1953
