Looking-Glass Logic<br />
true. Then, by Condition Two, he claims that he doesn't believe the<br />
statement. Hence, again by Condition One, he must believe that he<br />
doesn't believe the statement.<br />
"Anyhow," continued Humpty Dumpty, "I'm giving you too<br />
many hints! Let me finish my list of conditions, and then you should<br />
deduce the key to the entire mystery.<br />
"Condition Three—Given any true statement, he (the Looking-<br />
Glass logician) always claims that he believes the statement.<br />
"Condition Four—If a Looking-Glass logician believes something,<br />
then he cannot also believe its opposite.<br />
"Condition Five—Given any statement, a Looking-Glass logician<br />
either believes the statement or he believes its opposite.<br />
"And that," concluded Humpty Dumpty proudly, "is the entire<br />
list of conditions. From these you should be able to infer just which<br />
statements a Looking-Glass logician believes to be true and just<br />
which ones he believes to be false. I will now ask you some questions<br />
to test your understanding.<br />
"Question One—Suppose a Looking-Glass logician believes that the<br />
Red King is asleep. Does he believe that the Red King is dreaming<br />
of you, or doesn't he?"<br />
"Now, how could I possibly know that?" cried <strong>Alice</strong>.<br />
"You should," replied Humpty Dumpty. "The answer follows<br />
directly from the conditions, but I won't tell you how until later.<br />
Meanwhile, let me ask you this:<br />
"Question Two—Suppose a Looking-Glass logician believes that<br />
either the Red King or the Red Queen is asleep. Does it follow that<br />
he believes that the Red Queen is asleep?"<br />
"Why should it?" replied <strong>Alice</strong>.<br />
"It does," said Humpty Dumpty, "but I won't tell you why till<br />
later. Meanwhile, try this:<br />
"Question Three—Suppose he (the Looking-Glass logician) believes<br />
that the Red King is asleep. Does he necessarily believe that the Red<br />
Queen is asleep?"<br />
"Now, why in the world should he?" asked <strong>Alice</strong>, more bewildered<br />
than ever.<br />
"Good question," replied Humpty Dumpty, "and we'll discuss it<br />
later. Meanwhile, try this:<br />
