There are three articles centered on the Lisp programming language, where Hofstadter first details the language itself, and then shows how it relates to Godel’s incompleteness theorem.
The title is an example of wordplay: it is an anagram of Mathematical Games, the title of Martin Gardner’s column that Hofstadter’s column succeeded in Scientific American.

* If you ask a mathematician, a mineralogist, a historian, or any other man of learning, what definite body of truths has been ascertained by his science, his answer will last as long as you are willing to listen. But if you put the same question to a philosopher, he will, if he is candid, have to confess that his study has not achieved positive results such as have been achieved by other sciences. It is true that this is partly accounted for by the fact that, as soon as definite knowledge concerning any subject becomes possible, this subject ceases to be called philosophy, and becomes a separate science.
o Ch. XV: The Value of Philosophy

Cassandra in Greek legend, you recall, was condemned to know the future but to be disbelieved when she foretold it. Hence the agony of foreknowledge combined with the impotence to do anything about it.

這段改篇自 2010 年 4 月 30 日的對話。
（CKY：我擔心我在公開試時，會只拿到 F 級成績。）
不會，除非你在校內模擬試的成績是 F。
公開試之前，最後一次校內考試是「模擬試」。一方面，它的考試範圍不會小於公開試。另一方面，校內試很可能會深於公開試：校內試題每次只由一位老師設計。如果剛巧那位老師的風格是「深」的話，整份卷的題目都會深。但是，公開試的試卷是由多人設計、多人核對的。即使深，也只會個別題目深，而不會所有題目深。
總括而言，大部分情況下，校內試比公開試「危險」。你公開試的成績，不會比校內試差。
（CKY：我的 A.Maths（附加數學）在校內試已經有 E（合格）。那即是我在公開試有機會拿 D？）
無錯。
