Introduction: Moments of Enlightenment GPT-4: There are different ways to divide the Gettysburg Address into sentences, depending on how one punctu- ates the text and whether one follows the original drafts or the versions that Abraham Lincoln delivered or later revised. However, one possible way to identify the fifth sentence of the speech is to use the Bliss Copy, which is the most widely reproduced and authoritative version of the address, and to count the sentences as follows: 1. Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Lib- erty, and dedicated to the proposition that all men are created equal. 2. Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. 3. We are met on a great battle-field of that war. 4. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. 5. It is altogether fitting and proper that we should do this. Therefore, the fifth sentence of the Gettysburg Address, according to this method, is: It is altogether fitting and proper that we should do this. Suddenly, GPT-4 seems to actually understand how counting works, and can methodically apply its knowledge to deduce the right answer. It seems like GPT-4 knows how to count Lin- coln’s sentences. It seems like it’s now an expert on the Gettys- burg Address. (Did you know that the “Bliss Copy” is the most “authoritative version” of the speech? I didn’t.) 15
