Read Chapter 5 of Artificial Minds, by Stan Franklin. I would recommend reading at least this one by Monday.
Read the article Computing Machinery and Intelligence, by Alan Turing (Chapter 2 of Mind Design II).
Read the article A coffeehouse conversation on the Turing Test and the Post Scriptum, by Douglas Hofstadter, which I will pass out in class on Monday.
Read the article Minds, Brains, and Programs, by John Searle (Chapter 7 of Mind Design II).
Be prepared to answer a few brief questions about these readings when you come to class on Thursday.
