qilorai decided to study the book Logical Labyrinth by Raymond Smullyan (with hopes of not losing my WHOLE left-hemisphere to this menopause)...
i am going to just type one of the puzzles per night, if anyone has thoughts to share, feel free!
and the following day i will post the next puzzle for that day, and the solution of the day before....
here is today's puzzle:
Edgar Abercrombie was an anthropologist who was particularly interested in the logic and sociology of "lying" and "truth telling". One day he decided to visit a cluster of islands where a lot of lying and truth-telling activity was going on! The first island of his visit was the Island of Knights and Knaves. (Knights always tell the truth; Knaves always lie)
PROBLEM 1.1 (a classic case): On the day of his arrival, Abercrombie came across three inhabitants, whom we will call A, B and C. He asked A: "Are you a knight or a knave?" A answered, but so indistinctly that Abercrombie could not understand what he said. He then asked B: "What did he say?" B replied: "He said that he is a knave." At this point, C piped up and said: "Don't believe that; it's a lie!"
Was C a knight or a knave?
