The Empty Toll Booth, or, Be Your Own Lemming

Now that we've begun our head-long dash down the path of Knowledge Questions, stop and regroup a bit for Thursday.  Read this guide to Knowledge Issue Extraction, then read two articles from 3 Quarks Daily or Arts and Letters Daily (links to which are on the right under TOK Links) and write a post that contains a) a real-word situation; b) a weak knowledge issue; c) a strong knowledge issue from each article.  Be sure to indicate from which article each situation and KI comes.

You'll know it when you see it, right?  For next time, please find, share here, and explain one example for each of the following terms: consistent, inconsistent, valid, invalid, and ambiguous.  Your examples should either be published or overheard (no fair setting the stage).  If the latter you may use pseudonyms.

For tomorrow, toddle off to Oxford and work through this logic tutorial on consistency and validity.  Once on the site, follow the Tutorials link, then select Tutorial One.  Continue until you finish Exercise 1.4.  Having completed this, consider (in writing) how the skills this tutorial develops help you understand and tackle the puzzles and paradoxes from the previous post.

Logic--Huh! Good God! What is it good for?

Setting aside ontological arguments for the moment, let's begin to sharpen our logic skills.  For Tuesday, please tackle these logic puzzles.  Work patiently and with a pencil, reasoning out the consequences of each statement and, where appropriate, its speaker.  In your post examine the ways your thinking changed or developed to accommodate this task.  What was most difficult?  How did you arrive at the answers?  If you get angry at logic, take a break and read this.
