It's taken me a bit longer than expected to get the Philosophy site organised behind the scenes so you might have noticed that there hasn't been much in the way of new content recently. I think these difficulties have largely been resolved now and from here on in I aim to post one new article each week and send out a newsletter every two weeks.
This week's article continues the introduction to Logic and can be found by following the link below:
The Valid Argument Form - if P then Q, not-Q therefore not-P.
Introducing negation into our arguments can throw up some surprising and amusing problems. Consider: If Socrates is a man then Socrates is mortal. Socrates is not mortal therefore Socrates is not a man.
If you have any questions arising from the article or if you're interested in discussions about any other matters philosophical you can visit the Philosophy Discussion Forum at
Feel free to pass on this newsletter to anyone you think might be interested and I hope to meet you in the Forum sometime or hear from you via the comments box on my bio page.
