Second and third intro logic lecture

I have been pretty surprised to find that over four hundred people not doing my elementary first year logic course for philosophers have downloaded the slides for the first lecture. So I’ve decided to keep uploading the lecture slides here for a while — though after a time-lag —  so there will be roughly two more lectures every week for a few weeks, or at least while download rates make it seem worthwhile. They aren’t very exciting: but they do serve to keep the live show basically on message! (The slides as I use them of course reveal bullet points one at a time, but I’ve suppressed that in these early lectures.)

These next two lectures are the rest of my three introductory lectures before we get down to work on PL:

  1. Lecture 2 (The counterexample technique)
  2. Lecture 3 (Proofs: Divide and Rule)

If you want a bit more by way of elementary introduction at this level, read the first six chapters of my Intro. to Formal Logic (utterly splendid and amazingly cheap, it goes without saying: buy it — or at least ensure that your uni. library has the 2009 reprint)!

Comments and corrections welcome, of course.

  1. Concur with enthusiasm the recommendation to purchase the 2009 edition of IFL. I do urge caution in ordering the book, though. The Cambridge web sites (UK, USA) display the 2003 edition only, and the same is true of Amazon and Barnes & Noble. There are individuals at CUP who are aware of the updated text, but it’s worth taking the time to ensure your purchase is as you expect.

    1. Let me clarify. A new “edition” in the official publishers’ sense would have a new ISBN, new marketing campaigns, etc. There hasn’t been a new edition in that official sense, so e.g. the publishers website and Amazon will still (correctly) say ‘Published 2003’.

      However, when the stock of the large first print run was almost exhausted I supplied a new corrected PDF for the reprint, and the few remaining copies of the first printing were pulped. That was over eighteen months ago, so the publishers would now supply you or a bookshop with the corrected reprint version, likewise for Amazon or major book stores.

      So you’ll just really need to double-check if you are buying second-hand, or from a shop with a small turn-over which might have had an old copy lurking for a few years.
