Cathy,
I'm one of the Peircean unwashed and hence appreciate the attempt at a simple example. Could you say a bit more about how this example illuminates or exemplifies the notion of Thirdness? I'm still a bit confused. After all, couldn't I say more about GIVINGEVENT001, e.g., (date GIVINGEVENT001 D), (eventOccursAt GIVINGEVENT001 E), etc,, and wouldn't this then involve an implicit quartic, quintic, etc. relation of identity? So why does this demonstrate Thirdness as opposed to, say, Fourthness or Fifthness or whatever?
best,
Mike Pool
