Homework Help: How would the different schools of thought explain the statement '1+2=3'?

  1. Apr 5, 2012 #1
    This is a question on a past exam I'm trying to asnwer.

    So far I have, and I'm not sure if my understanding is correct yet:


    Consider if man-kind became extinct, the statement 1+2=3 will always be able to be recovered.


    3 is a consequence of the specific intepretation of to the rule of addition, applied to 1 and 2.


    The succesor of 1 is 2, so the successor 2 must be 3, and so 1+2=3.


    Under a model for a first order theory, a logical consquence of 1+2 is 3.
