Hi Bruno Marchal I believe that there are at least three attributes of numbers:

1) Are they true or false as in a numerical equation ? Does 2+ 2 = 4 ? True. 2) Do they physically exist or do they mentally inhere ? They inhere. You can't touch them. 3) Are they real or not ? Numbers are always real (in the philosophical sense).

How will you define "we" without accepting "2+2=4", given that IF we assume comp, "we" are defined by (L?ian) universal number and their relations with other universal numbers? Why do you keep an idealist conception of numbers, which contradicts your references to papers which use, as most texts in science, the independence and primitivity of elementary arithmetic? Or you remark was ironic? Bruno http://iridia.ulb.ac.be/~marchal/ -- You received this message because you are subscribed to the Google Groups "Everything List" group.
