Abstract

I believe that numbers and functions of analysis are not the arbitrary product of our mind; I think that they exist outside of ourselves, with the same character of necessity as the things of objective reality, and that we encounter, or discover them, and that we study them like physicists, chemists, zoologists, etc.
