For instance, one of the questions we discussed was, “Do numbers really exist independently, or are they just an idea that humans invented?” In other words, is “two” really just an idea that people have? If there were no people, would there still be “two”? Guess what? I got an “A” in this course and the next year, Professor Davis asked me if I wanted a job as a teaching assistant. I was flattered, but I said, “No, thanks,” I was afraid that my poor abilities in math would be discovered.
