The Mathematical Experience by Philip J. Davis and Reuben Hersh talks about the different ways of viewing mathematics, including this Platonic idea of it existing "out there". Another poster noted a quote--which I also think is from that book--about many mathematicians being Platonists on the weekend. It's a beautifully written book. I've read it twice, and just thinking about it makes me want to read it again. https://en.wikipedia.org/wiki/The_Mathematical_Experience https://en.wikipedia.org/wiki/The_Mathematical_Experience
