- Introduction to Arithmetic
"Introduction to Arithmetic" was written by
Nicomachusalmost two thousand years ago, and contains both philosophical prose and very basic mathematical ideas. Nicomachus refers to Platoquite often, and wrote about how philosophycan only be possible if one knows enough maths. This is the only complete book of his that survived to our day. Nicomachus describes how natural numbersand basic mathematical ideas are eternal and unchanging, and in an incorporealrealm.
