The relationship between mathematics and morality is easy to think about but hard to understand. Suppose Jane sees five people drowning on one side of a lake and one person drowning on the other side. There are life-preservers on both sides of the lake. She can either save the five or the one, but not both; she clearly needs to save the five. This is a simple example of the use of mathematics to make a moral decision – five is greater than one, so Jane should save the five.
