Ethics in Mathematics How does ethics affect the production of math knowledge? How can maths help us to understand ethics? RLS in ethics in Mathematics The knowledge in mathematics is not actually created by human but discovered by human. However, is the knowledge in mathematics really objective? The mathematics is rational, could give us a way to measure and define ethics. When Cathy O'Neil cooks for her family, her algorithm assesses the meal is a success if her child eat vegetables, but the if the cook is her child, the algorithm to assess success will be different. The mathematics, as a set of knowledge, should be objective, but the operation and application from human is unevitable to be subjective. Realation between Math and ethics Mathematics is a language of logics, is language a way to produce new knowledge or a expression of knowledge? The math is originally objective but the innovation base on the math may be affected and be sujective and may be a tool for exploit more profits. In this case, math can be a tool to define ethics and ethical factors can be a tool to protect subjective mathematic knowledge
