The purpose of education is to learn to tell the truth, and mathematics—if taught for its own sake—promotes this end by helping students to sharpen their intuition, to learn to reason better, to recognize valid reasoning, and to write and say more precisely what they intend. Such an education is essential to freedom, for without knowing how to tell the truth one is easily boxed in by sophistries. … Nothing is more abhorrent to Plato than the Sophists who use their art of persuasion to empower themselves through deliberately deceptive arguments with no concern for truth or other ultimate ends such as goodness and beauty.
