" If we know an object has symmetry, we can deduce some of its properties. If we know a set of objects has symmetry, we can infer from our knowledge of one object the existence and properties of others. And if we know that the laws of the world have symmetry, we can infer from one object the existence, properties, and behavior of new objects. "

― Frank Wilczek , The Lightness of Being: Mass, Ether, and the Unification of Forces
