kant tells us that we should act only according to those maxims that could be universally accepted and acted on.consider how kant might respond to the egoist view that all human behavior is intended for one's own self interest.For example Kant believed that truth telling could buy lying could not be made a universal law if everyone lied whenever it suited them rational communication would be impossible thus lying is unethical.This condition of universality not unlike the Golden rule prohibits us from giving our won personal point of view priyileged status over the points of vieew of others.it is a strong requirement of impatiality and equality for ethics
