Kant believed that what created the problem of ethical behavior is the duality of human nature. Since humans are both sensible and intellectual, and at the same time motivated by impulse, they must be guided by rules of conduct to balance the two. He believed that everyone could decide right and wrong based on the will behind the action, rather than the action itself. In deciding whether one's actions were moral, he said it should be considered what the universal benefit would be if everyone behaved in such a fashion. For example, if everyone stole, the result would be chaos and violence. Therefore, a moral person would consider it unethical to steal. In abiding by these laws, it is possible to see how a universal code of ethics could be built up.
