This paper explains the view point of Immanuel Kant's Categorical Imperatives. In his principal book entitled, "The Foundations of the Metaphysics of Morals," Kant explains why only the categorical imperative is the valid standard of moral obligation. He limits his discussion to specific willful actions in moral situations or conditions, where the will is (or should be) influenced only by reason or rational considerations, rather than by subjective or emotional considerations, such as laziness, convenience, or advantage (Kant). He writes that morality involves what actions are necessary and that concept comes only from reason or rational considerations. These rational considerations must, in turn, be a "single principle of obligation (Internet Encyclopedia)." It must also be stated as a command and has no reference to, or weighed against, the consequences of the action.
