"Few formulas in philosophy have been so widely accepted and variously interpreted as Kant's injunction to treat humanity as an end in itself"(Hill, 38). Immanuel Kant's views, as elucidated in his book, Groundwork of the Metaphysics of Morals, are based on the belief that "people count" by prohibiting actions which exploit other individuals in order for self-prosperity or altruistic ends. Ethics then, are confirmed by the dignity and worth of the rational agency of each person. Since human beings are the only rational beings capable of decision making and reasonable judgement, humanity must be valued. Kant proposes a test that ensures that humanity is treated with respect, and not used merely as an instrument. To understand how he defines this test, we must first take a look at the foundation of his main principle, the Categorical Imperative.
Kant's way of determining morality of actions is quite different from other philosophers, and many find it extremely hard to grasp or implausible. The central concept of his basic test for morality found in his Groundwork of the Metaphysics of Morals is the categorical imperative. "The representation of an objective principle, insofar as it is necessitating for a will, is called a command (of reason), and the formula of the command is called an imperative"(Kant, 24). In other words, an imperative is something that a will ought or shall do because the will is obligated to act in a way in which conforms to moral law. Imperatives can also be referred to as the supreme principle of morality.
According to Kant, there are two types of imperatives: hypothetical and categorical. Hypothetical imperatives are actions that look for the best means to a goal, however, the goal might not necessarily be an end in itself. On the other hand, the categorical imperative is an objectively necessary means to an end in itself, and the action to obtain the end, must have moral worth. If we as rational
