Immanuel Kant was generally regarded as the last major philosopher of the early modern period and one of history's most influential thinkers. His ethical theories were presented in two works. The Foundations of the Metaphysics of Morals (1785) was Kant's "search for and establishment of the supreme principle of morality." In The Critique of Practical Reason (1787) Kant attempted to unify his account of practical reason with his work in theCritique of Pure Reason. Kant was the major proponent in history of what is called deontological ethics. Deontology is the study of duty. On Kant's view, the sole feature that gives an action moral worth is not the outcome that is achieved by the action, but the motive that is behind the action. The Categorical Imperative was the name of Kant’s moral law and the famous statement of this duty: "Act only according to that maxim by which you can at the same time will that it should become a universal law." (McCormick, 2006). Kant’s notion on moral judgment i.e. the ability to personally determine the motive behind and outcome of one’s action, made freedom play a significant role in much of his ethical theories. According to Kant what makes human beings different from inanimate things and other lower level living beings is that people have dignity based on their ability to choose freely what they will do with their lives, and they have a fundamental moral right to respect other people’s choices as well. It is a violation of human dignity to manipulate people or use them in ways against their will and choice. There are four different aspects of the basic right which are to be taken into consideration as people choose: the right to told the truth and to be informed about matters that significantly affect choices; right of privacy or the freedom to do, believe, and say whatever a person chooses in his/her personal life so
