Kant brought about a revolution to bring a separate ethics, formal and go ontological. Kant has a dualistic conception of man, by nature simultaneously shows a willingness to animality while being material that has a body endowed with appetites, desire and needs of biological order, but also a willingness to humanity, its top and rational responsibility and consciousness, the sense of duty capable of moral action. Kant proposes a rational ethics, reason autonomy consisting of man have the strength to follow the dictates of reason, no social pressure or biological inclinations threaten to divert to a different direction. Respect for duty is a central notion in a Kantian ethics, showing us an example to characterize the moral action and distinguishes three types of action: action against the duty that is what happens when a trader exploits customers, charging excessively high prices, this action has no moral value. Another action is in accordance to duty, in the case of merchant does not sell expensive to retain customers or eventually get another, this action lacks moral value because it is just a means to an end, and finally the action by duty, which in the case of a trader who does not sell expensive because they know it is their duty, and are actions like this that according to Kant are the true moral action.
The creation of a universal ethic was in fact the aim of Kant, to overcome the ethical materials and grounded the experience without universal validity, thus formulated the categorical imperative that says to act on a maximum so that you can at the same time will that it should become a universal law and highlights the idea of man as an end and not as a means .
