A Critique of Kant's Deontology

One of the questions raised in ethics is the assessment criteria of moral behavior. Immanuel Kant, a German philosopher, believes that the action has moral value only when it is consistent with one’s duty and the agent performs it as his duty and has no motive in doing it except perfuming his duty. Given this, we should refer to categorical imperative to know which action is consistent with duty. By categorical imperative, which specifies all our moral duties, it is meant that it requires an agent to act only in ways which could be willed as a universal law. He considers categorical imperative as the immediate judgment of practical reason, and just as this affair is categorical the judgments obtained from it is categorical, too. Some criticisms are leveled to Kant’s ethical school (doctrine). Using theoretical_analytical method, this research is intended to expound and comment on Kant’s ethical school.
