This assignment provides a comprehensive analysis of Immanuel Kant's theory on morality, which is based on the idea that wrong and right actions are not dependent on their consequences but on whether they fill their duties. The report compares Kant's theory with utilitarianism, which focuses on maximizing overall happiness or well-being. It examines why Kant's theory is more preferable than other philosophers such as William David Ross, Henry Sidgwick, and John Stuart Mill.
