Utilitarianism argues that we ought to do something or take an action because it will give more happiness than there will be in the case of doing anything else. Utilitarianism is a moral theory holding that the moral action is the one that will (probably) maximize utility, which maximizes well-being, happiness and welfare and minimizes suffering.
Kantian ethics is based on the idea of moral duty proposed by a German philosopher Immanuel Kant. It suggests that we should only act on the principles that we can and an action is only good if performed out of duty. The issue here is likely to be that when an individual acts immorally, he/she wants everyone else to obey â€˜the rules’, everyone but him. We can also define the Categorical Imperative as the Principle of Humanity. It says that whenever we act, we must always treat everyone as â€˜ends’ and not as â€˜mere means’ - thus motivation behind each action will be of good nature.
It is a theory that suggests that an action that is morally good is determined by God’s commands. Both monotheistic religion and polytheistic religion followers in ancient and modern times have always accepted the importance and effectiveness of God’s commands in ensuring morality.
Virtue ethics emphasizes the role of a person’s character and the moral character for evaluating or determining ethical behaviour. It emphasizes the virtues, in contrast to the approach that emphasizes rules or duties (deontology) or the one that emphasizes the consequences of actions (consequentialism).
In conclusion I have to say that the systems that have the most appeal to me are: Devine Command and Utilitarianism. The reason for my choice is that Devine Command depends on faith thus it will give me strength and hope. However, Utilitarianism will keep me going to ensure that I get better and respect my right to life hence becoming happier.
