In other words Virtue ethics focuses upon what kind of human being you ought to be rather than the actions of a human being. Plato, in his book Republic, focused on justices and further on argues that, with his beliefs about the soul, that there is a virtue connected to such part of the soul. These different parts of the soul, are called imperative and it is divided into three parts, with a virtue connected to it. These virtues are the cardinal virtues; thus reason and wisdom are one, the human spirit performing well is paired with courage and destiny which is paired with temperance or otherwise known as moderation (self-control). If we have all these virtues we can obtain justice, the fourth virtue. According to Plato, justice is an important virtue because it balances out the interrelationship between the parts of the soul. There is justice when reason rules over spirit and desires. Wisdom is the knowledge of Forms especially the knowledge of the Form of God, having to know what goodness is itself.
The forms are the fixed, unities and unchanging concepts that are ultimately real. This type of thinking presupposes both anthropological dualism and ontological dualism. The problems with Plato is that he has based his argument on a questionable metaphysic cleansing that we cannot prove something we have little to no experience to. The concept about the soul and the priparte are criticised because there is no empirical evidence to support it, it is only logic and reason. A fortiori is the criticism of the preparative soul because there is no solid empirical evidence to support it. Furthermore there is no evidence to support the claim that there are forms, again it is only a concept based on reasoning.
Lace Wing presents the argument that even if ontology accepted Virtue Ethics, then it is unclear what the practical implications are. If Virtue Ethics is an anti-ethical theory then to how would you practice it? What would you do afterwards? How would knowing these virtues and forms affect you? In the hope of rescuing Virtue Ethics, Aristotle (Platos student) delivers his interpretation of this ethical theory. Aristotle does not necessarily agree into Platos metaphysic, epistemology or ontology but he does agree with Plato that reason is vital to virtues. This is because humans are rational animals and agrees that virtues are vital to human flourishing otherwise known as eudsimonia. Unlike Plato, Aristotle believes that there are only two kinds of virtues; intellectual virtues and moral virtues.
