Aristotle says that every action that a human does, they consider the end to be good. There are higher ends and subordinate ends. The higher ends are ends in themselves and the subordinate ends are the means to higher ends. He also says that good is a part of political science as in politics, people are concerned with what is the best end for a human but then what is best for one person may not be best for another. Thus, we can only have a rough outline of good.

Everyone agrees that the supreme good is happiness but people argue on what happiness consists of. Some people think that sensual pleasures are the greatest god while on the other hand, some people think that honor is the greatest good. Plato suggests that there is only one form of good and that all good things are good in the same way. Happiness is the highest good because it is an end in itself.

We see people as ‘good’ only if they perform their function well. The thing that separates us from animals and plants is our rationality. Thus, good should be an activity of the rational soul.

When e are talking about the life of a person, we consider the life as a whole and not just a few moments of it. Through this, we could say that a person can only be considered happy only after he dies when we can examine their lives as a whole. Aristotle also says that the way his descendants behave may affect the happiness of that person.

We can divide the soul into 2 parts- a rational part and an irrational part. The irrational part can then be divided in a vegetative part, which helps with our growth and nutrition and an appetitive part, which governs our impulses. The rational part of the soul controls those impulses and thus a person with greater rationality is better able to control their impulses.
