In Aristotle's writings, seen in Nicomachean Ethics, it is evident that Aristotle believes that friendship is necessary for a virtuous and therefore happy life. I believe this is accurate because of the similar conditions needed for a complete friendship and happy life. It is also evident that friendship is useful in achieving a happy life because friendship can facilitate the performance of virtuous actions. Its interpretation can be misunderstood and mistakes can be made in practice, so we will have to discuss these follies too, to understand all the effects of friendship on achieving a happy life. Let us first examine the similarities of friendship with that of happiness and virtue, which we discussed earlier, are the most necessary part of a happy life. Aristotle describes happiness by saying that “happiness is the most choice worthy of all goods (1097b17-18).” His idea of ​​choiceworthy is something we choose “for its own sake, never for something else (1097b).” Friendship is seen as similar to happiness when Aristotle describes friendship as "worthy of choice in itself (1159a27)". Demonstrated above, virtue is necessary for a happy life because "happiness is a certain kind of activity of the soul in accordance with virtue (1099b26-27)." Since virtue is an integral part of happiness, the similarity between friendship and virtue is relevant to the relationship between friendship and happy life. Aristotle describes virtues as “states (1106a14)” and at the same time also describes friendship as “a state (1157b30)”. He goes on to say: “As, in the case of virtues, some people are called good in their state of character, others good in their activity, the same I… middle of paper…. ..very difficult (1158a14-16).” In conclusion, the similarities between friendship and virtue allow the two states to correspond to each other in a happy life. The purpose of friendship is not only to coexist with virtue but also, through the actions of friends, virtue and friendship strengthen each other, making happiness even easier to achieve thanks to it. Aristotle sums it up well, saying that “the friendship of good people is good, and increases the more often they meet. And they seem to get even better thanks to their activities and mutual correction. For each molds the other in what he approves, so that you will learn what is noble from noble people (1172a11-14).”Bibliography: Works CitedAristotle. The Nicomachean ethic. David Ross, trans. J. L.
