Simply defined, happiness is the state of being happy. But what exactly does “being happy” mean? Repeatedly, many philosophers and ideologues have proposed ideas about what happiness means and how to achieve it. In this article I will argue that Aristotle's conception of happiness is more ethically driven than John Stuart Mill's. First, in examining Mill's version of unprincipled happiness, I will criticize the imperfections of his definition in relation to ethics. Next, I intend to identify Aristotle's core values ​​for happiness. According to Aristotle, happiness derives from virtue, while Mill believes that happiness derives from pleasure and the absence of pain. Ethics are the moral principles that govern a person's behavior that are guided by virtues – good character traits. Therefore, Aristotle focuses on three things, which I will outline to answer the question, “what does it mean to live a good life?” The first of which is the number one good in life is happiness. Secondly, there is a difference between moral virtues and intellectual virtues, and finally, leading a good life is a state of character. Personally and widely accepted, happiness is believed to be a true determining factor in leading a well-intentioned, rational and satisfying life. However, it is important to note the ways in which one achieves one's happiness, through people and experiences to reach that state of being. As a result, Aristotle's focus on happiness presents a more questionable notion of "good character" and "rationality." John Stuart Mill believes in a utilitarian society in which people are seen as "things". Furthermore, in utilitarianism the focus of the objective is “far-sighted”, looking at the consequences but not at the ini...... middle of paper ......g the other consequences and harms of the decision made In conclusion , Aristotle's elucidation of happiness is based on ethical grounds because for him happiness is desired only for happiness's sake. The life of fame and fortune is not the life for Aristotle. Happiness is synonymous with living well. Living well is living with virtue. Virtue presents humans with identification for morality, and, for Aristotle, we choose to have “right” morality. Aristotle defines humans by nature as dishonored when they make a bad decision. Therefore, if you choose to act on pleasure, as John Stuart Mill states, for happiness, you may be choosing the wrong means to do so. Happiness is a choice made rationally among many choices to achieve this state of mind. Happiness should not be a way to “win” in the end, but a way to develop a well-mannered and principled reputation.
