Through a readjustment of economic conditions that allows those who are poor or middle class to have their fair share of possessions, fulfillment and meaning could be achieved. Marx is concerned with economic conditions in considering the meaning of life and believes that the meaning of life can only be analyzed in materialistic terms. Therefore, Marx argues that people are defined by what they do or produce. In a capitalist system people are ultimately unhappy because they are unable to do what satisfies them. Marx argues that if capitalism were overthrown it would lead to greater human happiness. In Marx's famous quote, “work is the source of happiness”, he presents the importance of material life. Marx's view of happiness illustrates that it is the combination of creation and enjoyment. These philosophers offer a comprehensive perspective on achieving happiness. In examining these philosophers, I believe that Marx is too focused on the materialistic aspects, and it is possible to be happy and have nothing. It is equally possible to be rich and unhappy. On the other hand, with the philosopher Kant, I do not believe that reason is the only driving factor in achieving happiness. My views seem to align more with Aquinas and Plato. I agree that others can have different types of happiness depending on what they value, like Plato
