How does Aristotle present the human being? In this article I will interpret the way in which Aristotle understands the human being. In the first part of this article I will explain the concept of human telos. In the second part I will present how Aristotle defines the knowledge of the four causes in his theory. In the third part I will complete the idea of ​​the human being according to Aristotle. In the fourth part I will explain the four causes in Aristotle's theory. Finally, I will describe two types of virtues presented in the theory. In Aristotle's theory the notion of human telos can be translated differently as end, objective or purpose. According to Aristotle, we as human beings have a telos that our goal is to realize. This telos is based on our unusually human capacity for rational thought. From Aristotle's perspective, humans having a telos based on rationality leads to the conclusion that contemplation is the highest human good. Aristotle proposes a method by which it is possible to determine the human telos, namely by satisfying three specific criteria. Whatever the human telos is, it must be; reachable, in the sense that it can be reached by human action. Aristotle did not understand human action as a simple action performed because you are human, but noted that a human action is unique and distinctive only to human beings, which refers to thought. Secondly, it must be self-sufficient, which basically means that when it is isolated it lacks nothing else. Aristotle distinguishes that the telos is that which must be self-sufficient rather than the human being itself. This is because human beings always have external needs. A human being cannot fail to have the ability to isolate himself and not miss anything else. Thirdly it must… be in the middle of the paper… be. The final cause explains the end or purpose it serves. Natural objects are different from artificial objects in that they have an internal source of change. All causes of change in artificial objects lie outside the objects themselves, but natural objects can cause from the inside. Furthermore, Aristotle emulates that the natural world consists of reality. Aristotle refers to the natural world as a cosmos, that is, an ordered universe. Where there is order there is intelligibility. There are laws of nature and the most constitutional law of nature should be the law of causality, which is the fundamental law of the universe, where nothing abandons cause and effect. In the explanations that Aristotle gives from his text he makes no distinction between what something is and why something is. Every action performed occurs for a particular reason, which therefore makes the universe a purpose.
