The term "human nature" is vague and very broad, giving many philosophers the opportunity to try to make sense of it. Throughout history, theories have ranged from complete free will as a gift from God to no human nature at all. Two particular theories I would like to analyze are Sigmund Freud's psychological view and Aristotle's ethical view. Although Freud and Aristotle both believe that the mind plays a key role in human nature, they differ in that one believes that there is no such thing as complete rationality while the other believes that rationality is our natural function. Sigmund Freud, one of the most famous psychologists. till date he was known as the “Father of Psychoanalysis”. The main focus of psychoanalysis was the human personality hidden in the unconscious. The most famous analogy is that of the “tip of the iceberg”. Freud believed that the human mind was like an iceberg because the visible part of the iceberg represented the conscious mind while the unknown part of the iceberg represented the unconscious mind that causes us to act the way we do. According to Freud, the human mind was like an iceberg. personality depended on the conscious mind, the preconscious mind, and the unconscious mind, as well as the three components of personality: the id, the ego, and the superego. The id is considered to hold basic human instincts and is present from birth. It belongs to the unconscious and works through pleasure. Freud believed that most instincts came from two innate sources: "Eros" (the life instinct) and "Thanatos" (the death instinct). “Eros” includes the need to love, to be creative and sexuality (libido). "Thanatos" is the urge to use ...... middle of paper ......ts. In animals, they grow and reproduce, and you can tell whether an animal is happy or sad based on body language. As an objection to these claims, it can be said that a flaw in Aristotle's theory is that, although he believes that everything is done with good reasoning, it cannot be said that all events are good . Obviously, rationality disappears if someone is under the influence of alcohol or drugs. So if, while drunk, a person commits something morally wrong, such as raping a woman, how can we justify that it was a good thing? Furthermore, (Counterargument) Overall, I feel that Freud's theory of the unconscious is the superior view of human nature. I say this because although many critics have asserted the theory's validity, that doesn't change the fact that it was a breakthrough that paved the way for future psychological work..
