A special tree is in a story. 
A special tree is in an old story. 

In the story of the Garden of Eden, there are two special trees. 

A snake told Eve to eat the fruit. She and Adam both ate it. Because they did not obey, they had to leave the garden. This is often called the original sin in Christian belief. Many people think the fruit was an apple. But the Bible does not say it was an apple. Some Jewish traditions say it might be a fig or wheat. In Islam, the tree is sometimes called the tree of immortality. Some people think the phrase "good and evil" means "everything."
Different groups have many ideas about this tree. Gnostic groups believed the tree was actually a good thing. They thought eating it helped people gain wisdom. In Jewish mysticism, people work to find holy sparks in the world. This helps fix the mistake made at the tree.
The tree of the knowledge of good and evil is a famous part of a story. It appears in the book of Genesis. This story describes the Garden of Eden. In the garden, God placed a man named Adam. 

The story describes how the rule was broken. A serpent spoke to Eve in the garden. The serpent persuaded her to eat the fruit. 
Different cultures have many ideas about what the tree was. Jewish sources suggest many things. It might have been a fig tree. Some say it was a grape vine or a stalk of wheat. Other traditions mention a nut tree or an etrog fruit. In the Shia Islamic tradition, some believe the fruit was wheat or barley. The Quran does not use the long name for the tree. It often calls it "the tree." 
Scholars also study the meaning of the phrase "knowledge of good and evil." In Hebrew, the words literally mean "good and evil." This might be a figure of speech called a merism. A merism uses two opposite words to mean everything. This is similar to how some ancient Egyptian phrases worked. Some thinkers believe the tree gave knowledge of everything. Others think it meant the wisdom to rule or punish. Scholar Nathan French suggests it meant the wisdom to use ultimate power. This makes the tree a very deep subject for study.
Many different belief systems look at this story in unique ways. Gnosticism is one example of a group with a different view. They believed the tree was actually sacred or positive. They thought eating the fruit was a way to find salvation. In Jewish mysticism, known as Kabbalah, the sin caused a big task. People try to find holy sparks trapped in the world. They do this to fix the mistake made at the tree. These ideas show how one story can mean many things to many people. 
The tree of the knowledge of good and evil is a central element in the Genesis narrative. It is one of two specific trees located in the Garden of Eden. The other tree mentioned in the text is the tree of life. This tree is significant because it represents a boundary between humans and the divine. While the tree of life appears in other contexts, the tree of knowledge is unique to the Genesis account. Some scholars have even debated whether these two trees are actually different names for the same thing.

The mechanism of the story involves a specific command and a subsequent act of disobedience. In Genesis 2, God places Adam in the garden and allows him to eat from any tree except the tree of knowledge. After this command, God forms Eve. In Genesis 3, a serpent approaches Eve and persuades her to eat the forbidden fruit. She then shares it with Adam. Because they broke the command, God expels them from the garden. This sequence of events is often viewed as the moment human nature changed.

Scholars have many different interpretations regarding the phrase "knowledge of good and evil." In Hebrew, the term is *Hada'at tov wa-ra*. This may be a merism, which is a literary device. A merism pairs two opposite terms to imply a much larger, general meaning. For example, "good and evil" might simply mean "everything." Some scholars suggest the tree provided omniscience, or the knowledge of everything. Others, like Nathan French, suggest it represents the wisdom required to administer reward and punishment. This implies the fruit granted the wisdom to wield ultimate power.
Jewish traditions offer various identities for what this tree might have been. Some sources suggest it was a fig tree, as Adam and Eve used fig leaves for clothing. Other traditions propose it was a grape vine, a stalk of wheat, or a nut tree. The Babylonian Talmud even mentions the etrog fruit or a grape vine. In the Kabbalah, which is Jewish mysticism, the sin of the tree had a profound effect. It was believed to have caused the divine presence, the Shechinah, to depart from the earth. The task of Kabbalah is to perform *tikkun olam* to rectify this sin. This involves sifting through the world to find and liberate holy sparks trapped in the mixture of good and evil.

Christianity views the eating of the fruit as the "original sin." This act is often called the "fall of man." Augustine of Hippo taught that the tree was both a real object and a symbol. He argued that the fruit itself was not evil because God's creation is good. Instead, the sin was the act of disobedience. This disobedience caused disorder in the creation. In Western Christian art, the fruit is almost always shown as an apple. This may come from a Latin pun where the word for apple sounds like the word for evil. However, the Bible does not explicitly state the fruit was an apple.
Islam provides a different perspective on the event. The Quran does not use the specific phrase "tree of the knowledge of good and evil." Instead, it refers to it as "the tree" or the "tree of immortality." In this tradition, Satan (Iblis) tells Adam and Eve that the tree will make them immortal or like angels. The Quran describes the event as a "slip" rather than a permanent state of sin. After eating, Adam and Eve repented to God and were forgiven. While Western tradition often identifies the fruit as an apple, Shia Islamic tradition considers it to be wheat or barley.

Other belief systems, such as Gnosticism, hold views that contrast sharply with mainstream traditions. Gnostics believed the tree was actually a positive or sacred object. They argued that the "archons," or rulers, were the ones who lied to Adam and Eve. In their view, eating the fruit was the path to salvation and the acquisition of *gnosis*, or true knowledge. This shows how the same ancient text can be interpreted to support entirely different moral frameworks. The tree remains a powerful symbol for exploring the relationship between humanity, morality, and the divine.
