Ancient Hebrew nation strongly advocated wisdom. The first prerequisite of wisdom is to have the ability to distinguish between good and evil, which was first recorded in the myth of the Garden of Eden in the Bible. The fruit that enables Adam and Eve to distinguish between good and evil is the fruit of wisdom, which is the fruit of knowledge, or the fruit of civilization. The fruit of wisdom is also called the forbidden fruit, which represents the incest taboo and reflects instinctive fears of early humans for incestuous marriage relationship. Adam and Eve completed the process of ethical choice and self-awareness resulting from their behavior of eating the forbidden fruit. The snake in the Garden of Eden had the duality of good and evil, and reflected the dialectical relationship between good and evil. God's curse, the loss of Paradise, and out of the garden of Eden involved some basic ethical issues, such as crime and punishment, forgiveness and mercy, atonement and salvation. Love is the highest moral goals.
