📖 Biblical Definition
God placed the Tree of the Knowledge of Good and Evil in the garden and commanded Adam not to eat of it, "for in the day that thou eatest thereof thou shalt surely die" (Genesis 2:17). The serpent's temptation was precisely this: "ye shall be as gods, knowing good and evil" (Genesis 3:5). The fall was not merely disobedience — it was the assertion of human moral autonomy. Adam and Eve chose to define good and evil for themselves rather than receive the definition from God. This is the root sin of all human history: the creature usurping the Creator's authority to determine what is right and what is wrong. Every subsequent sin flows from this original rebellion — man as his own god, his own lawgiver, his own judge.
📜 Webster 1828 Definition
KNOWLEDGE: A clear and certain perception of truth; learning; information.

KNOWLEDGE, n. [From know.] 1. A clear and certain perception of that which exists, or of truth and fact. 2. Learning; illumination of mind. 3. Skill; acquaintance with any fact or person. Webster understood knowledge as perception of truth — but the knowledge of good and evil in Genesis is something more dangerous: experiential knowledge of rebellion against God, not mere intellectual understanding.
📖 Key Scripture
• Genesis 2:16-17 — "Of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die."
• Genesis 3:5 — "For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil."
• Genesis 3:22 — "And the LORD God said, Behold, the man is become as one of us, to know good and evil."
• Isaiah 5:20 — "Woe unto them that call evil good, and good evil."
⚠️ Modern Corruption
The original sin of moral autonomy is now celebrated as the highest human virtue.

Modern culture has embraced the serpent's offer as liberation. "You shall be as gods, knowing good and evil" is now called "self-determination," "authenticity," and "living your truth." The entire framework of moral relativism — "who are you to say what is right or wrong?" — is a restatement of the Edenic temptation. Secular humanism and postmodernism both rest on the premise that humanity determines its own moral categories, which is precisely the sin that caused the fall. The biblical response is clear: God alone determines good and evil, and human flourishing depends on receiving His definitions rather than inventing our own.
Usage
• "The fall was not about fruit — it was about who gets to define good and evil. Adam chose himself. Every sin since has been the same choice."
• "When culture says 'you define your own truth,' it is repeating the serpent's original promise — and the result is the same: death."
