According to Osho, innocence is the mature flowering of consciousness - a lucid, rebellious not-knowing that has dropped borrowed beliefs and honestly sees, "I know nothing," like Bodhidharma or Socrates. Stupidity is unconscious conditioning: secondhand certainties that never look inward, cling to labels, and serve vested interests. A child is ignorant, not innocent; innocence is awakened ignorance, while stupidity is blind belief and outward judgment.
Innocence means being awake and honest that you don’t know, while stupidity means being asleep in borrowed beliefs and never looking inside.
