Innocence

Bouguereau's L'Innocence: Women, young children, and lambs are all symbols of innocence.
Innocence by Pierre Paul Prud'hon, c. 1810

Innocence is a lack of guilt, with respect to any kind of crime, or wrongdoing. In a legal context, innocence is the lack of legal guilt of an individual, with respect to a crime. In other contexts, it is a lack of experience.
