1. Children under the age of seven (7) years.
2. Children over the age of seven (7) years, but under the age of fourteen (14) years, in the absence of proof that at the time of committing the act or neglect charged against them, they knew its wrongfulness.
3. Lunatics, insane persons, and all persons of unsound mind, including persons temporarily or partially deprived of reason, upon proof that at the time of committing the act charged against them they were involuntarily incapable of knowing its wrongfulness.
4. Persons who committed the act, or made the omission charged, under an ignorance or mistake of fact which disproves any criminal intent. But ignorance of the law does not excuse from punishment for its violation.
