A person is negligent with respect to circumstances when, because of a substantial lapse from due care, he fails to perceive or avoid a risk that such circumstances may exist.

When recklessness suffices to establish an element of an offense, then knowledge or purpose is also sufficient culpability for such element. When knowledge suffices to establish an element of an offense, then purpose is also sufficient culpability for such element.
