Related: Causation, Intervening Cause
Specific Intent

A mental state requiring the defendant to intend a specific result or to do a further act, such as burglary (intent to commit a felony inside). It allows for voluntary intoxication defenses.

Related: General Intent, Mens Rea, Voluntary Intoxication
General Intent

A mental state where the defendant intends only the act, not a specific result or further consequence, such as battery. Voluntary intoxication is generally not a defense.
