(720 ILCS 5/4-3)
(from Ch. 38, par. 4-3)
(a) A person is not guilty of an offense, other than an offense which
involves absolute liability, unless, with respect to each element described
by the statute defining the offense, he acts while having one of the mental
states described in Sections 4-4 through 4-7.
(b) If the statute defining an offense prescribed a particular mental
state with respect to the offense as a whole, without distinguishing among
the elements thereof, the prescribed mental state applies to each such
element. If the statute does not prescribe a particular mental state
applicable to an element of an offense (other than an offense which
involves absolute liability), any mental state defined in Sections 4-4,
4-5 or 4-6 is applicable.
(c) Knowledge that certain conduct constitutes an offense, or knowledge
of the existence, meaning, or application of the statute defining an
offense, is not an element of the offense unless the statute clearly
defines it as such.
