"Immaturity is the incapacity to use one's intelligence without the guidance of another"

This quote by philosopher Immanuel Kant recommends that immaturity is the failure to use one's intelligence and make choices separately, without relying on the assistance or direction of somebody else. Basically, he is stating that a mature and intelligent person has the ability to think and act on their own, while an immature individual lacks this ability and requires assistance or support from others.
