Intelligence and education grant the possessor greater power than their peers; this ought create a responsibility. This responsibility demands them to think about the matters before them and lead those who lack their capacity. It is not enough for a person who has cruised through life on their natural talents to rely upon their personal aptitudes and cruise through life; a person with great talents ought use them.
That is not so say that all should be rewarded equally either; rather that those who can contribute great things to our society should do so. While we must not structure our society so that it takes from those with ability to reward mediocrity, we should always strive to make each member of our teams and of our community strive to do their very best. It not only makes the world a better place, but is infinitely more rewarding.
