The importance of learning in enabling the individual to put his potentials to optimal use is self-evident. Without education, the training of the human minds is incomplete. No individual is a human being in the working world until he has been educated in the proper sense.
Now I'm not saying you're not a human being without education. The mind was made to be trained and without education, a person is incomplete in that sense. Education makes man a right thinker and a correct decision-maker.
It achieves this by bringing him knowledge from the external world, teaching him to reason, and acquainting him with past history, so that he may be a better judge of the present. Without education, man, as it were, is shut up in a windowless room.

With education, he finds himself in a room with all its windows open to the outside world. In other words, people who are not educated have less opportunity to do what they want to do.
