Does achieving a degree means that you have become a civilized and educated human being? I don't think so. Getting knowledge won't make you an educated person. The most common example of illiteracy by educated people is when there is littering iin educational institutes and illiterate people are hired to clean the mess. cramming your course books won't bring wisdom, it will only bring knowledge without enlightenment.
This is true, getting a degrre doesn't make you literate or smart. I know a lot of big headed people who are degree holders who are stupid literally in real life. Diploma doesn't certify that a person is smart. There are lots of people who are not degree holders yet are genuises.
