Education without morality and morals without education are impossible. All humanitarian subjects (history, literature, art) speak with soul, heart, and not with mind. Literature teaches us to understand the human soul, feelings (love, friendship, moral principles, fidelity ...). The History tells about the mistakes and victories of mankind. And it teaches us how to avoid these mistakes. Art is generally a separate "language without words" ... The fact that educated people become scoundrels is not a fraud in education but result of mental or psychological pathology, conditions of upbringing and life, grievances and injuries.
It's impossible to speak with the soul or the heart without the mind. Like it or not, everything that comes through one of our 5 senses goes through out mind. Maybe these things could influence our metaphorical heart, but you can't just disregard the mind. I hate to disappoint you, but there is so much different literature out there. Believe it or not, not all literature teaches good things. There is satanic or terrorist extremist literature. Would they also teach "love, friendship, moral principles, fidelity"? There can be very different quality of education. It's not good to generalize.
