To educate a person in mind and not in morals is to educate a menace to society. Theodore Roosevelt
What this quote means is that educating a person with knowledge without also teaching morality creates a person who will cause problems for society. An educated person without morals can do more harm to society than an uneducated person with or without morals. When a school teaches a person how to run a business, it must also teach that person what constitutes ethical and moral behavior, and that acting in a moral fashion must be considered when making business decisions.
