What is the goal of all education? The profound answer, which great cultures have touched on again and again, is this: the true goal of education is similar to the goal of human life. Whatever skill you are learning, from early childhood, should have the ultimate purpose of making you more free, virtuous and happy; these are at the heart of human life. All the practical skills we learn do this to a certain extent; by learning to speak, to cook, or to build a house, we are becoming freer. However, as the ancient Greeks saw, liberty of soul is far more important than liberty of body.
A king who rules the world, but is enslaved to error or vice, is truly not as free as a wise and good man whose body is in chains. As long as a person is enslaved to error or vice he cannot be truly called free, virtuous or happy, no matter how much wealth, influence or power he has. It is only knowledge of the truth and obedience to it which sets you free. That is why the goal of true education can never be economic prosperity or mere leadership ability - or empty curiosity. The goal must be to know the Truth.
Knowing the Truth is not just a matter of collecting information that happens to be factual. Information such as this falls out of the brain just as easily as it falls into it; it usually isn’t truly understood. The most important truths can’t be known unless the mind is prepared to grasp them. What is required for this type of education is intellectual training.
