For my part, I should be inclined to suggest that the chief object of education should be to restore simplicity. If you like to put it so, the chief object of education is not to learn things; nay, the chief object of education is to unlearn things.
Being incomprehensible offers unparalleled protection against having nothing to say...but writing with simplicity requires courage, for there is a danger that one will be overlooked, dismissed as simpleminded by those with a tenacious belief that the impassable prose is a hallmark of intelligence.
If one's life is simple, contentment has to come. Simplicity is extremely important for happiness. Having few desires, feeling satisfied with what you have, is very vital: satisfaction with just enough food, clothing, and shelter to protect yourself from the elements.
