Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them our purpose is to fit them for life. As soon as we realize this fact, we will understand that it is very important to choose a system of education which will really prepare children for life.

Because of their degrees, they refuse to do what they think 'low' work and, in fact, work with the hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than the work of a professor—we can live without education, but we will die if we have no food. In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability and, secondly, that we can realize that all jobs are necessary to society, and that it is very bad to be ashamed of one's work, or to scorn someone else's.
