     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.

     In some modern countries it has for some time been fashionable to think that by free education for all-one

can solve all the problems of society and build a perfect nation. But we can already see that free education for

all is not enough; we find in such countries a far larger number of people with university degree; they refuse

to do what they think “low” work; and, in fact, work with 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 that of a professor; we can live without education, but we die if we have no food.

If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our

towns.

     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 work suited to his brains and ability and, secondly, that

we can realize that all jobs are necessary to society, and that is very bad to be ashamed of one's work. Only

such a type of education can be considered valuable to society.
