It is a truism that education is no longer a luxury. Education in this day and age is a necessity.
Books are infinite in number and time is short. The secret of knowledge is to take what is essential. Take that and try to live up to it.
Education is an organic necessity of a human being.
A good teacher does not get lost in the details, but points to what is essential so that the child or student can find meaning and joy in life.
Education is what is left after all that has been learnt is forgotten.
For a very small expence the public can facilitate, can encourage, and can even impose upon almost the whole body of the people, the necessity of acquiring those most essential parts of education.
I don't think that the basics that kids need have changed in 10,000 years.
