"For only when family upbringing and school education have inculcated in the individual a knowledge of the cultural and economic and, above all, the political greatness of his own country — then, and then only, will it be possible for him to feel proud of being a citizen of such a country. I can fight only for something that I love. I can love only what I respect. And in order to respect a thing I must at least have some knowledge of it."
