"Who will teach the young wisdom and discipline? "
Wisdom is not taught, systems are taught. Wisdom comes from experiencing life, or it never comes at all. And life is its own discipline.
"What produces growth and progress? "
Perhaps if we are not pushed and prodded or made to feel ashamed, we will achieve our growth — and our joy as well.
Some day, after we have mastered the winds, the waves, the tides, and gravity, we shall harness the energies of love. Then, for a second time in the history of the world, we will have discovered fire.
