“Experience is the child of Thought, and Thought is the child of Action. We can not learn men from books.”

“There is frequently more to be learned from the unexpected questions of a child than the discourses of men.”

“… besides love, independence of thought is the greatest gift an adult can give a child.”

“We must speak up for the children of Pakistan, India and Afghanistan who are suffering from terrorism, poverty, child labour and child trafficking. Let us help them through our voice, action and charity. Let us help them to read books and go to school. And let us not forget that even one book, one pen, one child and one teacher can change the world.”

“There is no mode of action, no form of emotion, that we do not share with the lower animals. It is only by language that we rise above them, or above each other—by language, which is the parent, and not the child, of thought.”

“If you feel proud, let it be in the thought that you are the servant of God, the son of God. Great men have the nature of a child. They are always a child before Him; so they are free from pride. All their strength is of God and not their own. It belongs to Him and comes from Him.”

“We learn from experience that men never learn anything from experience.”

“I'd far rather leave a thought behind me than a child. Other people can have children.”

“When I was a child, I thought as a child. But now I have put away childish things. … I must be scientific.”

“Learning is not child's play; we cannot learn without pain.”
