Thinking leads man to knowledge. He may see and hear, and read and learn, as much as he please; he will never know any of it, except that which he has thought over, that which by thinking he has made the property of his mind. Is it then saying too much if I say, that man by thinking only becomes truly man? Take away thought from man's life, and what remains?
Johann Heinrich PestalozziOur home joys are the most delightful earth affords, and the joy of parents in their children is the most holy joy of humanity.
