Boys [should be] inured from childhood to trifling risks and slight dangers of every possible description, such as tumbling into ponds and off of trees, etc., in order to strengthen their nervous system... They ought to practice leaping off heights into deep water. They ought never to hesitate to cross a stream over a narrow unsafe plank for fear of a ducking. They ought never to decline to climb up a tree, to pull fruit merely because there is a possibility of their falling off and breaking their necks. I firmly believe that boys were intended to encounter all kinds of risks, in order to prepare them to meet and grapple with risks and dangers incident to man’s career with cool, cautious self-possession...

People ask me how it happens that my children are all so promptly obedient and so happy. As if it chanced that some parents have such children or chanced that some have not! I am afraid it is only too true, as someone has remarked, that "this is the age of obedient parents!" What then will be the future of their children? How can they yield to God who have never been taught to yield to human authority? And how well fitted will they be to rule their own households who have never learned to rule themselves?
