... Our individual well-being is intimately connected both with that of all others and with the environment within which we live.... Our every action, our every deed, word, and thought, no matter how slight or inconsequential it may seem, has an implication not only for ourselves, but for all others, too.
Experience is the only teacher we have. We may talk and reason all our lives, but we shall not understand a word of truth until we experience it ourselves.
