The time is passed when you could have a happy minority living upon the misery of the great mass. That time is passed. People won’t acquiesce in it, and you will have to learn to put up with the knowledge that your neighbor is also happy, if you want to be happy yourself. I think, if people are wisely educated, they will have a more expansive nature and will find no difficulty in allowing the happiness of others as a necessary condition of their own.
