Dreams, books, are each a world; and books, we know, Are a substantial world, both pure and good: Round these, with tendrils strong as flesh and blood, Our pastime and our happiness will grow.
The most venerable, clearly understood, enlightened, and reliable constant in the world is not only that we want to be happy, but that we want only to be so. Our very nature requires it of us.
When you have read the Bible, you will know it is the word of God, because you will have found it the key to your own heart, your own happiness and your own duty.
