"Nations do not now stand in the same relation to each other that they did ages ago. No nation can now shut itself up from the surrounding world, and trot round in the same old path of its fathers without interference. The time was when such could be done. Long established customs of hurtful character could formerly fence themselves in, and do their evil work with social impunity. Knowledge was then confined and enjoyed by the privileged few, and the multitude walked on in mental darkness."
