"Ideas are cosmopolitan. They have the liberty of the world. You have no right to take sword and cross the bounds of other nations, and enforce on them laws and institutions they are unwilling to receive.
But there is no limit to the sphere of ideas. Your thoughts and feelings, the whole world lies open to them, and you have the right to send them into any latitude and to give them sweep around the earth to the mind of every human being." HenryWardBeecher
