If there is any principle of the Constitution that more imperatively calls for attachment than any other it is the principle of free thought―not free thought for those who agree with us but freedom for the thought that we hate. 如果宪法中存在一条相对来说更应引起我们关注的原则的话，那么，它就非思想自由原则莫属。――不是为与我们意见一致的人的思想自由，而是为那些我们所痛恨的思想的自由。
