"Yes, I believe in Freedom -- equal freedom. I want no freedom for myself that all others may not equally enjoy. Freedom that is not equal is not freedom. It is, or may easily become, invasion, and invasion is the denial or the death of freedom. The Spencerian formula -- 'Each has the right to do as he pleases so long as he does not invade the equal right of others,' tells what freedom means. It is equivalent to saying that liberty, wedded to responsibility for one's acts, is the true and only basis of good conduct, or of morality."
