“Freedom is not simple, for it always is involved with responsibility. The relation between freedom and responsibility is not a “balance” to be expediently adjusted by governments or citizens, who without both can have neither. I have quoted John Milton’s definition of freedom before, and I am going to quote it again, for it is complex and precise enough to have the force of an essential justice: “To be free,” Milton wrote, “is precisely the same thing as to be pious, wise, just, and temperate, careful of one’s own, abstinate from what is another’s and thence, in fine, magnanimous and brave.”
