“ A man who belongs to some communist or revolutionary society wills certain concrete ends, which imply the will to freedom, but that freedom is willed in community. We will freedom for freedom’s sake, in and through particular circumstances. And in thus willing freedom, we discover that it depends entirely upon the freedom of others and that the freedom of others depends upon our own. ”
