I believe that my theory is correct; for whatever be the question upon which I am arguing, whether it be religious, philosophical, political, or economical; whether it affects well-being, morality, equality, right, justice, progress, responsibility, property, labor, exchange, capital, wages, taxes, population, credit, or Government; at whatever point of the scientific horizon I start from, I invariably come to the same thing—the solution of the social problem is in liberty.
