The necessary consequence of man's right to life is his right to self-defense. In a civilized society, force may be used only in retaliation and only against those who initiate its use. All the reasons which make the initiation of physical force an evil, make the retaliatory use of physical force a moral imperative. If some "pacifist" society renounced the retaliatory use of force, it would be left helplessly at the mercy of the first thug who decided to be immoral. Such a society would achieve the opposite of its intention: instead of abolishing evil, it would encourage and reward it.
Ayn RandI am opposed to all forms of control; I am for an absolute laissez faire, free, unregulated economy. I am for the separation of the state and economics, just as we had separation of state and church, which led to peaceful coexistence among different religions...so the same applies to economics. If you separate the government from economics, if you do not regulate production and trade, you will have peaceful cooperation, and harmony and justice among men.
