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 RandEver since Kant divorced reason from reality, his intellectual descendants have been diligently widening the breach.
Ayn RandI am not the means to any end others may wish to accomplish. I am not a tool for their use. I am not a servant of their needs. I am not a bandage for their wounds, I am not a sacrifice on their altars.
Ayn RandI stand here on the summit of the mountain. I lift my head and I spread my arms. This, my body and spirit, this is the end of the quest. I wished to know the meaning of all things. I am the meaning. I wished to find a warrant for being. I need no warrant for being, and no word of sanction upon my being. I am the warrant and the sanction. Neither am I the means to any end others may wish to accomplish. I am not a tool for their use. I am not a servant of their needs. I am not a sacrifice on their alters.
