No concept man forms is valid unless he integrates it without contradiction into the sum of his knowledge.
Ayn RandDictatorship nations are outlaws. Any free nation had the right to invade Nazi Germany and, today, has the right to invade Soviet Russia, Cuba, or any other slave pen. Whether a free nation chooses to do so or not is a matter of its own self-interest, not of respect for the nonexistent 'rights' of gang rulers. It is not a free nation's duty to liberate other nations at the price of self-sacrifice, but a free nation has the right to do it, when and if it so chooses.
Ayn RandMan cannot survive except through his mind. He comes on earth unarmed. His brain is his only weapon. Animals obtain food by force. man had no claws, no fangs, no horns, no great strength of muscle. He must plant his food or hunt it. To plant, he needs a process of thought. To hunt, he needs weapons,and to make weapons - a process of thought. From this simplest necessity to the highest religious abstraction, from the wheel to the skyscraper, everything we are and we have comes from a single attribute of man -the function of his reasoning mind.
