Quote preview background for Ayn Rand
Man cannot survive except by gaining knowledge, and reason is his only means to gain it. Reason is the faculty that perceives, identifies and integrates the material provided by his senses. The task of his senses is to give him the evidence of existence, but the task of identifying it belongs to his reason, his senses tell him only that something is, but what it is must be learned by his mind.

Now putting against me a knife and saying "Go away... give me my daughter... give me her back"..., don't you see the people laugh at you, don't you see it. Look their faces, with so many smiles, but they aren't people, they are from the army, off, off for god sake they are soldiers which have guns. Have killed few people, have taken your daughter and they are many as a number than you and your whole family... Probably this part as an General I must skip it, because it's logical however look it and from this side, nobody will sacrifice so you to be happy... you will die.. O, o, the poor little girl crying in front of the people, she just saw her mother pointing with a knife against the soldiers and now she is killed by one of the soldiers.
