"There is neither happiness nor unhappiness in this world; there is only the comparison of one state with another. Only a man who has felt ultimate despair is capable of feeling ultimate bliss. It is necessary to have wished for death in order to know how good it is to live." 

Excerpt from Elie Wiesel's Night. One of the most powerful pieces of text I have ever read. 

"The road was endless. To allow oneself to be carried by the mob, to be swept away by blind fate. When the SS were tired, they were replaced. But no one replaced us. Chilled to the bone, our throats parched, famished, out of breath, we pressed on. 

We were the masters of nature, the masters of the world. We had transcended everything - death, fatigue, our natural needs. We were stronger than cold and hunger, stronger than the guns and the desire to die, doomed and rootless, nothing but numbers, we were the only men on earth." 

Excerpt from Lennard Bickel's Mawson's Will

Mawson located the glacial grave with some precision: "It is 35 miles east-southeast of the headland which I named Cape Freshfield; 15 miles from this charted camp." And his mind was on the dogs, already near starvation and complete exhaustion. "Winter quarters are 300 miles away, and we shall not get through unless we eat the dogs. We are terribly handicapped." He pondered their plight and the fearful struggle that lay ahead of them. "May God help us."
