I would beg to differ with this, because of specific stories that place the human spirit far above the sum of its physical parts. I read a document by Jewish captives I a Nazi camp once. They went through the most terrible of physical hardship. There was no food, or food was at least inadequate. There was not sufficient health care, and, for most inhabitants, they have been separated from friends, family, and even acquaintances. By theories such as that of Maslow, these people should have become feral animals, fighting like dogs for the little food they were provided with.

But, according to the story I heard, this was not so. According to my story, the feeling among the Jews was that their humanity was the last bit of dignity that they could hold on to. They shared everything. If a person was hurt or died, they took care of the wounded and buried the dead. They comforted those who lost loved ones and shared their food as equally as they could. The question is why did they do this? According to the account I read, they did this not only for the sake of their humanity, but for the sake of staying alive. According to one account, the person who took even one berry more than they were allocated according to fair distribution would soon be dead. Those who lived longest were those who shared among each other, and those who developed caring relationships.

This story shows that, even I the worst physical circumstances, it is the human spirit of camaraderie, sharing and caring that prevails. Those who live their lives according to a war, hatred, and death have such a devastating effect on our society and culture. As human beings, we not only need to be loved, but we also need to return that love. The Jews in the concentration camps understood this, and many survived because of it. Today, we understand it in a much wider context.
In terms of work and human relationships, people live on the basis of love and being loved in return. This is something the Jews understood in the Nazi camps: to truly survive in this world, it is necessary to work together. Those who live and work by themselves have a lower chance of survival than those who work together.

In conclusion, humanity today seems to understand that there is a collective sense of working together that helps us to survive as a species. This is also why we tend to focus on finding life partners and friends to combat loneliness and isolation. In general, humanity needs cooperation. While not all managers and groups have understood this over time, it has been a truth that has survived centuries of human history.
