Brotherhood and the Struggle for Existence

In Steiner's lecture Brotherhood and the Struggle for Existence, he briefly mentions about past scientific evidence in relation to struggling for existence. A Russian scientist named Kessler had showed that the animals capable of development and become truly progressive are not the ones that do the most fighting, but those that give mutual support to one another, that help each other. Struggle is present but the question becomes what furthers development more: warfare or mutual assistance? Peter Kropotkin, an anarchist, wrote a book entitled Mutual Help in the Animal Kingdom and Human Life which provides evidence that mutually assistance leads to progress instead of fighting.
The struggle for existence has its place in the world. It takes a certain amount of egoism to develop our talents and to take initiative but if we do not work on ourselves and develop our talents, we will be poor helpers.
Survival of the fittest is a complete myth. Many people are strong in one area and weak in others. Who determines what is strong and what is weak? It is all dependent on perspective. What I may perceive within myself as a weakness may from another more wiser perspective may be my greatest strength.
When I watch these reality shows, like say the Apprentice, it becomes quite evident that the teams that do well are the ones that make an effort to put their ego aside and work together inside of fighting.
I think it's great that we all have egos but it's also important that we can put it aside and forget about ourselves.
Brotherhood and the struggle for existence are 2 distinct streams that work in humans. We must recognize that within individuals there is something that yearns for both individuality and brotherhood/community. Neither must be denied and both must be developed.
