"The power of the individual human being is not sufficient for him to obtain (the food) he needs, and does not provide him with as much as he requires to live. Even if we assume an absolute minimum of food...that amount of food could be obtained only after much preparation...Thus, he cannot do without a combination of many powers from among his fellow beings, if he is to obtain food for himself and for them. Through cooperation, the needs of a number of persons, many times greater than their own number, can be satisfied."
