"In fact, communism is the foundation of all human sociability. It is what makes society possible. There is always an assumption that anyone who is not an enemy can be expected to act on the principle of "from each according to their abilities," at least to an extent: for example, if one needs to figure out how to get somewhere and the other knows the way. We so take this for granted, in fact, that the exceptions are themselves revealing. E.E. Evans-Pritchard, an anthropologist who in the 1920s carried out research among the Nuer, Nilotic pastoralists in southern Sudan, reports his discomfiture when he realized that someone had intentionally given him wrong directions: On one occasion I asked the way to a certain place and was deliberately deceived. I returned in chagrin to camp and asked the people why they had told me the wrong way. One of them replied, "You are a foreigner, why should we tell you the right way? Even if a Nuer who was a stranger asked us the way we would say to him, 'You continue straight along that path,' but we would not tell him that the path forked. Why should we tell him? But you are now a member of our camp and you are kind to our children, so we will tell you the right way in future."12"
