This collection includes articles, speeches and fragments from the books of I. Wallerstein, an American sociologist and economist, one of the most authoritative scientists dealing with the problem of world system analysis.

His laws are not "natural," because before there were other societies that lived according to different laws, but in the same way they are not "unnatural" or contrary to human essence, because they worked safely for five hundred years.
