theory, the chief task performed by social systems is to reduce complexity, which brings more choices and more possibilities; it takes more noes to reach a "yes". Religion or functional equivalents in modern society can provide actors with shared standards of action accepted on faith, which allow complex sets of interactions to proceed in a world that would otherwise be chaotic and incomprehensible. Furthermore Luhmann makes the distinction between risk, a potential harm threatening an individual that is based on a decision made by the individual, and danger, a potential harm to which an individual is passively exposed. The critical difference between the decision maker and the people affected by the decision is that what is a risk for one is a danger for the other. Whereas people in primitive societies were threatened primarily by dangers, people in modern society are threatened primarily by risks caused by our dependency on the decision makers.
