The paper analyzes the function of values, systems of values or of the 'teleological world' and their impacts on the life of man and society. This function is connected with the structure of social action, its goal orientation together with its rationality. The action is based on decision-making procedures. The decision-making represents a choice between alternatives, which is based on their evaluation, assessment other proceeding from values, criteria or criterial functions. The role of values is bound to evoke value-related attitudes connected with the selection, preferences or comparisons. It is not possible without integrating values and knowledge.
