It is now becoming a journalistic cliché to suggest that we live in the postmodernist era. We get to hear politicians and economists continuously referring to post-modern as such that define the realities of today’s living; however, we are rarely being given a definition as to what the term of post-modernism stands for. This can be partially explained by the fact that the application of rational definitions, when it comes to describing the essence of socio-economic dynamics in the modern world, often appears as being out of place. The world is becoming increasingly “multicultural”, when classical economic and political theories that were meant to be utilized within racially homogeneous White societies, are often being deprived of their academic validity, simply because these theories are based on assumption that everybody is equally capable of relying on their sense of rationale when it comes to dealing with various existential challenges. However, as practice shows, people’s racial affiliation does not only define their eating habits, their reproductive abilities and their political worldview, but also the very essence of their existential mode. In his article “Cultures of Reason”, Bruce Bower make it very clear that, for example, people with Asian ethnic background do not think as White people do: “In a variety of reasoning tasks, Asians take a “holistic” approach. They make little use of categories and formal logic and instead focus on relations among objects and the context in which they interact. In short, they direct their attention into a complex, conflict-strewn environment… People in the United States, on the other hand, adopt an “analytic” perspective. They look for the traits of objects while largely ignoring their context” (Bower, p. 57). Thus, we can say that the essence of modern concepts of organizational culture and participative leadership is closely related to the fact that the application of old fashioned managerial approaches, which utilize rationale as its tool, can no longer be thought of as being fully appropriate. In its turn, this has to do with drastic demographical shifts that had taken place in the world, within a matter of last fifty years. The most famous theoreticians in the field of economy and sociology, such as Adam Smith, Max Weber, Emile Durkheim, Karl Marx, George Simmel, Herbert Marcuse etc, were Europeans. At the time when they were working on their theories, the societies in North America and Europe were not being affected by “celebration of diversity”, which is why all classical approaches to managing an organization are essentially the products of White people’s rationale, even though that these approaches often contradict each other. The problem is that people in multicultural societies do not necessarily share the intellectual values, upon which classical socio-economical theories are based. In this paper, we will explore this thesis at greater length, as it will allow us to define guidelines to effective organizational management, within a context of post-modernist realities. In his famous work “The Protestant Ethic and the Spirit of Capitalism”, Max Weber provides us with an understanding of the spiritual foundations of clas
