What I want to demonstrate may appear banal to expert scientist because it does not go beyond knowledge that can be found in good textbooks. But it has relevance beyond science because scientific knowledge is often interpreted falsely, twisted and transformed into ideological statements. This often leads to assertions and adoptions that are absurd from a scientific point of view and highly problematic and even dangerous from a philosophical perspective. Basically, the problem arises from the metaphysical idealization of scientific knowledge, in other words, from the aspiration to explain not only natural phenomena but the whole world through science. This idealization is called (scientistic) naturalism. The writings of the Odum brothers are paragons of that. I will go into that point in the Sections 6.6 and 6.7. The overall purpose of this chapter is to reach some clarification concerning the relevance and applicability of certain ecolongical knowledge in general and the “Odumian” theorioes in particular within a practical context, e.g., landscape architecture.
