Bò đó đã được tống đạt trong hai phần đầu của cuốn sách này là gì? Sau chuyến tham quan dài thông qua các vấn đề khác nhau và các khái niệm sáng tạo đó đã dẫn chúng ta qua các cuộc tranh luận triết học và phát triển khoa học sáng tạo rất cũ, đó là thời gian để có được trở lại với mục tiêu ban đầu của này và làm thế nào là vật liệu trình bày và thảo luận cho đến nay trong cuốn sách này có liên quan cho những người sẵn sàng để. | Part 3 Complex Systems Thinking in Action Multi-Scale Integrated Analysis of Agroecosystems 2004 by CRC Press LLC Introduction to Part 3 What Is the Beef That Has Been Served in the First Two Parts of This Book After this long excursion through different issues and innovative concepts that has led us through very old philosophical debates and innovative scientific developments it is time to get back to the original goal of this book. Why and how is the material presented and discussed so far in this book relevant for those willing to study the sustainability of agroecosystems Part 3 provides examples of applications aimed at convincing the reader that the content of Parts 1 and 2 is relevant indeed to an analysis of the sustainability of agroecosystems. Before getting into such a presentation however it could be useful to have a quick wrap-up of the main points made so far 1. Science deals not with the reality but with the representation of an agreed-upon perception of the reality. Any formalization provided by hard science starts from a given narrative about the reality. That is any formalization requires a set of preanalytical choices about what should be considered relevant and on what time horizon. These preanalytical choices are value loaded and entail an unavoidable level of arbitrariness in the consequent representation. Substantive models of the sustainability of real systems do not exist. 2. To make things more difficult science dealing with sustainability must address the process of becoming of both the observed system and the observer. This implies dealing with an unavoidable load of uncertainty and genuine ignorance which is associated with the existence of legitimate nonequivalent perspectives found among interacting agents. 3. The process of generation of useful knowledge is therefore a continuous process of creative destruction.
