"Our final conceptual remark is also in order. As we pointed out above, the Newtonian paradigm has no room for the category of final causation. This category is closely tied up with the notion of anticipation, and in its turn, with the ability of systems to possess internal predictive models of themselves and their environments, which can be utilized for the control of present actions. We have argued at great length above that anticipatory control is indeed a distinguishing feature of the organic world, and developed some of the unique features of such anticipatory systems. In the present discussion, we have in effect shown that, in order for a system to be anticipatory, it must be complex. Thus, our entire treatment of anticipatory systems becomes a corollary of complexity. In other words, complex systems can admit the category of final causation in a perfectly rigorous, scientifically acceptable way. Perhaps this alone is sufficient recompense for abandoning the comforting confines of the Newtonian paradigm, which has served us so well over the centuries. It will continue to serve us well, provided that we recognize its restrictions and limitations as well as its strengths."[bold added]
