 Feedback  Is  For Making  The  Process A 
 Whole  Lot  More Messy,  To Introduce  A 
 Fractal  In  The Spice Mix...  Things Or 
 Populations  Of Things Start To  Be Self 
        Referential Or Self Eating        
 (AutoVore...) Or SpiralIng In  Or Out... 
                                          
 In The Sixties They Did Research In  The 
 Jungle And In  The  Sea  And They  Found 
 That  Feedback  Does Not Give Rise To An 
 Equilibrium. They Were  Trying To  Prove 
 That Nature Is A Tame Beast.  But  She'S 
                   Not!                   
 This  May  Hold  True Out  There...  But 
 Maybe Not In Signal Wizardry?  Depending

            Find Recurrences.
