 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 
 On  Your  Technique,  You  Might  Easily 
             Find Recurrences.
