 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
