 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
