 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
