 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
