 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
