 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
