 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 
 On  Your  Technique,  You  Might  Easily 
             Find Recurrences.
