The more you use your brain, the more brain you will have to use. 
 - - - George A. Dorsey




A man should keep his little brain attic stocked with all the furniture that he is likely to need, and the rest he can put away in the lumber room of his library, where he can get it if he wants it.
 - - - Sir Arthur Conan Doyle 


I use not only all the brains I have, but all I can borrow.

Hippocrates in his Sacred Disease (from the fifth century B.C.), for
example, asserted that
     "Men ought to know that from the brain, and from the brain alone,
arise our pleasures, joys, laughter and jests, as
     well as our sorrows, pain, grief, and tears, ... It is the brain which makes us mad or delirious ... These things that we
     suffer all come from the brain, including madness." 

"Gentlemen, look on this wonder!    
           Whatever the bids of the bidders,   
           They cannot be high enough for it;   
           For it the globe lay preparing quintillions   
           of years, without one animal or plant;   
           For it the revolving cycles truly and steadily roll'd.   
           In this head the all-baffling brain;   
           In it and below it, the makings of heroes."   
                 - Walt Whitman -  I Sing the Body Electric, 1855


William F. Allman (from Apprentices of Wonder. Inside the Neural
Network Revolution, 1989)
      The brain is a monstrous, beautiful mess.

Santiago Ramon y Cajal 
      As long as our brain is a mystery, the universe, the reflection
of the structure of the brain will also be a mystery.

Santiago Ramon y Cajal 
      The brain is a world consisting of a number of unexplored continents and great stretches of unknown territory.

Daniel C.Dennett (from Consciousness Explained, 1991) 
      The juvenile sea squirt wanders through the sea searching for a
suitable rock or hunk of coral to cling to and make
      its home for life. For this task it has a rudimentary nervous system. When it finds it's spot and takes root, it
      doesn't need its brain any more so it eats it. It's rather like getting tenure. 

Emily Dickinson 
      The Brain-is wider than the Sky-
      For-put them side by side-
      The one the other will contain
      with ease-and You-beside.

Dr. Seuss 
      You have brains in your head.
      You have feet in your shoes.
      You can steer yourself
      any direction you choose.

Dr. Seuss 
      I like nonsense; it wakes up the brain cells.

Barbara Jordan 
      Do not call for black power or green power. Call for brain power.

Thomas L. Masson 
      No brain is stronger than its weakest think.

W. Somerset Maugham 
      The highest activities of consiousness have their origins in physical occurrences of the brain, just as the loveliest
      melodies are not too sublime to be expressed by notes.

Michel de Montaigne (1533-1592) 
      It is good to rub and polish our brain against that of others.

Tom Robbins 
      If little else, the brain is an educational toy.

Carl Sagan (From: Broca's Brain) 
      We are an intelligent species and the use of our intelligence quite properly gives us pleasure. In this respect the
      brain is like a muscle when it is in use we feel very good. Understanding is joyous.
