making any farther transit from this bone to the common sense, where  
the voice confers with and discourses to the common judgment. The  
sense of smell, again, is compelled by necessity to refer itself to  
that same judgment. Feeling passes through the perforated cords and  
is conveyed to this common sense. These cords diverge with infinite  
ramifications into the skin which encloses the members of the body  
and the viscera. The perforated cords convey volition and sensation  
to the subordinate limbs. These cords and the nerves direct the  
motions of the muscles and sinews, between which they are placed;  
these obey, and this obedience takes effect by reducing their  
thickness; for in swelling, their length is reduced, and the nerves  
shrink which are interwoven among the particles of the limbs; being  
extended to the tips of the fingers, they transmit to the sense the  
object which they touch.  
The nerves with their muscles obey the tendons as soldiers obey the  
officers, and the tendons obey the Common [central] Sense as the  
officers obey the general. [27] Thus the joint of the bones obeys  
the nerve, and the nerve the muscle, and the muscle the tendon and  
the tendon the Common Sense. And the Common Sense is the seat of the  
soul [28], and memory is its ammunition, and the impressibility is  
its referendary since the sense waits on the soul and not the soul  
on the sense. And where the sense that ministers to the soul is not  
at the service of the soul, all the functions of that sense are also  
wanting in that man's life, as is seen in those born mute and blind.
