it tempts the other party. The other hand is extended in 
demand toward the object which is desired in exchange. The 
first hand lets go as soon as the second object is touched, 
somewhat in the manner of a trapeze artist exchanging one 
bar for another. In fact, Elias Canetti in Crowds and Power  
argues that the trader is involved in one of the most ancient of 
all pastimes, namely that of climbing trees and swinging from 
limb to limb. The primitive grasping, calculating, and timing of 
the greater arboreal apes he sees as a translation into financial 
terms of one of the oldest movement patterns. Just as the 
hand among the branches of the trees learned a pattern of 
grasping that was quite removed from the moving of food to 
mouth, so the trader and the financier have developed 
enthralling abstract activities that are extensions of the avid 
climbing and mobility of the greater apes.
