THE SCIENCE OF HAPPINESS 



Mind, the sentient being, listening to the message that 

 the complex apparatus brings from the outer world. 

 Every part of this apparatus must be in good working 

 order, or the message will either fail to come at all to 

 the mind, or will be a distorted one. 



To make the comparison complete, it must be known 

 that the brain-cells that thus receive messages from 

 without are also in constant communication with one 

 another through the medium of a vastly complex 

 network of fibres that merely pass from one cell to an- 

 other, without extending beyond the confines of the 

 brain. Thus the messages received from one source 

 are constantly checked, as it were, by comparison with 

 messages from other sources; such association being 

 equally essential to the development of correct inter- 

 pretations of the various and sundry messages. By 

 means of the apparatus of associational fibres and cells, 

 it is possible also to send out messages from the brain 

 to the periphery of the body, along another set of 

 exterior wires, ordering certain sets of muscles to con- 

 tract, to meet what the mind conceives to be the needs 

 of the body. 



Such, then, is the physical sub-structure beneath 

 the mind. Such is the apparatus that must functionate 

 in order that the curious process we call thinking may 

 be effected. But, after emphasizing thus the inter- 

 dependence of mind and body, we may revert to the 

 earlier point of view to the extent of reaffirming that, 

 after all, the brain and the body in which it rests are of 

 no importance in and for themselves. They are solely 

 important as being the dwelling-place of the mind.
