selves strictly to the evidence presented by known 

 and demonstrable facts, then we must regard 

 mind not as a self-sustaining entity, but rather as 

 a property or attribute of living matter. 



Mind is synonymous with self-consciousness 

 because whatever can be said of the mind can also 

 be said of the self-consciousness. Without mind 

 or self-consciousness we can have neither sensa- 

 tion, thought, memory, or volition. 



The individual self-consciousness is coexten- 

 sive with the central nervous system. Most of the 

 cells of our bodies form parts of us physiologi- 

 cally but not mentally. In order for a cell to form 

 part of us physiologically it is only necessary for 

 the cell as a whole to be definitely coordinated in 

 position and specifically related in function to the 

 other cells of the body, but in order to form part 

 of us mentally it must be coordinated with the 

 cells of the central nervous system on a molecular 

 scale, that is, its individual spirazines must be 

 coordinated with or joined to those of our central 

 nervous system in a specific manner, so that elec- 

 tric impulses passing along a certain spiral or 

 polygonal compartment of on^ of these cells will 

 be transmitted to a certain spiral or polygonal 

 compartment of the other instead of being dissi- 

 pated and lost in the surrounding protoplasm.
