tion, and structure. All these are present in 

 the simplest forms of multicellular life, rhythm 

 being the objective expression of a continuous 

 consciousness. Motion is likewise the objec- 

 tive expression of pleasure, and structure is a 

 like expression of memory. Such an organism 

 could perpetuate itself so far as its own condi- 

 tions were concerned, but it would be at the 

 mercy of any adverse objective change. With- 

 out sensations, no adjustment and no avoidance 

 of external evils are possible. As soon as the 

 interests of different organisms come into con- 

 flict, the acquisition and development of sensa- 

 tions begin ; but they must develop along the 

 lines of the struggle for consciousness, and 

 utilize the material it furnishes. All the ele- 

 mentary forces are already in play. The prob- 

 lem is to use them to secure a content, as well 

 as a continuity, for consciousness. 



To show how this is wrought, I will again 

 say that all structure is the result of motion, 

 and that simple structure directly subserves 

 the subjective end of sustaining consciousness, 

 and indirectly, the objective end of creating 

 movements. The struggle for consciousness
