160 UNIVERSAL EVOLUTION 



order and degree. The idea lasts while the waves of 

 molecular motion last, ceasing when they cease; but 

 that which remains is the set of plexuses." This means 

 that the nervous structure in the brain, which has been 

 evolved biologically, is the permanent determinant of 

 ideas. Therefore the laws of evolution apply to 

 psychical, as well as to physical phenomena. 



ORGANIC PRESERVATION. Every so-called action of 

 the will, and every psychical action, e. g., every thought, 

 is determined either by the preservation of self or of 

 the race. 



This is the meaning of life. It is an adjustment of 

 the organism to the source of its preservation viz.. its 

 physical environment. Therefore, the law of evolution 

 in physical biology, which is the preservation of the 

 individual and the race, must apply to all forms of 

 psychical phenomena 



As SAID BY RIBOT: "Sensation" (which produces 

 the thought) "is a monitor, an aid, an instrument, a 

 weapon, with only one aim, the preservation of the 

 individual. ***** 



The nexus between the sensations, and the organic, 

 and motor reaction is, therefore, innate." This means, 

 it is function of matter. This sensation may come from 

 within the organism, but that does not make it 

 necessarily subjective, but objective. The molecular 

 motion within the brain may be the sensation causing 

 other forms of molecular motion in the same brain, or 

 thought producing thought, but it nevertheless has a 

 physiological mark, the same as sensations coming from 

 without the organism. 



ADVOCATES OF INDEPENDENCE. The advocates of in- 

 dependence do not tell us what it is that produces 

 the thought, but seek to measure by instrument the
