208 UNIVERSAL EVOLUTION 



by the phenomena of nature and life." (Joseph 

 Dietzgen. ) 



To common sense, there exist two things self and 

 not-self. The scientist knows they are one, but, in 

 practical every day activities, they must be treated as 

 two. Of course, the unscientific do not always see 

 the "not-self" correctly. Otherwise mankind would 

 not be deluded, or illuded. But suppose one should 

 discard the use of his senses, and depend entirely upon 

 what the idealist calls intuition, under the old defini-

 facts, most, if not, all the time. In that case, the world 

 would still be inhabited by ghosts, and the light of 

 the sun, and stars, and the blue of the sky, would 

 still be shut out by innumerable forms of angels and 

 hobgoblins. 



"The notion that truth external to the mind may be 

 known by intuition, or consciousness, independently of 

 observation, and experience, is, I am persuaded, in these 

 times, the great intellectual support to false doctrines, 

 and institutions. By the aid of this theory, every 

 inveterate belief, and every intense feeling, of which 

 the origin is not remembered, is enabled to dispense 

 with the obligation of justifying itself by reason." (John 

 Stuart MilU 



The intuitive theory adopted, for its main support, 

 the evidence of Mathematics, and the cognate branches 

 of physical science. But Mill's "System of Logic" at- 

 tacked this support, and sought to show that these 

 sciences are, also, inductive. They are strictly material. 



"Our ideas and concepts, and scientific theories pass 

 for true only so far as they harmoniously lead back to 

 the world of sense." (William James.) So that
