THE CONFLICT OF SCIENCE 109 



evolution has gone on psychical evolution ; side 

 by side with the evolution of organs and tissues 

 has gone on the evolution of intellect, sensibility, 

 and will. Human nature and human mind are 

 no more stii generis than are human anatomy and 

 physiology. The same considerations that prove 

 that man's material organism is the cumulative 

 result of long evolution proclaim that human 

 mind, the immaterial concomitant of the material 

 organism, is also the cumulative result of long 

 evolution. 



We might just as well recognise facts first as 

 last, for they will have to be recognised some time. 

 Truths are not put down by inhospitality — they 

 are simply put off. The universe has a policy, a 

 program. We may close our eyes to the facts 

 around us, hoping in this way to compel them to 

 pass away or be forgotten. But they do not pass 

 away, nor will they be forgotten. They simply 

 become invisible. They will live on and present 

 themselves to other minds or ages or climes more 

 hospitable or honest than our own. The only 

 proper attitude of mind to assume toward the 

 various doctrines existing among men is the 

 attitude of perfect willingness to believe anything 

 — anything that appeals to us as being reasonable 

 and right. The great majority of men, however, 

 are intellectual solids — unable to move and un- 

 willing to think. The}^ have certain beliefs to which 

 they are determined to hold on, and everything that 

 does not fit in with these beliefs is rejected as a 

 matter of course.
