 quite as consistent with ordinary virtue and effective- 

 ness to accept these as objective realities, as it is to 

 have the vague faith in microbes and molecules, mahat- 

 mas and protoplasm, in protective tariffs and mani- 

 fest destiny, which form part of the mental outfit of 

 the man of our day. Unless these ideas are brought 

 into terms of personal experience, they can not be

 safety of gregarious creatures. 



With all this, the growth of each individual must be 

 determined by his own experience. About the sense- 

 impressions formed in my own brain I must build up my 

 own universe. Thus it comes that each accretion of 

 human knowledge must be thrown into terms of our pre- 

 vious experience. Stated in these terms, it is always
