THE PHILOSOPHY OF A SCIENTIST '^ 

 It may be asked what right has a scien- 

 tist to have a philosophy? He spends his 

 days in the study of gross, material things. 

 The geologist busies himself with the earth, 

 the composition and the structure of its 

 crust, the nature of its rocks and other 

 formations, the fossil remains of geologic 

 ages, the elevation of its mountains, and 

 the forces that tend to level the same. 

 These and correlated subjects furnish the 

 material with which his mentality employs 

 itself and upon which it exhausts itself. 

 The astronomer goes further afield and em- 

 ploys his time in the study of the moon, 

 sun and the stars, but all his activities are 

 materialistic. The biologist concerns him- 

 self with the development and modification 

 of the various forms of life. His field is a 

 wide and interesting one. The physicist is 

 engaged in the observation of mass, and 

 the effect of forces thereon. The chemist 

 goes into the atomic structure and arrange- 

 ment of matter. The physiologist is busy 

 with function and the pathologist with ab- 

 normal structure and function. So we 

 might go on enumerating the varied and 

 multiple duties of the scientist, but, after 

 all, his range of activity is confined to 

 material things and what does he know of 

 the higher life? What right has he to 

 interest himself or to offer to speak with 

 any authority on the great problems of 

 life? "What can the scientist know about 

 idealism? Between materialism and ideal- 

 ism there is supposed to be a great chasm, 

 which no man in his right senses would
