CLASSIFICATION OF SCIENCES 93 



stract Sciences include Logic and other "method- 

 ological " disciplines, and mathematics with its 

 many subdivisions including Statistics. 



The Concrete Sciences include (1) the Phys- 

 ical Sciences, which deal with inorganic phe- 

 nomena, and (2) the Biological Sciences, which 

 deal with organic phenomena. The Physical 

 Sciences are divided by Pearson into the Precise 

 and the Synoptic, the latter always decreas- 

 ing as the former increase. Astronomy is in 

 greater part precise, meteorology is in greater part 

 synoptic. "In the one case we have not only a 

 rational classification of facts, but we have been 

 able to conceive a brief formula, the law of gravi- 

 tation, which accurately resumes these facts. We 

 have succeeded in constructing, by aid of ideal 

 particles, a conceptual mechanism which describes 

 astronomical changes. In the other case we may 

 or may not have reached a perfect classification 

 of facts, but we certainly have not been able to 

 formulate our perceptual experience in a mechan- 

 ism or conceptual motion, which would enable us 

 to precisely predict the future." 



(1) THE PHYSICAL SCIENCES those dealing 

 with Inorganic Phenomena are divided by Pear- 

 son into the following: 



Precise Physical Sciences (reduced to ideal 

 motions) .
