60 THE ANATOMY OF SCIENCE 



quately; but the concept of time is so very 

 fundamental that we shall meet it in several of 

 these chapters, and it will be one of my most 

 interesting tasks to analyze the scientific notion 

 of time and to attempt to resolve this complex 

 into its components. 



In order to create a science out of a great 

 body of freely growing thought, it is necessary, 

 first of all, to eliminate as far as possible the 

 human and subjective elements, and such a step 

 was taken by our remote ancestors when they 

 decided to measure the lapse of time, not by 

 their ot\ti feelings, but by the movements of the 

 earth and moon. Indeed, with all our inventive- 

 ness we have yet to make a chronometer more 

 accurate than these. 



A study of the motion of bodies leads us into 

 the science of kinematics, which is evidently 

 something broader than geometry, since it in- 

 cludes all of geometry and the element of time 

 as well. Philosophers have always included 

 space and time as cognate abstractions, but 

 that the partnership between them is an indis- 

 soluble one was, I think, first perceived by Leib- 

 nitz, whom we have already quoted as saying, 

 "Space is the order of coexisting things," and 

 who elsewhere said, "But space and time taken
