38 From Matter to Man. 



its motion. Separate matter from motion and you 

 divorce matter from itself. It could not even exist in 

 this malformed condition. It would, further, be in- 

 describable, for its indestructibility, hardness, size, 

 shape, etc., all involve conditions which are the result 

 of change of place induced by its motion. Scientists, 

 accordingly, have framed the molecular theory, which 

 enunciates that matter, even in solids, is perpetually 

 moving, one common illustration being the con- 

 tinual contraction and expansion of such a seemingly 

 rigid substance as iron. 



Although matter and motion are thus inseparable 

 in practice, yet in theory each has its own laws. 

 Hence the duty of the scientist is to discover what 

 these laws are. For which see anon. 



Section 5. Cause, or the Creator of the Things of 

 Existence : 



Cause in natural operations has been usually held 

 to imply intentional cause, hence the conception of a 

 personal Creator. But a more accurate investigation 

 into the transformations of the universal kaleidoscope 

 reveals two distinct kinds of causes. 



(a) Cause by intention through lazu. — An occurrence 

 actually happening by automatic laws, but brought 

 about by design or intention in an organism which 

 overrules these laws, i.e., when a man breeds a new 

 variety of cat or dog. 



(b) Cause by accident through latv. — An occurrence 

 happening by automatic laws acting fortuitously, or
