3o8 The Theory of Geitetic Modes 



are adequate, they reflect earlier stages in the unfolding 

 of the same system. But the ' arming ' is inadequate for 

 full interpretation, since it is forged in the fires of the past. 

 The ideals, the values yet in process, and always to be 

 in process, of achievement, get their impelling power from 

 the very experience that knowledge and life are functions 

 of a genetic process of which our formulated realities are 

 passing phases. 



This might be carried out in a philosophical view of 

 reality, — a theoretical doctrine of metaphysics, — but that 

 is not my intention here. The only safe course for 

 science, however, is to recognize these things. Genetic 

 science is competent to m.ake the reservation always, in 

 the presence of each of the applications and explanations 

 of exact and numerical science, that it is a cross-section^ 

 not a longitudinal section, to which the quantitative and 

 analytical formulas apply ; or that, if they apply through- 

 out a serial process, — as in a series of successive trans- 

 formations of energy, — that is proof that the process in 

 that case is not a gejtetic one. It is the genetic aspect, we 

 must hold in such cases, which has escaped the formula; 

 the success of the quantitative and analytic methods is 

 itself the evidence that no really genetic movement has 

 occurred out of the natural aspects of things ; in other 

 words, only those have been taken which illustrate the 

 repetitions, not the adaptations, of nature. 



§ 4. Genetic Science 



We may undertake, in view of these considerations, to 

 state the actual relation which we are justified in holding 

 to subsist between exact or agenetic science, so-called, on 

 the one hand, and genetic science, on the other hand.
