PHYSIOLOGICAL, REGULATIONS 



Whatever the specific manners in which each functional state 

 of a living unit is preserved, each state is definable in no uncertain 

 terms. All processes that are found to contribute to or detract 

 from this preservation are concerned in regulations. Perhaps 

 most or all that happens in organisms will be found to be such.

§ 158. Classification 



Further understanding of regulations may be gained by at- 

 tempting to classify them in additional ways. As in the past, 

 meaningless (insoluble) propositions may be avoided by appealing 

 in each classification to the procedures of measurement. 



(1) Each component found in an organism, and every pro- 

 cedure of measuring it, might be said to identify a regulation 

 toward whose maintenance or avoidance the organism is working. 

 To the organism each component would perhaps hardly seem to be 

 a discrete entity; to the investigator there is no more direct way 

 of dealing with a regulation than by measuring the corresponding 

 component. Since measurement of whatever is being regulated 

 implies dimensions, components themselves may be classified ac- 

 cordingly. No cognizance is here taken of possible physical proc-
