II48 LIFE : OUTLINES OF GENERAL BIOLOGY 



Yet since living beings have need of external energies as well as 

 of matter, we see that we can do better by introducing both at the 

 outset, as ME for matter and energy (a change for which the pre- 

 ceding graph so far prepares us) so ME, L, T. 



ME 



meL 



meT 



IME 



IT 



tME 



tL 



That Matter and Energy are essential to Life, is here re-expressed 

 as meL, and that Life is ever incorporating them into itself, so 

 vitalising them, is IME. That this latter is a timed process, tME is 

 plain for all living beings, as by day and night, in nature's seasons, 

 etc.. Next, that Life is timed, tL, is manifest for all its phases, from 

 earliest to death. What then is IT? Life modifying Time, en-lifting 

 it, if we may so speak. Is not this Bergson's "Duree", which we 

 have seen to be so characteristic of living things ; and also incipient 

 in animal societies, and so developed in our own? It seems now plain 

 that this three- to nine-fold form of graph — first devised for the 

 clearer treatment of the interrelations of Organism with its Environ- 

 ment, and of Place with its People — is also applicable towards clear 

 and simple arrangement of the main concepts of physical and even 

 mathematical science ; and one which readily may be carried further 

 than in the above outlines; so more and more fully justifying what 

 Mr. Whitehead so rightly urges, that organismal conceptions are 

 needed in physical science.
