sx. SYMBIOGENESIS 



indeed, of every organism or species in the light of sym bio- 

 genesis, i.e., of their symbiotic usefulness or the reverse in 

 progressive evolution. Here, then, we have a means of deter- 

 mining what a French writer (Bougie) terms " les volontes de 

 la nature" " le critere objectif du bien et du mal." Here 

 we have at last a valid measure of biological status and at the 

 same time a sound basis for a rational system of evolutionary 

 ethics so sadly needed in these latter days of doubt and 

 confusion. 



In the first place, it is necessary to distinguish between 

 those biological dynamics which go to establish physiological 

 capital and those which have the contrary effect. In view of 

 the fundamental importance of symbiosis biological 

 symbiosis largely determines the value of " domestic " 

 symbiosis, as shown in Chapter I. I have coined the terms 

 symbiotics and antibiotics, the former to denote those specific 

 ancestral activities calculated to enrich the organic world 

 and, concurrently, the species itself, the latter to denote the 

 ojiposite (anti-social) activities which may be seen in the long 

 run to impoverish a species as they also tend to arouse various 

 forms of biological antagonism and of nemesis. 



The symbiogenetic view thus enables us to introduce into 

 Biology a kind of applied dynamics, Bio-Dynamics, as I have 

 termed it on the analogy with Bio-Chemistry, which latter is 

 likewise, as I have endeavoured to show in this and previous 

 volumes, receiving a new setting in the light of symbiogenesis. 



Thus equipped with a reliable standard of biological values 

 un metre du progres and with reliable bio-dynamic 

 methods, we can undertake the study of genetics far more 

 satisfactorily than has hitherto been possible. 



It is the blending of matured reciprocal values that 

 we are concerned with in genetics. This blending, of 

 course, requires more than mere maturation of values. 

 It requires a distinctly co-operative (symbiotic) disposi- 

 tion and preparation on the part of all those units 

 more specially concerned in the blend. To be effective this
