PSYCHOGENESIS 379 



operations. That the bio-economic and physiological opera- 

 tions of " organic civilisation" have throughout their psycho- 

 logical parallels and concomitants must now be clear. It is 

 also now patent that we must seek to progress in the " art of 

 feeling" quite as much as in every other bodily or mental art, 

 in order to obtain the blessings of an enhanced symbiogenesis. 

 Juvenal, that greatest of Roman " correctores," has expressed 

 a similar thought : 



Mollissima corda 



Humano generi dare se natura fatetur, 



Quae lacrimas dedit. Haec nostri pars optima sensus. 



Juvenal uttered these words as a protest against the 

 inhumanities of his time "cum in servum omnia liceant " ! 

 The time has now arrived for a more enlightened age to 

 recognise not only the claims of down-trodden humanity, but 

 also those of other down-trodden members of " organic civilisa- 

 tion." The law of compassion has long been preached. I 

 submit that it can now be supplemented in the light of symbio- 

 genesis, and be shown to be above all a Law of Nature.
