34 THE BIOCOSMOS GENERAL INTRODUCTION. 







one-sided in fact, and will have a recurrence 

 to his presence, for Physis, too, belongs to 

 the Universe. 



Now it is this Psyche which gives the chief, 

 yea, the insurmountable trouble to the biolo- 

 gist, always pushing into his horizon, yet al- 

 ways escaping him when he tries to grip her 

 or to witness her secrets with that cunning 

 magnifying eye of his. At present biologi- 

 cal division seems to be the grand mystery, 

 springing from some inscrutable source; the 

 cell divides, the nucleus divides, so does the 

 nucleolus and the protoplasmic granule, yea, 

 even the hypothetical biospore (Weissmann), 

 pangen (De Vries), biogen (Verworn). For 

 the self-separation of the germinal principle 

 has to take place: but why and whence? 



Of course such an ultimate division in its 

 source carries us out of Life to its determi- 

 nant, which is psychical. It is important to 

 note in this connection, that Biology has be- 

 gotten its counterpart, Physiological Psychol- 

 ogy whose title couples the twin elements 

 already mentioned, Physis and Psyche. This 

 new science takes for granted the immediate 

 unity of the physical and psychical elements 

 in the total evolution of Life since its first

 act, so we behold in this field an experimental
