 may be reflex, tropistic, instinctive; for Man it must be 

 intelligent, at least; rational, if possible. But what the evolu- 

 tion-process points to with firmness is that Brains pay 

 Brains that include Love as well as Logic. 



2. Heredity the First Determinant of Life. 



The first determinant of life is the natural inheritance

 coercion are over, but there is no coercion in the garrisoning 

 (probably most effective when least direct) of the affections
