HIGHER FUNCTIONS 189 



Most of the New World Monkeys live in small com- 

 munities, nevertheless the family unit is long maintjiincd 

 in some forms {Lagothrix, etc.), and in some is said to be 

 permanent {Pithecia). 



Amongst the Lemurs conditions vary greatly. Some 

 live in small groups, but the majority remain isolattni in 

 pairs, or limited to family parties. Very little of the 

 intimate details of their lives has been studied, but 

 Tarsius spectrum definitely " lives in pairs " (Hose), and 

 so does Nycticebus tardigradus. 



If higher ideals of conduct are admitted tu Ijc mere 

 extensions of a natural cerebral evolution of wliich so 

 many other developments are certainly known, it w ill be 

 under such conditions as those we have been })icturing 

 that they will be called into being. If higher ideals of 

 conduct are to be acquired as an evolutionary process, 

 it is in the family circle that their rudiments will l)e laid 

 down, and it is in the family circle and in the society 

 composed of families that these rudiments will be per- 

 fected.
