However, granted these permanent difficulties, 

 there are others which may be reduced or made to 

 disappear. Granted that we have to organize our 

 minds into a whole, we can see the general plan on 

 which we should aim at organizing it. We must 

 aim first at having no barriers between different parts 

 of the mind. Every attempt must be made in the 

 education of children to prevent there being a stigma 

 attached to one whole section of mental life, and so 

 to avoid its partial or total dissociation from the rest. 

 On the other hand, the absence of barriers does not 

 imply the absence of any relation of subordination or 

 dominance of one part to another. One of the 

 most important biological generalizations is that 

 progressive evolution is accompanied by the rise of 

 one part to dominance and, whenever there are many 

 parts to be considered, by the arrangement of the 

 rest in some form of hierarchy, each part being 

 subordinate to one above, dominant to one below. 

 It is such a hierarchy which we must try to construct 

 in our mental organization. 



It is obviously impossible here to go into the whole 

 question of values and ideals, but it is clear to any one 

 who has given the briefest reflection to the subject 

 that there are certain values, aesthetic, intellectual, 

 and moral, which are ultimate for the mind of man, 

 certain ideals — of truth and honesty, intellectual 

 satisfaction, righteousness or at least freedom from the 

 sense of sin or guilt, completeness and self-realization.
