8 4 DEVELOPMENT AND PURPOSE CHAP. 



some dominating central impulse of the self wherein the 

 desires are either harmonised or controlled. This central 

 impulse is what we call the Will, and it is influenced by 

 the relatively persistent feeling-tone of the self as desire 

 is influenced by the temporary feeling attending its realisa- 

 tion. This relatively persistent feeling-tone is the back- 

 bone of Happiness or Unhappiness, or at least of internal 

 Peace or internal Discontent. 



Thus along with the concept and the processes of explicit 

 reasoning which centre upon the concept there emerges 

 the knowledge of self, and of other beings as persons, the 

 formation of a social tradition, and that organisation of 

 impulse that we know as will. Any one of these involves 

 the rest and is distinctive of the human as opposed to the 

 animal grade of development. 



The world as conceived under these influences soon 

 begins to be a very different world from that which is per- 

 ceived. It is a world not of colours and tones and feelings, 

 but of persons and things, groups and classes, quantities, 

 qualities and relations, the stable fabric prolonged in- 

 definitely into past and future, whose states, phases, 

 attributes, changes make up the world of perception. To 

 the higher development of mind there corresponds a deeper 

 stratum of reality. As at the stage of Assimilation, 

 Reality may be conceived as presenting itself in the form 

 of sense-stimuli charged with feeling, and as at the stage 

 of perceptual correlation it appears as a network of related 

 objects of perception underlying and in a measure explain- 

 ing the stimuli and their attendant feeling, so now it appears 

 as a world of permanence in the midst of change, of 

 uniformity shot through variety which is again to explain 

 the perceptual order. Each advance of intelligence may 

 be taken, on the one hand, as extending our grasp on experi- 

 ence, and consequently our power to direct life, on the 

 other as yielding deeper insight into new orders of reality. 

 The building up of the conceptual order however is a long 

 and gradual process. It is essentially an achievement of 

 the social mind, and the stages of its formation are in a 

 measure recoverable from the examination of the actual 

 movement of human thought. We shall find at least
