sense-impulses, and lay down generally that assimilative 

 experience postulates sensations and feelings as its data, 

 and produces modified sense-feeling and acquired sense 

 impulse, passing into habit, as its result. 1 



10. Thus through the agency of assimilation a mass of 

 grouped experiences sensation, motor response, and 

 feelings, have an effect on the organisation of such a kind 

 that response is subsequently modified according to the 

 nature of the feeling. There is then a certain correlation 

 between a mass of related experiences and subsequent 

 reactions. To the observer it is clear that the basis of this 

 correlation is the relation of stimulus, reaction, and feeling 

 in the primary experience, and that in the subsequent 

 response the conation is correlated with, i.e., is executed 

 so as to produce the result. But in the type of action 

 before us the elements are not distinguished nor the 

 relations grasped by the agent as they are by the observer. 

 The action of the moment is related in one sense to the 

 past, in another to the future, but in both senses without 

 consciousness of the relation. At no point have we 

 successive elements of experience and action distinctly 

 grasped and articulately correlated. We have rather the 

 result of the earlier experiences as a whole determining 

 the result, /".*., the response, in the later experience. We 

 may describe this as a correlation of Empirical Results, or 

 negatively and cursorily as Inarticulate correlation. 



Whether any animals other than man advance to a more 

 articulate correlation is a question depending on the 

 experimental application of delicate tests. To explain the 

 nature of articulate correlation, to describe the behaviour 

 tests from which it may be inferred, and to discuss whether 

 there are any species of animals to which it may be 

 attributed, will be the work of Chapters VIII-XII. 

 For the present we are content to note that there is 

 abundant evidence for the existence of the elementary kind 

 of correlation, on which human perceptions and perceptual 

 impulses are based, far down in the animal scale. Whether
