heart, blood-vessels, lungs and respiratory apparatus, 

 digestive organs, glands, skin, and so forth. 



5. From the organs thus innervated and called into 

 activity, there proceed ingoing currents to the sensorium. 

 These afford the primary data of the states of conscious- 

 ness termed emotions. And these data are linked by 

 association with those given by the special senses, and by 

 motor responses. The emotions are instinctive in that 

 the co-ordinated outgoing currents are of like nature with 

 those concerned in instinctive response. 



6. The data of consciousness are all of afferent origin, 

 and any of them, whether sensory, motor, or visceral in 

 origin, may be either pleasant or painful. 



7. The power of association by which the data of 

 consciousness are linked in experience so that on the 

 recurrence of certain data, a revival in memory of other 

 associated data is rendered possible is innate. Innate 

 also are susceptibilities to pleasure and pain. 



8. Accompanying the functional activity of the higher 

 brain centres, called into play by incoming currents, is a 

 control over the lower centres, exercised through augmen- 

 tation or inhibition of their automatic action, in the light 

 of experience. This again is innate. 



9. Acquired activities are those the definiteness of 

 which is reached by the exercise of control. 



10. The term "congenital" is applied to inherited 

 definiteness of response in instinctive behaviour, reflex 

 action, or the distribution of innervating currents to the 

 viscera; the term "innate," to inherited faculties, and 

 susceptibilities to pleasure and pain. Instinctive definite- 

 ness is congenital and prior to experience. Acquired 

 definiteness is due to experience, and is rendered possible 

 by innate faculties and susceptibilities. 



11. The frequent repetition of acquired activities gives
