HUMAN CONTROL 



We know something of the physical and 

 chemical processes involved in muscular 

 contraction, in nervous conduction, and in 

 thinking. It is true that our knowledge 

 of none of these processes is complete, and 

 we know less about the actual working of 

 the bodily activities during thinking than 

 of many other functions. But fortunately 

 in this latter field we have direct aware- 

 ness, not of the physical processes of nerv- 

 ous conduction, etc., but of the experience 

 as such. There is mystery here but not 

 necessarily mysticism. Ignorance is not an 

 impassable barrier to scientific progress. 

 The thing to do is to widen our experience, 

 our factual knowledge, not to close the 

 door to such advance by magical formulae. 



When we think, there is protoplasmic 

 activity, chiefly In the brain, just as truly 

 as when we walk there Is protoplasmic 

 activity, In this case chiefly In the legs. 

 The internal activities and the organs em- 

 ployed are as different In the two cases as 

 are the functions themselves. 



Our awareness of what is going on (that 

 Is, of part of it) Is only one of the mani- 

 festations of a very complex process which 

 may include an external stimulus, various 

 Internal processes that can be demon-
