the state of alternation between hope and fear — interrupted stimula- 

 tion, suffers so many bodily impairments and even diseases. It ex- 

 plains the slow dying away of animals in captivity. It explains the 

 grave digestive and metabolic disturbance under any nerve strain — 

 especially under the strain of fear, and the great benefits of con- 

 fidence and hope ; it explains the nervousness, loss of weight, indi- 

 gestion — in short the comprehensive physical changes that are

wrought by fear and sexual love and hate, On this hypothesis 

 we can understand the physical influence of one individual over 

 the body and personality of another; and of the infinite factors in 

 environment that play a role in the functions of many of our organs 

 all through phylogeny and association. It is because we were 

 evolved as motor beings on the uncompromising law of survival of 

 the fittest, hence it is that we are not in possession of any organs or 

 faculties which have not served our progenitors in their survival in 

 the relentless struggle of organic forms with each other. We are 

 now as we were then essentially motor beings and our only way of 

 responding to the dangers in our environment is by a motor re- 

 sponse. Such a motor response implies the integration of our 

 entire being for action and the activity of certain glands such as the 

 adrenals, the thyroid, the liver, etc., resulting in the throwing into 

 the blood stream substances which help to form energy, but which 

 if no muscular action ensues are harmful elements in the blood.
