BIOLOGY AND PROGRESS 221 



mental characteristics of life dominate over all 

 others instead of being co-equal. Until the 

 significance of the food-getting reflexes and the 

 self-protective reflexes are as critically analyzed 

 as that of the reproductive reflexes and the whole 

 united into one general process, after we come to 

 understand the appropriate stimuli for these proc- 

 esses, we shall not have made an adequate study 

 of the origin of the mind of man. 



There is great promise of progress in this field 

 in the coming years. Already we have discovered 

 much that is similar in the way that man and 

 animals learn with animals quickly reaching their 

 limit but with man ever extending his limits. 



In this brief sketching of some of the more 

 probable fields of progress which will give a bet- 

 ter understanding of man, no revolutionary 

 changes are anticipated nor is it suggested that 

 fundamental laws will be altered. Progress must 

 rather be in conformity with those principles 

 which clearly indicate that we must recognize the 

 ineradicable influence of heredity and that the 

 right to be well-born has a scientific foundation; 

 that good food and a wholesome environment 

 play an important part in well being; that the 

 period of natural growth cannot be shortened nor 

 the days of mankind lengthened; and that man- 

 kind cannot ignore nor set aside these basal rela- 

 tions.
