GENERAL PRINCIPLES II 



will be more men employed in dairying, and that industry will 

 then grow in magnitude and importance, even though no more 

 milk is produced per capita than now. Thus the gain resulting 

 from a higher civilization and a higher standard of living is not 

 exclusively, though it is mainly, on the side of the secondary indus- 

 tr es. There are other causes, however, which tend to stimulate 

 the growth of the secondary industries at the expense of the 

 primary. Among these may be mentioned the invention of farm 

 machinery, which is manufactured in the cities, and by means 

 of which labor is saved on the farms, thus tending to reduce, 

 relatively to the city population at least, the number of people 

 living on the farms. But whatever may happen in the very 

 distant future, it still remains true, taking the world over, that 

 agriculture is the greatest industry. 



Extracting a living from other men. It was remarked at the 

 beginning of this chapter that when we consider man as a race 

 we find that he must get his living out of the material world. 

 As an individual, however, we shall find that, even when he 

 is following an economic method of getting a living, he does 

 not always get it out of the material world, and that his indi- 

 vidual success does not always depend upon his ability to con- 

 trol or direct the forces of physical nature. It sometimes 

 depends upon his power to direct and control other men, and 

 sometimes upon his ability to please them. Controlling other 

 men in the sense of governing them, persuading them, leading 

 them in the right direction, and stimulating them to higher 

 endeavor, is of the greatest possible assistance in the task of 

 subjugating nature and remaking the earth, and they who are 

 able to do this are among the greatest of men. Even though 

 such men frequently have little knowledge of the natural world 

 and little aptitude for the actual work of controlling and directing 

 physical forces, nevertheless they know men, they understand 

 the human heart, and they are experts in directing the forces
