HO ELEMENTARY SCIENCE 



So it is equally clear that, as the world grows older, 

 the need of its young people for education becomes 

 greater. The education which was good enough for your 

 grandfather may not be good enough for you. Times 

 have changed. You must stay in school as long as you 

 can to make sure of earning a living. The modern 

 world into which you are going demands, above all 

 things, minds which are trained and well-informed. Mere 

 strength and smartness count for little in the world's 

 work of to-day, and they will count for less and less as 

 time goes on. 



The progress of man may be measured by the extent to 

 which he has put brains into his work. Indeed the prog- 

 ress of man may be defined as the process of putting 

 brains into work. It is the process of thinking in con- 

 nection with doing, the process of making behavior a ful- 

 filment of careful thought. This defines the progress of 

 the individual as well as of the race. It is a goal toward 

 which we all strive. 



Man's first use of labor-saving devices was probably 

 not reasoned out. It was more or less instinctive. He 

 felt his way, rather than thought his way to the doing of 

 certain things in certain ways. He learned by experience 

 rather than by reason. Thus the first primitive men who 

 pried up large stones with sticks, or threw small ones hi 

 slings, probably did these things without thinking much 

 about them. There is a scientific explanation as to why 

 it is easier to pry up a stone than to lift it, but a small 

 boy will do it without having any idea of the explanation. 

 Similarly such things were done in the childhood of the 

 race. The explanations came later. These explanations 

 were the beginnings of science.
