vni Introduction, 



the student is then working in harmony with 

 law. It is the violation of law that makes all 

 the trouble in the world whether physical, 

 moral, or social. When we speak of natural 

 law we do not confine ourselves to what is 

 commonly known as chemistry and physics, 

 and the laws that govern the material world, 

 but include as well the laws of our own being, 

 as intellectual and spiritual units. For all 

 law, physical, intellectual, and spiritual, is in 

 a sense natural. 



All departments of science are simply 

 branches of one great science, and all phases 

 of human activity are touched by it. The 

 preacher is a better preacher, the doctor a bet- 

 ter doctor, the lawyer a better lawyer, the edi- 

 tor a better editor, the business man a better 

 merchant, and the mechanic a better workman, 

 if they follow scientific methods. Indeed, any 

 man will be a better husband, father, and citi- 

 zen, if he has some trustworthy knowledge of 

 the laws under which this great universe, down 

 to his own little part of it, lives, moves, and 

 has its being.
