88 DEATH AND RESURRECTION. 



nor feel, but which still exists. This 

 matter is then qualified by some other 

 form of energy by which it manifests 

 itself. Thus we comprehend ether as 

 light, heat and colors, all forces, as well 

 as gravity, electricity, etc. 



Already from these suggestions it is 

 evident that force is the only substan- 

 tial thing in the material world. With- 

 out force, matter is nothing that may 

 be comprehended either by the senses 

 or by the reason. What we call matter 

 is nothing but different kinds of en- 

 ergy.* We have space-occupying en- 

 ergy, chemical, electrical, mechanical 

 forms of energy, and so forth. 



How are these forms of energy re- 

 lated to each other? Between forms 

 so different as tones and light, colors 

 and mechanical work, there is at least 



*The latest researches in regard to the newly dis- 

 covered corpuscles show that these "bodies" have a 

 mass proportional to the square of their velocity, thus 

 forcing us to conclude that they at rest have no mass. 

 Perhaps, therefore, the ancient dualistic world of mat- 

 ter and force is merging into a larger unity where 

 life directs force to serve its specific purposes. — Trans-
