Part II: The Lessons
Lesson One: Introduction
In presenting these lessons in Mental Science to the public, it is my desire to make it possible for any one, who cares to take the time to study them, to demonstrate the truths that will be discussed. It is, perhaps, hard to set down in writing a complete teaching in Mental Science that will not appear difficult to understand; but this could be said as well of any science, and the Science of Mind is no exception to the general rule.
Science is knowledge of facts built around some proven principle. All that we know about any science is that certain things happen under certain conditions. Take electricity as an example; we know that there is such a thing as electricity; we have never seen it, but we know that it exists because we can use it; we know that it operates in a certain way and we have discovered the way it works. From this knowledge we go ahead and deduce certain facts about electricity; and, applying them to the general principle, we receive definite results. No one has ever seen the power or the energy that we call electricity; and the only proof we have that it really exists is that from it we receive light, heat and motive power.
No one has ever seen any of the great causes that lie back of the manifestations of life, and perhaps no one ever will; but we know that such principles exist because we can use them.
HOW LAWS ARE DISCOVERED
The discovery of a law is generally made more or less by accident, or by some one who, after careful thought and observation, has come to the conclusion that such a principle
