Man is made of opinions,—of truth and error; and his life is a warfare like all other lives before him.... Man goes on developing error upon error till he is buried in his own belief.... It is the office of wisdom to explain the phenomena in man called disease, to show how it is made, and how it can be unmade. This is as much a science as it is to know how to decompose a piece of metal.

Disease is the misery of our belief, happiness is the health of our wisdom, so that man's happiness or misery depends on himself. Now, as our misery comes from our belief, and not from the thing believed, it is necessary to be on the watch, so as not to be deceived by false guides. Sensation contains no intelligence or belief, but is a mere disturbance of the matter, called agitation, which produces mind, and is ready to receive the seed of error. Ever since man was created, there has been an element called error which has been busy inventing answers for every sensation.

Science is wisdom reduced to practice.

One thing is certain: the time will come when the opinions of priests and doctors must give way to the science of life; for their opinions lead to death and misery, and the science of life is health and happiness.

The silkworm spins out his life, and, wrapping himself in his labor, dies.

Now, I stand alone on this rock, fighting the errors of this world, and establish the science of life by my works. What is my mode of warfare? With the axe of truth I strike at the root of every tree of error and hew it down, so that there shall not be one error in man showing itself in the form of disease.
