Such thinking is likely to be productive in high degree if it be concrete, adapted to the actual state of the world, without too much theorizing, with a view to direct benefits. In Mr. Quimby's preliminary researches we find a capital instance. He began with a purely conventional point of view, defending in thought and attitude the prevailing mcdical practice of the day, and so he took the world as he found it. Moreover, he had a personal need. I undertake to say there is method of reasoning which, being understood, can seperate one from the other.
Men never diepute about a fact that can be demonstrated by scientific reasoning.
Controversies arise from some idea that has been turned into false direction, leading to a false position. Therefore, because person says a thing is no reason that what he says true. The greatest evil that follows taking an opinion for a truth is disease. Let medical and religious opinions, which produce so vast an amount of misery, be tested by the rule I have laid down, and it will be seen how much they are founded in truth. For twenty years I have been testing them, and I have failed to find one single principle of truth in either.
