"If one man's thoughts so influence himself, family or friend, think of the influence of such thoughts on those who go to him for advice or treatment, those who deliberately place themselves under his inspection and allow themselves to be guided both directly and indirectly by his erroneous opinions. Think of the vast stream of such thoughts going out from all medical colleges, students and practitioners. No wonder diseases increase as physicians increase, as some of the best thinkers of the age declare. "Not that one class of people is more to be reflected upon than another, for some kind or degree of erroneous thought is held by all classes. Physicians talk sickness and death, ministers preach evil and punishment, the entire race believe in and suffer for sins. "It is centuries since it was first discovered that ideas were transmitted without the ordinarily accepted means of communication, but, to-day it is positively and repeatedly, yes, continually proven that thought transference is not only possible or probable, but an every-day occurrence. To realize that 'Thoughts are things. Endowed with being, breath and wings, And that we send them forth to fill The world with good results or ill,' is to be mightily responsible for what we think. To know that we are verily our brother's keeper, and that every thought makes misery or happiness for the whole world as well as for the individual, is something that should engage our deepest and most earnest consideration. "All thinking is for the weal or woe of the world that is yet in its infancy of knowledge. As consciousness of truth takes the place of consciousness of error, thoughts become light and beautiful and true with corresponding conditions. "Let us no longer slumber in the arms of indifference and ignorance, but awake to truth and righteousness. 'Better be unborn than untaught; for ignorance is the root of misfortune.'" CHAPTER XXIX. "Blessed influence of one true, loving soul on another. Not calculable by algebra, not deductible by logic, but mysterious, effectual, mighty as the hidden process by which the tiny seed is quickened, and bursts forth into tall stem and broad leaf, and glowing tasseled flower."--_George Eliot._ "Oh dear!" exclaimed Kate as she laid down the letter containing the lesson on Thought. "I didn't know we were so responsible for every little thing that comes into our mind." "Or goes out of it," said Grace, smiling, as she finished tinting a dainty plaque. "Now we can understand that 'where ignorance is bliss, 'tis folly to be wise,'" she added rather absent-mindedly. "Yes, but I think I prefer the wisdom to the bliss. Do you understand this lecture as well as the rest?" asked Kate, again glancing at the letter. "Why shouldn't we? It is plainly told, and is a natural sequence to the others. I should think it very helpful, and if there really is so much power in thought, it is time people knew it."
