“Good thoughts and actions can never produce bad results; bad thoughtsand actions can never produce good results … We understand this law inthe natural world, and work with it; but few understand it in the mentaland moral world—although its operation there is just as simple and undeviating—and they, therefore, do not cooperate with it.”

“But goodness alone is never enough. A hard, cold wisdom is required for goodness to accomplish good. Goodness without wisdom always accomplishes evil.”

“. . .It is the Law that while Evil, unopposed, may accomplish terrible deeds, the power of Good can never be overthrown when opposed to Evil. . .”

“A "simple aspect of science" may be defined as one which, through good fortune, I happen to understand.”

“I still do not understand why some people think they mean nothing to anyone; while their simple smile gives unlimited reasons for others to live.”
