“Knowledge rests not upon truth alone, but upon error also.”

“The fundament upon which all our knowledge and learning rests is the inexplicable.”

“Certainly, it is heaven upon earth, to have a man's mind move in charity, rest in providence, and turn upon the poles of truth.”

“Although the pure truth has never been stated, nevertheless it has never been lost. Its existence does not depend upon human statement but upon human sensitivity. In this it is unlike all other knowledge.”

“Truth has to be repeated constantly, because Error also is being preached all the time, and not just by a few, but by the multitude. In the Press and Encyclopaedias, in Schools and Universities, everywhere Error holds sway, feeling happy and comfortable in the knowledge of having Majority on its side.”

“Of all the offspring of Time, Error is the most ancient, and is so old and familiar an acquaintance, that Truth, when discovered, comes upon most of us like an intruder, and meets the intruder's welcome.”
