“Knowledge will forever govern ignorance.”

“Knowledge will forever govern ignorance, and a people who mean to be their own governors, must arm themselves with the power knowledge gives. A popular government without popular information or the means of acquiring it, is but a prologue to a farce or a tragedy or perhaps both”

“I sold my soul for knowledge of the future, only to have that very pact render me forever ignorant (Gerald Tarrant).”

“Not ignorance, but ignorance of ignorance is the death of knowledge.”

“There is nothing so difficult as to persuade men that they are ignorant. Bertha, exaggerating the seriousness of the affair, thought it charlatanry to undertake a post without knowledge and without capacity. Fortunately that is not the opinion of the majority, or the government of this enlightened country could not proceed.”

“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”
