"To be ignorant of one's ignorance is the malady of the ignorant"

Amos Bronson Alcott


"There are in fact four very significant stumblingblocks in the way of grasping the truth, which hinder every man however learned, and scarcely allow anyone to win a clear title to wisdom, namely, the example of weak and unworthy authority, longstanding custom, the feeling of the ignorant crowd, and the hiding of our own ignorance while making a display of our apparent knowledge."

Roger Bacon, (1220-1292) Source: Opus Majus, 1266-67


"The full area of ignorance is not mapped: we are at present only exploring its fringes."

J. D. Bernal, (1901-1971) Irish-born scientist

"The evil that is in the world always comes of ignorance, and good intentions may do as 
much harm as malevolence, if they lack understanding. On the whole, men are more good than
bad; that, however, isn't the real point. But they are more or less ignorant, and it is
that we call vice or virtue; the most incorrigible vice being that of an ignorance which
fancies it knows everything and therefore claims for itself the right to kill."

Albert Camus, The Plague, Modern Library Edition, p. 120

"Impartiality is a pompous name for indifference, which is an elegant name for ignorance."

G.K. Chesterton, The Speaker, 12/15/00


"Science is the topography of ignorance."

Oliver Wendell Holmes


"It is only when the people become ignorant and corrupt, when they degenerate into a populace, that they are incapable of exercising the sovereignty. Usurpation is then an easy attainment, and an usurper soon found. The people themselves become the willing instruments of their own debasement and ruin."

President James Monroe, First Inaugural Address, 1817


"No drug, not even alcohol, causes the fundamental ills of society. If we're looking for the sources of our troubles, we shouldn't test for drugs, we should test them for stupidity, ignorance, greed and love of power."

P.J. O'Rourke

"Reason and Ignorance, the opposites of each other, influence the great bulk of mankind. 
If either of these can be rendered sufficiently extensive in a country, the machinery of
Government goes easily on. Reason obeys itself; and Ignorance submits to whatever is
dictated to it."

Thomas Paine

"Our knowledge can only be finite, while our ignorance must necessarily be infinite."

Karl Popper


"We...are not really free if we can't control our own government and its policies. And we will never do that if we remain ignorant."

Charley Reese

"Every man is ignorant -- just on different subjects...."

Will Rogers
"An ignorant person is one who doesn't know what you have just found out."

Will Rogers

"Men are born ignorant, not stupid; they are made stupid by education."

Bertrand Russell


"Someone once said that the most important knowledge is knowledge of our own ignorance. 
Our schools are depriving millions of students of
that kind of knowledge by promoting
"self-esteem" and encouraging them
to have opinions on things of which they are grossly
ignorant, if not
misinformed."

Thomas Sowell


"He who is unaware of his ignorance will be only misled by his knowledge."

Richard Whately, (1787-1863)
