We keep, in science, getting a more and more sophisticated view of our essential ignorance.
Warren Weaver
A man may live long, and die at last in ignorance of many truths, which his mind was capable of knowing, and that with certainty.
John Locke
Ignorance seldom vaults into knowledge, but passes into it through an intermediate state of obscurity, even as night into day through twilight.
Samuel Taylor Coleridge
Ignorance is preferable to error, and he is less remote from the truth who believes nothing than he who believes what is wrong.
Thomas Jefferson
Ignorance is not so damnable as humbug, but when it prescribes pills it may happen to do more harm
George Eliot
Ignorance, when it is voluntary, is criminal; and he may be properly charged with evil who refused to learn how he might prevent it
Samuel Johnson
There is no means by which men so powerfully elude their ignorance, disguise it from themselves and from others as by words
Gamaliel Bradford
Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.
Charles Darwin
