“... informed ignorance provides the natural state of mind for research scientists at the ever-shifting frontiers of knowledge. People who believe themselves ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is known and unknown in the cosmos.”

“But you can’t be a scientist if you’re uncomfortable with ignorance, because scientists live at the boundary between what is known and unknown in the cosmos. This is very different from the way journalists portray us. So many articles begin, “Scientists now have to go back to the drawing board.” It’s as though we’re sitting in our offices, feet up on our desks—masters of the universe—and suddenly say, “Oops, somebody discovered something!” No. We’re always at the drawing board. If you’re not at the drawing board, you’re not making discoveries. You’re not a scientist; you’re something else. The public, on the other hand, seems to demand conclusive explanations as they leap without hesitation from statements of abject ignorance to statements of absolute certainty.”

“The world is a good judge of things, for it is in natural ignorance, which is man's true state. The sciences have two extremes which meet. The first is the pure natural ignorance in which all men find themselves at birth. The other extreme is that reached by great intellects, who, having run through all that men can know, find they know nothing, and come back again to that same ignorance from which they set out; but this is a learned ignorance which is conscious of itself. Those between the two, who have departed from natural ignorance and not been able to reach the other, have some smattering of this vain knowledge and pretend to be wise. These trouble the world and are bad judges of everything. The people and the wise constitute the world; these despise it, and are despised. They judge badly of everything, and the world judges rightly of them.”

“I examined the poets, and I look on them as people whose talent overawes both themselves and others, people who present themselves as wise men and are taken as such, when they are nothing of the sort.From poets, I moved to artists. No one was more ignorant about the arts than I; no one was more convinced that artists possessed really beautiful secrets. However, I noticed that their condition was no better than that of the poets and that both of them have the same misconceptions. Because the most skillful among them excel in their specialty, they look upon themselves as the wisest of men. In my eyes, this presumption completely tarnished their knowledge. As a result, putting myself in the place of the oracle and asking myself what I would prefer to be — what I was or what they were, to know what they have learned or to know that I know nothing — I replied to myself and to the god: I wish to remain who I am.We do not know — neither the sophists, nor the orators, nor the artists, nor I— what the True, the Good, and the Beautiful are. But there is this difference between us: although these people know nothing, they all believe they know something; whereas, I, if I know nothing, at least have no doubts about it. As a result, all this superiority in wisdom which the oracle has attributed to me reduces itself to the single point that I am strongly convinced that I am ignorant of what I do not know.”

“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 dream of a true husband—a good man, not a brute, nor a champion of men on the battlefield; I dream but of a gentle man, one who neither speaks too loud nor ignores evil. I pray for such a like-minded mate, who will be ever for me like harmony to music, virtue to the soul, prosperity to the state, and forethought to the universe.”
