“Under the discipline of unity, knowledge and morality come together. No longer can we have that paltry 'objective' knowledge so prized by the academic specialists. To know anything at all becomes a moral predicament. Aware that there is no such thing as a specialized effect, one becomes responsible for judgments as well as facts. Aware that as an agricultural scientist he had 'one great subject,' Sir Albert Howard could no longer ask, What can I do with what I know? without at the same time asking, How can I be responsible for what I know?”

“We know too much, and what might have been excused in other times can no longer stand up to reason. ... with that understanding comes moral responsibility.”

“Iago’s treatment of Othello conforms to Bacon’s definition of scientific enquiry as putting Nature to the Question. If a member of the audience were to interrupt the play and ask him: "What are you doing? could not Iago answer with a boyish giggle, "Nothing. I’m only trying to find out what Othello is really like"? And we must admit that his experiment is highly successful. By the end of the play he does know the scientific truth about the object to which he has reduced Othello. That is what makes his parting shot, What you know, you know, so terrifying for, by then, Othello has become a thing, incapable of knowing anything.And why shouldn’t Iago do this? After all, he has certainly acquired knowledge. What makes it impossible for us to condemn him self-righteously is that, in our culture, we have all accepted the notion that the right to know is absolute and unlimited. […] We are quite prepared to admit that, while food and sex are good in themselves, an uncontrolled pursuit of either is not, but it is difficult for us to believe that intellectual curiosity is a desire like any other, and to realize that correct knowledge and truth are not identical. To apply a categorical imperative to knowing, so that, instead of asking, "What can I know?" we ask, "What, at this moment, am I meant to know?" – to entertain the possibility that the only knowledge which can be true for us is the knowledge we can live up to – that seems to all of us crazy and almost immoral. But, in that case, who are we to say to Iago – "No, you mustn’t.”

“I am just another blind man. I do not get the whole picture of what transpires in all places. I am blind and limited. I would be a fool to think myself wise. And so, not knowing what the universe means, I can only try to be responsible with the knowledge, the strength, and the time given to me.”

“I should have liked to be asked to say what I knew. They always tried to ask what I did not know. When I would have willingly displayed my knowledge, they sought to expose my ignorance. This sort of treatment had only one result: I did not do well in examinations”

“I am blind and limited. I would be a fool think myself wise. And so, not knowing what the universe means, I can only try to be responsible with the knowledge, the strength, and the time given to me. I must be true to my heart.”
