A Quote by Carl Sagan

Our perceptions are fallible. We sometimes see what isn't there. We are prey to optical illusions. Occasionally we hallucinate. We are error-prone.

It begins with skepticism. The history of human folly, and our own susceptibility to illusions and fallacies, tell us that men and women are fallible.

Steven Pinker

I was fascinated with optical illusions.

Temple Grandin

There are optical illusions in time as well as space.

Marcel Proust

To avoid the various foolish opinions to which mankind are prone, no superhuman genius is required. A few simple rules will keep you, not from all error, but from silly error.

Bertrand Russell

Of all the inanimate objects, of all men's creations, books are the nearest to us for they contain our very thoughts, our ambitions, our indignations, our illusions, our fidelity to the truth, and our persistent leanings to error. But most of all they resemble us in their precious hold on life.

Joseph Conrad

Human beings have illusions. The enlightened don't have illusions. They see things as they are, and in that seeing, they see ecstasy and joy. They see the play of life.

Frederick Lenz

Occasionally, something will happen that will change your opinion of someone irrevocably, that will shatter the ideal you've built up around a person and force you to see them for the fallible and human creature that they really are.

Marilyn Manson

We're left with so little to go on. Only the present is full enough to seem complete, and even that is an optical illusion. The moment is bleeding off the page. We live on the precipice of our perceptions. At the edge of every living instant, the world shears away like a cliff of ice into the sea of what is forgotten.

Ivan Vladislavic

Even better than good error messages is a careful design which prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action.

Jakob Nielsen

Remember that our reactions are a product of our perceptions, and our perceptions are a result of what is at the center of our life.

Stephen Covey

So be it. God created profoundly fallible creatures on this earth, and human history is mostly the story of error and accident.

Michael Ledeen

The only cure for loss of illusions is fresh illusions, more illusions, and always illusions.

William John Locke

We see the world, not as it is, but as we are -- or, as we are conditioned to see it. When we open our mouths to describe what we see, we in effect describe ourselves, our perceptions, our paradigms.

Stephen Covey

It is important for us to see that our mentors are human and therefore fallible; it makes our own shortcomings more tenable.

John Wooden

I assure you, Constable Morgan, I am quite sane, as I understand the word, perhaps the sanest person in this room, for I suffer from no illusions. I have freed myself, you see, from the pretense that burdens most men. Much like our prey, I do not impose order where there is none; I do not pretend there is any more than what there is, or that you and I are anything more than what we are. That is the essence of their beauty, Morgan, the aboriginal purity of their being, and why I admire them.

Rick Yancey

Error-prone or biased artificial-intelligence systems have the potential to taint our social ecosystem in ways that are initially hard to detect, harmful in the long term, and expensive - or even impossible - to reverse.
