Knowledge Limitations Quotes

When a scientist doesn't know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty darn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty - some most unsure, some nearly sure, but none absolutely certain.

There is nothing so stupid as the educated man if you get him off the thing he was educated in.

Many women try to advance in their careers by having all the answers; by being the go-to person for information and advice; or by building expertise in a particular field.

He who knows best knows how little he knows.

Science is not the affirmation of a set of beliefs but a process of inquiry aimed at building a testable body of knowledge constantly open to rejection or confirmation. In science, knowledge is fluid and certainty fleeting. That is at the heart of its limitations. It is also its greatest strength.

Good policy analysis recognizes that physical truth may be poorly or incompletely known. Its objective is to evaluate, order, and structure incomplete knowledge so as to allow decisions to be made with as complete an understanding as possible of the current state of knowledge, its limitations, and its implications.

The clever men at Oxford, know all that there is to be knowed. But they none of them know one half as much, as intelligent Mr. Toad.

That knowledge which stops at what it does not know, is the highest knowledge.

It is paradoxical, yet true, to say, that the more we know, the more ignorant we become in the absolute sense, for it is only through enlightenment that we become conscious of our limitations. Precisely one of the most gratifying results of intellectual evolution is the continuous opening up of new and greater prospects.

I would suggest that today, we know about as much concerning the human mind as we knew about the galaxy in 1300.

I prefer true but imperfect knowledge, even if it leaves much undetermined and unpredictable, to a pretense of exact knowledge that is likely to be false.

We know a great deal, but our ignorance is sobering and boundless. With each step forward, with each problem which we solve, we not only discover new and unsolved problems, but we also discover that where we believed that we were standing on firm and safe ground, all things are, in truth, insecure and in a state of flux.

Without willing it, I had gone from being ignorant of being ignorant to being aware of being aware. And the worst part of my awareness was that I didn't know what I was aware of.

And what avails it that science has come to treat space and time as simply forms of thought, and the material world as hypothetical, and withal our pretension of property and even of self-hood are fading with the rest, if, at last, even our thoughts are not finalities, but the incessant flowing and ascension reach these also, and each thought which yesterday was a finality, to-day is yielding to a larger generalization?

It is strange that we know so little about the properties of numbers. They are our handiwork, yet they baffle us; we can fathom only a few of their intricacies. Having defined their attributes and prescribed their behavior, we are hard pressed to perceive the implications of our formulas.

Have you come over time to think that you know more now than you did when you were young, know less now than when young, know now there is so much more to know than you knew there was to know when young that it is moot whether you think you knew more then than now or less, or do you now know that you never knew anything at all and never will and only the bluster of youth persuaded you that you did or would?

Now that physics is proving the intelligence of the universe what are we to do about the stupidity of mankind? I include myself. I know that the earth is not flat but my feet are. I know that space is curved but my brain has been condoned by habit to grow in a straight line. What I call light is my own blend of darkness. What I call a view is my hand-painted trompe-l'oeil. I run after knowledge like a ferret down a ferret hole. My limitations, I call the boundaries of what can be known. I interpret the world by confusing other people's psychology with my own.
