We know very little, and yet it is astonishing that we know so much, and still more astonishing that so little knowledge can give us so much power.

Science tells us what we can know, but what we can know is little, and if we forget how much we cannot know, we become insensitive to many things of great importance.

Very many maintain that all we know is still infinitely less than all that still remains unknown.

We live in an age in which there is too much information, less knowledge and even less wisdom. That ratio needs to be reversed. We definitely need less information, more knowledge, and much more wisdom.

Since we cannot know all that there is to be known about anything, we ought to know a little about everything.

We know so very little about this strange planet we live on, this haunted world where all answers lead only to more mystery.

And yet all I have said is but from common reading. And, let me ask, why, because we know but little, we are to be supposed to know nothing?

We live in a world saturated with information. We have virtually unlimited amounts of data at our fingertips at all times, and we’re well versed in the arguments about the dangers of not knowing enough and not doing our homework. But what I have sensed is an enormous frustration with the unexpected costs of knowing too much, of being inundated with information. We have come to confuse information with understanding.

The vast accumulations of knowledge — or at least of information — deposited by the nineteenth century have been responsible for an equally vast ignorance. When there is so much to be known, when there are so many fields of knowledge in which the same words are used with different meanings, when every one knows a little about a great many things, it becomes increasingly difficult for anyone to know whether he knows what he is talking about or not. And when we do not know, or when we do not know enough, we tend always to substitute emotions for thoughts.

We know hardly anything about anything.

Only a few know, how much one must know to know how little one knows.

The only reason people do not know much is because they do not care to know. They are incurious. Incuriousity is the oddest and most foolish failing there is.

It is a very sad thing that nowadays there is so little useless information.

I know too much and not enough
