We don't know a millionth of one percent about anything.

[...} many things must remain uncertain, and many a question insoluble, because what we know of nature is by no means sufficient, in all cases, to explain what has to be explained.

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

"In its efforts to learn as much as possible about nature, modern physics has found that certain things can never be "known" with certainty. Much of our knowledge must always remain uncertain. The most we can know is in terms of probabilities."

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

Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are part of nature and therefore part of the mystery that we are trying to solve.

Let's say that you have an incredible one percent of all the knowledge in the universe. Would it be possible, in the ninety-nine percent of the knowledge that you haven't yet come across, that there might be ample evidence to prove the existence of God? If you are reasonable, you will be forced to admit that it is possible.

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.

If a fish in the ocean is what we do know, then the entire ocean is what we don’t. The universe is always going to remain the largest mystery.

Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve.

The existing scientific concepts cover always only a very limited part of reality, and the other part that has not yet been understood is infinite.

We understand many things about particles and their interactions, but this and other mysteries make it very clear that we are nowhere close to a full understanding.

How it is we have so much information, but know so little?

901. Halfe the world knowes not how the other halfe lies.
