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.

We don't know much about our current selves, do we?

And what is the use of knowing many things if, when you have learned the dimensions of heaven and earth, the measure of the seas, the courses of stars, the virtues of plants and stones, the secrets of nature, you still don’t know yourself?

It is more important to know that you don't know, than to know what you know.

Life is not about what you know. It’s about what you don’t know. And we never know enough. That’s good news for the both of us. It means that until the day we die, we can keep learning.

We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified — how can you live and not know? It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don't know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.

You see, one thing is, I can live with doubt and uncertainty and not knowing. I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of certainty about different things, but I'm not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here, and what the question might mean. I might think about it a little bit and if I can't figure it out, then I go on to something else, but I don't have to know an answer, I don't feel frightened by not knowing things, by being lost in a mysterious universe without having any purpose, which is the way it really is so far as I can tell. It doesn't frighten me.

The more you know, the more you know you don't know.

We need to accept our ignorance and say ‘I don’t know’ more often.

For it is really better for us not to know a thing, because [God] has not revealed it to us, than to know it according to man’s wisdom, because he has been bold enough to assume it.

you know far less about yourself than you feel you do.

You already know what you know, after all — and, unless your life is perfect, what you know is not enough. You remain threatened by disease, and self-deception, and unhappiness, and malevolence, and betrayal, and corruption, and pain, and limitation. You are subject to all these things, in the final analysis, because you are just too ignorant to protect yourself. If you just knew enough, you could be healthier and more honest. You would suffer less. You could recognize, resist and even triumph over malevolence and evil. You would neither betray a friend, nor deal falsely and deceitfully in business, politics or love. However, your current knowledge has neither made you perfect nor kept you safe. So, it is insufficient, by definition — radically, fatally insufficient.

In the world everyone knows enough to pursue what he does not know, but no one knows enough to pursue what he already knows. Everyone knows enough to condemn what he takes to be no good, but no one knows enough to condemn what he has already taken to be good.
