Only a blind man can easily define what light is. When you do not know, you are bold. Ignorance is always bold; knowledge hesitates. And the more you know, the more you feel that the ground underneath is dissolving. The more you know, the more you feel how ignorant you are.

Ignorance lies not in the things you don't know, but in the things you know that ain't so.

...ignorance more frequently begets confidence than does knowledge...

Real knowledge is to know the extent of one’s ignorance. — Confucius The highest form of ignorance is when you reject something you don’t know anything about. — Wayne Dyer

«Ignorance more often begets confidence than knowledge.»

His Ignorance was as remarkable as his knowledge.

If there is something that opens horizons, it is precisely ignorance.

Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science.

The highest form of ignorance is when you reject something you don’t know anything about. — Wayne Dyer

Ignorance, to a scientist, is an itch that begs to be pleasurably scratched. Ignorance, if you are a theologian, is something to be washed away by shamelessly making something up.

Nothing in education is so astonishing as the amount of ignorance it accumulates in the form of inert facts.

The modern ignorance is in people's assumption that they can outsmart their own nature. It is in the arrogance that will believe nothing that cannot be proved, and respect nothing it cannot understand, and value nothing it cannot sell . . . The <i>next</i> hard time is just as real to him as the last, and so is the next blessing. The new ignorance is the same as the old, only less aware that ignorance is the same as the old, only less aware that ignorance is what it is. It is less humble, more foolish and frivolous, more dangerous. A man, Old Jack thinks, has no choice but to be ignorant, but he does not have to be a fool. He can know his place, and he can stay in it and be faithful.

Ignorance is bliss

Ignorance gives one a large range of probabilities.
