It is not enough that you understand in what ignorance man and beast live; you must also have and acquire the will to ignorance. You need to grasp that without this kind of ignorance life itself would be impossible, that it is a condition under which alone the living thing can preserve itself and prosper: a great, firm dome of ignorance must encompass you.

For a man’s life would become intolerable, if he knew what was going to happen to him. He would be made aware of future evils, and would suffer their agonies in advance, while he would get no joy of present blessings since he would know how they would end. Ignorance is the necessary condition of human happiness, and it has to be admitted that on the whole mankind observes that condition well. We are almost entirely ignorant of ourselves; absolutely of others. In ignorance, we find our bliss; in illusions, our happiness.

Ignorance is the necessary condition, i do not say of happiness, but of life itself. If we knew everything, we could not endure existence a single hour. The sentiments that make it sweet to us, or at any rate tolerable, spring from a falsehood, and are fed on illusions.
If, like God, a man possessed the truth, the sole and perfect truth, and once let it escape out of his hands, the world would be annihilated there and then, and the universe melt away instantly like a shadow.

Unbelievers enjoy the security of their unbelief; there is great confidence in ignorance.

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

Yes, now you know. Now you know! That’s what it was to be alive. To move about in a cloud of ignorance; to go up and down trampling on the feelings of those . . . of those about you. To spend and waste time as though you had a million years. To be always at the mercy of one self-centered passion, or another. Now you know — that’s the happy existence you wanted to go back to. Ignorance and blindness.

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

If you want to be successful, it's just this simple. Know what you are doing. Love what you are doing. And believe in what you are doing.

To be truly ignorant, be content with your own knowledge.

«Ignorance more often begets confidence than knowledge.»

The person who knows only success can be more oblivious to all the pitfalls.

"the old maxim... "there are three things necessary to success in life — Impudence! Impudence! Impudence!

And in knowing that you know nothing makes you the smartest of all.

Our comforting conviction that the world makes sense rests on a secure foundation: our almost unlimited ability to ignore our ignorance.
