Have patience with everything that remains unsolved in your heart. Try to love the questions themselves, like locked rooms and like books written in a foreign language. Do not now look for the answers. They cannot now be given to you because you could not live them. It is a question of experiencing everything. At present you need to live the question. Perhaps you will gradually, without even noticing it, find yourself experiencing the answer, some distant day.
The man who does not read has no advantage over the man who cannot read.
It has often and confidently been asserted, that man's origin can never be known: but ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.
—Charles Darwin in The Descent of Man
All you need is ignorance and confidence and the success is sure.
The most violent element in society is ignorance.
The greater the ignorance the greater the dogmatism.
The greatest of faults, I should say, is to be conscious of none.
The truest characters of ignorance are vanity and pride and arrogance.
