Power rests on the kind of knowledge one holds. What is the sense of knowing things that are useless?

I can't believe that," said Seldon. "I should think that new copies would be made of any record in danger of withering. How could you let knowledge disappear?" "Undesired knowledge is useless knowledge," said Dors. "Can you imagine all the time, effort, and energy expended in a continual refurbishing of unused data? And that wastage would grow steadily more extreme with time.

It's where we're nearest to our humanness. Useless knowledge for its own sake. Useful knowledge is good, too, but it's for the faint-hearted, an elaboration of the real thing, which is only to shine some light, it doesn't matter where on what, it's the light itself, against the darkness, it's what's left of God's purpose when you take away God.

Knowledge is knowing that we cannot know.

In Greek fable, as in Christian, it is asserted that there is a forbidden knowledge which brings nothing into world but woe. Our generation has had ample demonstration of what that knowledge is. It is knowledge of the useful rather than the true and the good, of techniques rather than of ends.

You certainly are a repository of useless information. How do you know all that?' David asked, with more amusement than admiration.

'I have a mind like a magpie's, easily distracted by interesting odds and ends,' Ramses admitted.

As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power. You can think about only what you know, so you ought to learn something; on the other hand, you can know only what you have thought about.

To claim absolute knowledge is to become monstrous. Knowledge is an unending adventure at the edge of uncertainty.

The love of knowledge is a kind of madness.

Is it knowledge that is wanting? We Indians, born and bred in a country where Jnana has been stored and accumulated since the race began, bear about in us the inherited gains of many thousands of years.... But it is a dead knowledge, a burden under which we are bowed, a poison which is corroding us, rather than as it should be a staff to support our feet and a weapon in our hands; for this is the nature of all great things that when they are not used or are ill used, they turn upon the bearer and destroy him.

"Don't get me wrong, don Juan," I protested. "I want to have an ally, but I also want to know everything I can. You yourself have said that knowledge is power."
"No!" he said emphatically. "Power rests on the kind of knowledge one holds. What is the sense of knowing things that are useless?"

Knowledge, a rude unprofitable mass, The mere materials with which wisdom builds, Till smoothed and squared and fitted to its place, Does but encumber whom it seems to enrich. Knowledge is proud that he has learned so much; Wisdom is humble that he knows no more. Books are not seldom talismans and spells.

When you are young you are curious to know all about everything, why the sun shines, what the stars are, all about the moon and the world around us; but as we grow older, knowledge becomes a mere collection of information without any feeling.
